WCF SECTION SPECIAL BULLETIN #22-16 – 2100 EDT – 9/29/22

HURRICANE IAN – 2100 EDT – 9/29/22

Hurricane Ian, which was a Category 4 at landfall yesterday, crossed the State of Florida and exited the Florida east coast earlier this afternoon as a Tropical Storm.  Ian is now off of the Florida east coast, east of St. Augustine, and has re-intensified to a Category 1 hurricane.  Ian is headed for a second landfall in the United States just north of Charleston, South Carolina, and move inland and travel just east of Rock Hill, SC and Charlotte, NC as a Tropical Storm.

Conditions over the ARRL West Central Florida Section will continue to improve tonight and tomorrow.  Now over two million people in the State of Florida are without electrical power and many have damage to their homes.  So if you are in the dark tonight and or have damage to your home, you are not alone.  Help your friends and neighbors if you are able to do so.

FORECAST DISCUSSION:

The following excerpt is from the Forecast Discussion issued at 1700 EDT today:

“Ian remains a hybrid tropical cyclone with characteristics of an extratropical low, including a comma-pattern on satellite images and some frontal features in the outer circulation. The cyclone continues to have a warm core, however, and all indications are that it will re-develop strong convection over the center overnight.  Based on Melbourne Doppler radar velocity data of persistent 70-80-kt winds from 5-10 thousand feet, and earlier sustained winds of about 60 kt near that band from an observation in New Smyrna Beach, the initial wind speed is raised to 65 kt. This makes Ian a hurricane again. An Air Force Reserve Hurricane Hunter aircraft is scheduled to fly through Ian this evening and will provide a
better intensity estimate.

Ian finally appears to be making more of a turn to the north-northeast this afternoon. The hurricane should turn to the north overnight due to the incoming trough diving southward over the southern United States and then north-northwestward on Saturday with an increase in forward speed. While the overall synoptic pattern is similar in all of the models, Ian has been uncooperative and remains right of the previous track. Thus, the new forecast is adjusted to the east, and lies east of the model consensus.  Assuming Ian re-develops thunderstorms near the core overnight, it should take the expected north-northwest turn, but this shouldn’t be considered a confident forecast yet. Because of the
uncertainty, the Hurricane Warning has been extended eastward into North Carolina to Cape Fear.

The hurricane is moving over the Gulf Stream for the next day or so, where it has some time for further re-intensification.  Additionally, the trough interaction should provide a baroclinic energy kick. These factors point to some strengthening before landfall tomorrow. The new forecast is close to the GFS and regional hurricane models and is a bit stronger than before. It should be emphasized that while we don’t expect Ian to be a classic
hurricane at landfall, this does not diminish the danger it poses.  Strong winds and storm surge will also extend far from the center and will begin well before the center arrives.”

SITUATION AND ACTIONS:

As of 1700 EDT today, all of the Tropical Storm and Hurricane Watches and Warnings were discontinued earlier today.  The only watches or warnings still in effect are:

  • Rip Current Statement:  Coastal Pasco, Pinellas, Hillsborough, Manatee, Sarasota, and Charlotte Counties
  • Flood Warnings:  Peace River in Polk, Hardee, Desota, and Charlotte Counties.

The ARRL West Central Florida Section ARES remains at a Level 1 alert until more ARES groups.  Pasco County ARES and Manatee County ARES demobilized earlier today.  As far as we know, all other ARES groups are still partially or fully mobilized.

Note:  The Section ARES Alert Level simply reflects the activation status of local ARES groups in the ARRL West Central Florida Section.  Each ARES groups activates at the request of their served agencies and or in accordance with their local ARES plan.

Section ARES Alert Levels:
Level 3:   One or more ARES groups on Standby for possible activation in one or more WCF Counties.
Level 2:  One or more WCF Section ARES Groups are activated.
Level 1:  All WCF Section ARES Groups are activated.

All ARES, ACS, and CERT personnel are encouraged to continue to check each advisory issued by the National Hurricane Center in Miami and the Tropical Weather Outlook issued four times daily by the National Hurricane Center.

CONCLUSION

This will be the last special bulletin for Hurricane Ian, unless it somehow threatens the ARRL West Central Florida Section, which is very unlikely.

WCF SECTION SPECIAL BULLETIN #22-15 – 1900 EDT – 9/29/22

SECTION NET CANCELLATIONS FOR 9/29/22

Due to the impact of Hurricane Ian in the ARRL West Central Florida Section and ongoing priority to emergency communications the Eagle Net scheduled for this evening at 2030 hours and the West Central Florida Section Technical Net scheduled for this evening at 2100 or immediately following the Eagle Net have both been cancelled.

The Eagle Net will resume normal operation on Friday September 30, 2022 at 2030 EDT and the West Central Florida Section Technical Net will resume normal operation next Thursday October 6, 2022 at 2100 EDT.

Everyone be safe and just remember, if you are without power you are not alone.  Nearly two million people in Florida are in the same position as yourself.  Take care of one another.

FORECAST DISCUSSION:

The following excerpt is from the Forecast Discussion issued at 1700 EDT today:

“An Air Force Reserve Hurricane Hunter aircraft provided the last fix on Ian just before the hurricane made landfall at Cayo Costa, Florida, with the landfall time near at 305 pm EDT. The minimum pressure had risen to about 940 mb at landfall, suggesting that the winds had come down slightly, and the landfall intensity was estimated near 130 kt. While there hasn’t been much in situ data recently, satellite images show that the eye has become more cloud filled, and Tampa Doppler radar data is indicating a gradual reduction in winds. The initial intensity is set to 120 kt on this advisory.

Further weakening is forecast while Ian moves over central Florida during the next day and emerges into the western Atlantic later on Thursday. While there is a lot of vertical wind shear in the environment there, a favorable trough interaction from a trough in the southern United States is expected to counteract the shear, resulting in Ian staying a strong tropical storm through landfall on the southeast U.S. coast. Little change was made to the intensity forecast, which is near or somewhat above the consensus guidance.

The hurricane is moving to the north-northeast at about 8 kt. The aforementioned trough is likely to cause Ian to turn northward over the western Atlantic and to the north-northwest by the weekend. Model guidance is just a bit faster to the north-northeast than the last cycle, and the new forecast is nudged in that direction. The trough will probably cause Ian to transition to an extratropical cyclone in a few days over the southeastern United States, and this new forecast reflects this likelihood.”

SITUATION AND ACTIONS:

As of 1700 EDT today, all of the ARRL West Central Florida Section is still under a Hurricane Warning, with the exception of Pasco County, which is under a Tropical Storm Warning.  The following tropical watches and warnings weaare in effect for the ARRL West Central Florida Section:

  • Tropical Storm Warning:  Pasco County.
  • Hurricane Warning:  Pinellas, Hillsborough, Manatee, Sarasota, Charlotte Counties on the coast and Polk, Hardee, Highlands, and Desoto Counties in the interior. Counties.
  • Storm Surge Warning:  Pasco, Pinellas, Hillsborough, Manatee, Sarasota, and Charlotte Counties.

The ARRL West Central Florida Section ARES remains at a Level 1 alert, as all ARES groups in the Section have been activated as of 1100 EDT.  This is the first time that a Section ARES Level 1 alert has been issued since Hurricane Irma in 2017.

Note:  The Section ARES Alert Level simply reflects the activation status of local ARES groups in the ARRL West Central Florida Section.  Each ARES groups activates at the request of their served agencies and or in accordance with their local ARES plan.

HURRICANE IAN – 1900 EDT – 9/27/22

Hurricane Ian is now Category 3, which makes it a major hurricane, on Tuesday morning.  Ian is now in the southeastern Gulf of Mexico, moving north-northeast towards the Florida west coast and is predicted, as of 1700 today, to make landfall around 1600 to 1800 EDT tomorrow afternoon somewhere near the Charlotte and Sarasota county line, then weaken rapidly once moving inland toward the west side of Polk County.  As we have said before, we will dealing with Ian for most of this week, so this will not be a quick “ride” to say the least.

FORECAST DISCUSSION:

The following excerpt is from the Forecast Discussion issued at 1700 EDT today:

“The pressure on the last Air Force Hurricane Hunter aircraft fix fell to about 952 mb, indicating that Ian is restrengthening over the southeastern Gulf of Mexico. The eye of Ian remains well-defined on visible imagery, although radar data from Key West
suggest that an eyewall replacement could be in the initial stages. The initial wind speed is set to 105 kt, matching a blend of earlier SFMR and flight-level wind data. The plane data also showed that the area of hurricane-force winds is growing on the east side of the cyclone.

Ian is moving east-of-due-north, or 010/9-kt, with occasional wobbles to the north-northeast. A track toward the north-northeast is expected for the next couple of days while it moves between a ridge over the Bahamas and a trough over the western Gulf of Mexico.
There has been some model convergence this afternoon showing Ian remaining stronger and vertically deeper through landfall. This solution results in a faster track, again adjusted to the southeast, and the new forecast is moved in that direction. This new NHC track is close to the corrected model consensus and between the quicker ECMWF and slower GFS models. It should be emphasized that this track remains uncertain, with a typical spread in the steering features leading to big speed and track differences down the line, not to mention the oblique angle of approach to Florida. In a few days, more of the guidance is showing Ian interacting with a shortwave trough over the southeastern United States, causing the system to move back over the northwestern Atlantic in the longer
range, before turning northwestward back over land. The day 3-5 track forecast is also shifted eastward, although significant re-strengthening is not expected at long range.

The outflow pattern of the hurricane is beginning to be impinged upon in the southwestern quadrant, a sign that upper-level southwesterly flow is starting to affect the outer circulation. While the shear should increase up through landfall, it is just too close-to-call whether it starts to weaken Ian or not, or whether the larger system is able to resist the shear. Additionally, an eyewall replacement cycle could be in its initial phases, although predicting these structural changes is extremely difficult. The new forecast is near the last one, a little higher than the consensus. I should note that whether Ian comes ashore as category 4 hurricane or a large category 3 after an eyewall cycle, avoiding a large and destructive hurricane for Florida seems very unlikely, and residents should heed the advice of local emergency management officials.

The new forecast necessitates a Hurricane Warning for portions of extreme southwestern Florida, and a Tropical Storm Warning for the rest of southeastern Florida that wasn’t previously under a warning. Users are reminded to not focus on the exact track as some
additional adjustments to the track are possible. Significant wind, storm surge, and rainfall hazards will extend far from the center.”

SITUATION AND ACTIONS:

As of 1700 EDT today, all of the ARRL West Central Florida Section is under a Hurricane Warning, with the exception of Pasco County, which is under a Tropical Storm Warning.  The following tropical watches and warnings are in effect for the ARRL West Central Florida Section:

  • Tropical Storm Warning:  Pasco County.
  • Hurricane Warning:  Pinellas, Hillsborough, Manatee, Sarasota, Charlotte Counties on the coast and Polk, Hardee, Highlands, and Desoto Counties in the interior. Counties.
  • Storm Surge Warning:  Pasco, Pinellas, Hillsborough, Manatee, Sarasota, and Charlotte Counties.

As of 1500 EDT today, ARRL West Central Florida Section ARES went to a Level 1 alert, as all ARES groups in the Section have been activated with the exception of Hardee County.  This is the first time that a Section ARES Level 1 alert has been issued since Hurricane Irma in 2017.

Note:  The Section ARES Alert Level simply reflects the activation status of local ARES groups in the ARRL West Central Florida Section.  Each ARES groups activates at the request of their served agencies and or in accordance with their local ARES plan.

HURRICANE IAN – 2100 EDT – 9/26/22

Hurricane Ian is forecast to continue strengthening into a Category 3, which makes it a major hurricane, on Tuesday morning.  Ian is now moving northwest and will make landfall on the west side of Cuba early tomorrow morning and emerge into the Gulf of Mexico tomorrow afternoon.  Then, Ian will begin its journey towards the Florida west coast where it will eventually will run somewhat parallel with the Florida west coast and make landfall in the proximity of Hernando and Citrus County late on Thursday or early on Friday.

Also the National Hurricane Center has upgraded the Hurricane Watch and Tropical Storm Watch, to a Hurricane Warning and Tropical Storm Warning.  Ian is expected to move much more slowly north just off of coast, than was expected yesterday and earlier today.  We will dealing with Ian for most of this week, so this will not be a quick “ride” to say the least.

FORECAST DISCUSSION:

The following excerpt is from the Forecast Discussion issued at 1700 EDT today:

“Ian continues to strengthen over the northwestern Caribbean Sea. The last report from the Air Force Hurricane Hunters around 1630 UTC found 700-mb flight-level winds of 79 kt. The inner core appears better organized, and the eyewall structure has greatly improved in radar imagery from the Cayman Islands. The 18 UTC satellite classifications from SAB and TAFB were a consensus T4.5/77 kt, but the continued improvement in satellite structure warrants raising the initial intensity to 85 kt for this advisory.

Atmospheric and oceanic conditions remain very favorable for additional intensification during the next 24 h or so, as Ian moves over the very warm waters of the northwestern Caribbean Sea and the southeastern Gulf of Mexico while the shear remains quite low. The
NHC intensity forecast calls for Ian to become a major hurricane before it reaches western Cuba early Tuesday. It is then forecast to reach its peak intensity over the southeastern Gulf of Mexico in 36 h. After that, southwesterly shear in association with a deep-layer
trough over the eastern U.S. is forecast to significantly increase over the hurricane on Wednesday and Thursday, which will likely disrupt the vertical structure and import drier air into its circulation. Despite these less favorable conditions, Ian is still forecast to remain at or near major hurricane strength as it passes near the west-central coast of Florida on Wednesday and Thursday.  The NHC intensity forecast agrees well with the latest IVCN and HCCA aids.

Ian has made an expected turn toward the north-northwest, and its initial motion is 330/11 kt. The hurricane will move north-northwestward to northward over the next day or so as it is steered by a mid-level ridge to the east. A turn to the north-northeast with a decrease in forward speed is forecast on Wednesday and Thursday as the center of Ian moves near the west coast of Florida. The slower forward motion is likely to prolong the
storm surge, wind, and rainfall impacts, especially along the west coast of Florida. The latest track guidance has come into better agreement on this scenario, although it is noted that small deviations to the shore-parallel track could have large implications on the impacts at particular locations along the west coast of Florida. The NHC track forecast has again been adjusted slightly eastward at 48-72 h, which follows the latest trends in the global model guidance and lies near but just west of the multi-model consensus aids.

Based on the latest forecast and timing of expected impacts, Hurricane and Storm Surge Warnings have been issued along the west coast of Florida.”

FORECAST DISCUSSION:

The following excerpt is from the Forecast Discussion issued at 1700 EDT today:

“The satellite presentation of Ian has improved this morning. Deep convection has increased within the inner core during the pastseveral hours, with an expanding central dense overcast noted in recent satellite imagery. The inner core structure continues to take shape in radar data, although the eyewall still has a banded appearance and remains open on the west side. Dropsonde data from the NOAA and Air Force Hurricane Hunter aircraft indicate that the minimum pressure has gradually fallen to about 980 mb, and the
initial intensity is raised slightly to 70 kt for this advisory.

The intensity of Ian has increased by 30 kt during the past 18 h.  Further rapid intensification (RI) is expected during the next 24-36 h as Ian crosses the high oceanic heat content of the northwestern Caribbean Sea within a very low vertical wind shear (VWS) environment. The latest SHIPS-RI probabilities continue to highlight the high likelihood of this scenario, with a 73 percent chance of a 35-kt wind speed increase in 24 h and a 79 percent chance of a 45-kt increase in 36 h. The NHC intensity forecast is similar to the previous one, and it shows Ian becoming a major hurricane by the time it reaches western Cuba. Ian is forecast to reach its peak intensity in 36 h over the southeastern Gulf of Mexico. Then, increasing southwesterly shear by 36-48 h is expected to bring an end to the intensification phase. The combination of strong VWS and drier mid-level air will induce weakening thereafter, but Ian is expected to remain at or near major hurricane strength as it passes near the west-central coast of Florida on Wednesday and Thursday.

Ian continues to move northwestward at 325/11 kt. A turn toward the north-northwest and north is expected during the next day or so as the hurricane moves around the western extent of a mid-level ridge. Then, an upper-level trough over the eastern U.S. should cause Ian to turn more north-northeastward through Thursday. This track brings
the center of Ian close to the west-central coast of Florida during the middle of the week. An even greater concern is the slower forward motion that is forecast during this period, as the upper trough passes north and east of Ian and the steering currents weaken. This would likely prolong the storm surge, wind, and rainfall impacts along the affected portions of the west coast of Florida, although the roughly shore-parallel track still makes it
difficult to pinpoint exactly what locations will experience the most severe impacts. The track guidance has come into better agreement during the first 72 h of the forecast period, and only a minor eastward adjustment was made to the NHC track forecast in line
with the multi-model consensus aids.

The aircraft data indicate that the 34-kt wind radii in the northeastern quadrant were 20-30 n mi larger than previously estimated, and this has been reflected in the latest forecast.  Based on these changes, Tropical Storm Watches have been issued for
the middle Florida Keys and extended southward along the southwestern coast of Florida.”

SITUATION AND ACTIONS:

All of the ARRL West Central Florida Section is either under a Tropical Storm Watch or a Hurricane Watch.  The following tropical watches and warnings are in effect for the ARRL West Central Florida Section:

FORECAST DISCUSSION:

The following excerpt is from the Forecast Discussion issued at 1700 EDT today:

“The organization of Ian has not changed much since this morning. There have been some small bursts of convection closer to the center of the storm this afternoon, but the activity has not yet led to any notable changes in its structure. In fact, the most persistent convection has been in outer rain bands well to the northeast of the circulation near Jamaica. The SFMR wind data and adjusted flight-level winds from the earlier reconnaissance flights supported surface winds of 35-40 kt, and the initial intensity is set at 40 kt for this advisory. A NOAA Hurricane Hunter aircraft is scheduled to investigate Ian later tonight.

The center of Ian has jogged a bit northward this afternoon, but its longer-term motion is west-northwestward at 300/10 kt. A generally northwestward motion is expected tonight, followed by a north-northwestward motion on Monday and early Tuesday as it moves across the northwestern Caribbean Sea and near or over western Cuba. From there, the track guidance still diverges at days 3-5 as Ian is forecast to move northward across the eastern Gulf of Mexico. The ECMWF and UKMET models still lie on the eastern edge of the guidance and bring the center of Ian over the coast of west-central Florida, while the HWRF and HMON models are on the western side of the envelope and show Ian approaching the central Florida panhandle. Notably, the GFS has trended slightly eastward for the past few cycles, which has brought the multi-model consensus aids a bit eastward as well. The latest NHC track forecast has been adjusted in this direction, but only on the order of 15-20 n mi in the extended range. Users are reminded not to focus on the details of the track forecast at longer time ranges, since uncertainty is still high and future adjustments may be required.

Although the storm has yet to develop an inner core, the conditions over the northwestern Caribbean Sea appear very likely to support strengthening once it becomes better organized. Some dry environmental air may have limited convection today, but the GFS- and ECMWF- simulated satellite imagery indicate that deep convection will increase during the diurnal maximum period overnight. Then, significant strengthening is expected with low deep-layer shear and high oceanic heat content along the forecast track. There is still strong support for rapid intensification in the latest intensity guidance, and the NHC intensity forecast shows Ian becoming a hurricane on Monday and a major hurricane on Tuesday. This forecast remains close to the IVCN multi-model consensus, with some model aids including HCCA showing even higher peak intensities. Strong southwesterly shear develops over Ian by 72 h related to interaction with an upper-level trough, and the structure of the cyclone could significantly degrade before landfall given these hostile conditions. However, Ian is likely to have an expanding wind field and will be slowing down by that time, which will have the potential to produce significant wind and storm surge impacts across portions of the Florida west coast and the Florida panhandle.”

SITUATION AND ACTIONS:

ARRL West Central Florida Section ARES currently remains at a Level 3 Activation, as several ARES groups in the section are on standby for possible deployment by early to the  middle of next week.

Note:  The Section ARES Alert Level simply reflects the activation status of local ARES groups in the ARRL West Central Florida Section.  Each ARES groups activates at the request of their served agencies and or in accordance with their local ARES plan.

Section ARES Activation Levels:
Level 3:   One or more ARES groups on Standby for possible activation in one or more WCF Counties.
Level 2:  One or more WCF Section ARES Groups are activated.
Level 1:  All WCF Section ARES Groups are activated.

The following activations of the following ARES groups were at the requests of their respective Emergency Management agencies:

  • Hillsborough County ARES/RACES – Going to a Leve1 activation (full activation) on Monday 9/26/22.
  • Pinellas County ARES/ACS will be going to a Level 2 activation (partial activation) on Monday 9/26/22 and to Level 1 activation on Tuesday 9/27/22.
  • Pasco County ARES/RACES will be going to a Level 2 activation on Monday 9/26/22 and a Level 1 activation on Tuesday 9/27/22.

All the other ARES groups in the remainder of the ARRL West Central Florida Section are at a Level 3 activation for the time being.

All ARES, ACS, and CERT personnel are encouraged to continue to check each advisory issued by the National Hurricane Center in Miami and the Tropical Weather Outlook issued four times daily by the National Hurricane Center.  All ARES, ACS, and CERT personnel should bring to completion any personal preparedness activities very shortly and stay in communication with their respective leadership, in case of activation.  We have been reminded that we DO NOT SELF ACTIVATE.  Please wait for permission to activate from your respective chains of command.

This information is being posted in today’s bulletin as it is well worth repeating.  Arc Thames W4CPD has been designated as the liaison between all three of the ARRL Florida Section ARES programs and the Florida Division of Emergency Management.  Thames had the following message for all Florida ARES groups:  “Tropical Storm Ian has its eye set on somewhere in Florida mid-late next week. At this point, almost the entirety of the state is in the cone of uncertainty. I encourage you to you prepare your homes and families while there is time ahead of the storm. I also encourage all ARES and other communications teams across the state to prepare and test their equipment this weekend since there is so much uncertainty of the path of the storm.

I am actively in contact with the state ESF-2 team and have been asked to prepare volunteers for possible deployment to counties that may not have enough amateur radio volunteers. There are many counties that may end up with a significant need for amateur radio operators to staff shelters and augment local ARES or other communications teams. In preparation for this, if you would be willing to deploy to another county within the state for Ian, please complete this application at this website: https://forms.gle/oeyspzfhPnf9RDdQ6.

It is preferred that you have completed the AUXCOMM course (completion of the AUXCOMM Taskbook is not required) or your ARES Taskbook to level 2. Regardless of your completion of those items, if interested, please fill out the application as soon as possible. Please remember, at no time do we “self-deploy.” Any deployment notices will come either via myself or David Byrum from the State or possibly via your local agencies.

We will also need experienced net control stations that can operate an Emergency HF Net in support of the counties in the impacted areas. If you have a strong station that can transmit and receive well throughout the state, please complete this registration form – https://arrl-nfl.org/emncs/

In addition, we have come to the difficult decision to postpone the statewide exercise/SET that was planned for October 1. For those counties that had signed up, please keep your inject packets. We will announce the replacement date in the coming months.”

Bobby Graves KB5HAV, the Net Manager of the Hurricane Watch Net announced earlier today that the Hurricane Watch Net will not activate today, but an announcement will be made tomorrow, Monday September 25, by 1130 EDT as to when the Hurricane Watch Net will be activated.  The net frequencies are 14.325 KHz on 20 Meters during the day and 7268 KHz on 40 Meters at night, or both frequencies could be active at the same if band conditions warrant both frequencies to be activated.  Please leave these frequencies open for the time being and especially when these nets are active as they will be disseminating National Hurricane Center (NHC) bulletins, and coordinating the transmission of weather reports from the affected areas to the NHC.  For more information you may go to the Hurricane Watch Net website at https://www.hwn.org.

FORECAST DISCUSSION:

The following excerpt is from the Forecast Discussion issued at 1700 EDT today:

“The satellite presentation of Ian has improved this afternoon. The associated deep convection shows increased signs of organization, and the deep-layer shear appears to have diminished over the cyclone based on more extensive upper-level outflow noted in visible satellite imagery. An Air Force Hurricane Hunter aircraft found 850-mb peak flight level winds of 44 kt and several SFMR retrievals greater than 40 kt, while dropsonde data suggest the minimum pressure has not changed much since the previous flight. A blend of these data support an initial intensity of 40 kt for this advisory.

The aircraft data suggest the center could be re-forming slightly west of previous estimates, so the initial motion is an uncertain 265/14 kt. Ian is expected to move westward through early Sunday before turning northwestward around the southwestern periphery of a ridge to the north. A north-northwestward to northward motion is forecast on Monday and Tuesday as the center of Ian passes near or over the western tip of Cuba and emerges over the southeastern Gulf of Mexico. Overall, the westward trend in the track models continues, with the latest GFS on the far left side of the guidance envelope and the ECMWF on the right edge. The track forecast is still highly uncertain at days 4-5, with the GFS and ECMWF positions about 200 n mi apart by 96 h. There is significant spread noted even among the GFS ensemble members, with positions that range from the north-central Gulf of Mexico to the west coast of Florida. Hopefully, data collected from special radiosonde releases and a NOAA G-IV flight this evening will help better resolve the steering flow around Ian and the deep-layer trough that is forecast to be over the eastern U.S. early next week. The latest NHC track forecast is once again adjusted westward, and further adjustments may be needed given the increased uncertainty in the day 3-5 period.

Ian is expected to significantly strengthen over the next few days as it moves within a low shear environment over SSTs greater than 30 deg C in the northwestern Caribbean Sea. As the structure of the cyclone continues to improve and Ian develops an inner core, rapid intensification (RI) appears very likely. The SHIPS-RII probabilities continue to highlight this potential, with a 66 percent chance of a 65-kt intensity increase in 72 h. The NHC intensity forecast has been raised substantially through 96 h, and it now shows Ian reaching major hurricane strength by late Monday before it nears western Cuba. These changes closely follow the IVCN and HCCA consensus aids, although there remains guidance even higher than the current forecast. Ian is forecast to remain a major hurricane as it moves northward across the eastern Gulf of Mexico and approaches Florida. Environmental conditions could become less favorable late in the period due to southerly shear associated with the aforementioned trough, but Ian is expected to remain a largeand powerful hurricane through the period.”

SITUATION AND ACTIONS:

ARRL West Central Florida Section ARES remains at a Level 3 Activation, as several ARES groups in the section are on standby for possible deployment by the middle of next week.  A Level 3 Activation is a Standby status, when there is a possibility of one or more ARES groups in any of the ten counties of the ARRL West Central Florida Section being activated to provide services to their served agencies.

The low-level center has been decoupled from the deep convection for much of the day, but in recent satellite imagery it appears the center may be drawing closer to a more recent burst of convective activity. Unfortunately, earlier scatterometer data missed the center of the cyclone, and the satellite intensity estimates still range from 25-35 kt. The initial intensity is held at 30 kt for this advisory, and an Air Force Hurricane Hunter aircraft is on its way to investigate the system this evening.

The system is still moving west-northwestward at 290/13 kt, but it is expected to turn westward tonight and continue on that heading through Saturday as a ridge develops to its north. Then, a deep-layer trough over the eastern U.S. is forecast to erode the ridge into early next week. This should result in a turn toward the northwest and north-northwest while the cyclone passes near the Cayman Islands early Monday and approaches western Cuba Monday night. Once again, the global models have shifted westward this cycle during this period, and there remains increased track uncertainty late in the forecast period once the cyclone emerges into the southeastern Gulf of Mexico. The latest NHC track forecast has been adjusted westward from 48-120 h, and it lies near or slightly east of the latest track consensus aids.

Recent satellite trends suggest the cyclone may already be nearing a lower shear environment, and once that occurs, the atmospheric and oceanic conditions appear very conducive for strengthening through early next week. As the cyclone moves within a moist and unstable environment over sea-surface temperatures greater than 30 deg C, it is forecast to rapidly intensify over the northwestern Caribbean Sea and continue strengthening while it approaches western Cuba on Monday night. The very warm waters of the southeastern Gulf of Mexico should allow for more strengthening once it crosses Cuba, and the NHC forecast once again shows the system approaching the Florida peninsula as a major hurricane by the middle of next week.

Based on the latest forecast, a Hurricane Watch has been issued for the Cayman Islands, and a Tropical Storm Watch has been issued for Jamaica.”

SITUATION AND ACTIONS:

Due to the potential threat to the ARRL West Central Florida Section and the State of Florida, Mike Douglas W4MDD, Section Manager of the ARRL West Central Florida Section, in consultation with Christine Duez K4KJN, Section Emergency Coordinator, announced that ARRL West Central Florida Section ARES will go to a Level 3 Activation.  A Level 3 Activation is a Standby status, when there is a possibility of one or more ARES groups in any of the ten counties of the ARRL West Central Florida Section being activated to provide services to their served agencies.

Note:  The Section ARES Alert Level simply reflects the activation status of local ARES groups in the ARRL West Central Florida Section.  Each ARES groups activates at the request of their served agencies and or in accordance with their local ARES plan.

Several ARES groups are already on standby status in case they are requested to activate by their local Emergency Management agencies.  All ARES, ACS, and CERT personnel are encouraged to continue to check each advisory issued by the National Hurricane Center in Miami and the Tropical Weather Outlook issued four times daily by the National Hurricane Center.  All ARES, ACS, and CERT personnel should bring to completion any personal preparedness activities as soon as possible and stay in communication with their respective leadership, in case of activation.

WCF SECTION PRESS RELEASE #22-23

CHARLOTTE AMATEUR RADIO SOCIETY SCHEDULES WINLINK 2000 DRILL

The Charlotte Amateur Radio Society plans to conduct an emergency communications exercise to test WinLink Peer-to-Peer communications on Saturday, September 17, 2022 from 1000 until 1200.  This exercise is part of the Charlotte Amateur Radio Society’s long-term multi-part educational  program to ensure that radio amateurs in our area have a way to grow and practice the skills that may be used in a variety of emergency communications situations.

This exercise aims to evaluate our ability to pass digital traffic using WinLink Peer-to-Peer
communications through VARA FM.  We will have two control stations operating in Charlotte County. Our West County Control Station will operate WinLink on 144.300 MHz and our East County Control Station will operate WinLink in VARA FM on 144.330 MHz. For this exercise, questions may be directed over the WX4E linked repeater system on 146.745 (-) and 444.975 (+), both with a PL tone of 136.50.  Remember, this is a WinLink Peer-to-Peer contact.

Each participant will have three tasks during this exercise:  (1) Deliver a Field Situation Report to the local control station P2P – Locate the WinLink Template under Standard Templates / General Forms / Field Situation Report.  (2) After delivering your Field Situation Report, the Control Station will prepare an Emergency Bulletin to your WinLink address. They will need time to process your bulletin after receiving your Filed Station Report. Retrieve the current Emergency Bulletin from your local control station P2P.(3) Read and follow the instructions on the Emergency Bulletin.

Upon completion of the task listed above, each participant is free to secure their station.
Licensed Amateur radio operators from Charlotte County and the directly surrounding counties that are not CARS members are encouraged to visit the CARS website at http://carsfl.org for information about how they can help on the day of the event from their own radios.
