NEW SECTION MANAGER ELECTED FOR THE ARRL WEST CENTRAL FLORIDA SECTION

Mike Douglas W4MDD, the ARRL Affiliated Club Coordinator for the ARRL West Central Florida Section, has been elected as the 4th Section Manager for the ARRL West Central Florida Section.   The nomination period ended on Friday September 4th, and Douglas was the only candidate to submit a nomination form and to be received by ARRL HQ by the end of the nomination period.  Darrell Davis KT4WX, the current Section Manager for the ARRL West Central Florida Section decided not to seek re-election for the 2020-2021 term.  Davis made the following comment concerning the election of Douglas as the new Section Manager, “After praying and thinking about it, I decided not to seek re-election as circumstances in my personal life have changed over the last two years.  I appreciate all of the support that I have received from all of you and I am not ‘riding off into the sunset’.  My role in the ARRL West Central Florida Section will simply be in a supportive role and different.  Mike will do a fine job as our new Section Manager and has traveled all over the ARRL West Central Florida Section with me over the last three years and has gotten to know many of you.  Please give him the same support you have given me.”

Douglas has been a licensed radio amateur since 1991, first holding the callsign of N9OEV, and was previously almost a lifelong resident of the Chicago, Illinois area.  Douglas relocated to Florida in the summer of 2016, following his retirement, and obtained his current callsign of W4MDD.  Douglas became an Assistant Emergency Coordinator with Hardee County ARES in late 2016 after coming to Hardee County from the east coast of Florida.  Douglas then became the ARRL Affiliated Club Coordinator in late 2017.  Douglas in his professional career was commercial tour bus driver, was in commercial bus sales, and for 20 years of his career was with Educational Tours, a tour bus company devoted to providing tours for school age children of educational sites in places all over the United States.

Douglas’ term as Section Manager will begin on January 1, 2021.  Davis has served as Section Manager since January 1, 2015 and his current term as Section Manager will end on December 31, 2020.

HURRICANE LAURA – 1800 EDT – 8/25/20

Tropical Depression Marco, which was the near the Louisiana coastline yesterday lost nearly all of its convection and showed signs of opening up into an elongated area of low pressure.  As a result the National Hurricane Center issued its last advisory at 0500 EDT today on Tropical Depression Marco as the cyclone no longer meet the criteria of a tropical cyclone.  Now Hurricane Laura is once again alone in the Gulf of Mexico.

SUMMARY OF 400 PM CDT…2100 UTC…INFORMATION

LOCATION…24.7N 88.3W
ABOUT 480 MI…770 KM SE OF LAKE CHARLES LOUISIANA
ABOUT 510 MI…820 KM SE OF GALVESTON TEXAS
MAXIMUM SUSTAINED WINDS…80 MPH…130 KM/H
PRESENT MOVEMENT…WNW OR 300 DEGREES AT 17 MPH…28 KM/H
MINIMUM CENTRAL PRESSURE…990 MB…29.24 INCHES

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for…
* San Luis Pass Texas to the Mouth of the Mississippi River

A Hurricane Warning is in effect for…
* San Luis Pass Texas to Intracoastal City Louisiana

A Tropical Storm Warning is in effect for…
* Sargent Texas to San Luis Pass
* East of Intracoastal City Louisiana to the Mouth of the
Mississippi River

A Storm Surge Watch is in effect for…
* Freeport Texas to San Luis Pass
* Mouth of the Mississippi River to Ocean Springs Mississippi
* Lake Pontchartrain, Lake Maurepas, and Lake Borgne

A Hurricane Watch is in effect for…
* East of Intracoastal City to west of Morgan City Louisiana

DISCUSSION:

The following excerpts are from the Forecast Discussion issued at 1700 EDT today, “Satellite imagery shows some changes in the convective pattern of Laura since the last advisory. The ragged central dense overcast seen earlier has been replaced by a curved convective band that
wraps almost all the way around a cloud-filled banding-type eve. One possible reason for this change is that the imagery also suggests a
tongue of dry air is trying to entrain into the cyclone just west of the central convection. Aircraft data received after the last advisory did not show any fall in the central pressure, but did have high enough flight-level and SFMR winds to justify nudging the initial intensity up to 70 kt.

The initial motion is now west-northwestward or 300/15 kt. There is no change in the forecast philosophy since the last advisory. The hurricane is currently on the south side of a large-deep layer ridge over the southeastern United States, and it is moving toward a break in the ridge caused by mid- to -upper-level troughing over Texas and the southern Great Plains. The current and forecast synoptic pattern should steer Laura west-northwestward this evening, followed by a turn toward the northwest tonight and toward the north by Wednesday night and Thursday. This will result in the hurricane making landfall in the area of southwestern Louisiana or the upper Texas coast late Wednesday night or Thursday morning. The new forecast track has a slight eastward nudge during the first 12-24 h, but the landfall position is almost unchanged from that of the previous forecast. It should the be noted that the current forecast track lies to the east of the ECMWF and UKMET models, so it is still
possible that the forecast track could nudge westward in later advisories. After landfall, Laura is expected to recurve into the westerlies and move eastward through the Tennessee Valley and the mid-Atlantic States before reaching the Atlantic in about 120 h.”

SITUATION AND ACTIONS:

At the present time all Tropical Storm Watches and Tropical Storm Warnings for the entire State of Florida have been discontinued due to Hurricane Laura heading away from the State of Florida.  Hurricane Laura will make landfall most likely in either the eastern Texas or western Louisiana coastline late tomorrow evening or early on Thursday morning.

Everyone should continue or resume their normal monitoring of the latest Tropical Weather Outlook issued four times a day by the National Hurricane Center and continue to monitor the latest advisories on Hurricane Laura.  The Hurricane Watch Net will activate tomorrow morning on 14325 KHz and or 7268 KHz to receive weather reports of interest to the National Hurricane Center and relay of any emergency or priority traffic.  For more information go to the following ARRL News Release:  http://www.arrl.org/news/hurricane-watch-net-firms-up-wednesday-activation-plans.

DISCUSSION

The following is excerpts from the Forecast Discussion at 1700 EDT, “The satellite presentation of the tropical storm has improved
somewhat with deep convection remaining over the center, and an increase in banding over the southeastern portion of the circulation. Earlier aircraft and scatterometer data, however, indicated that there has been little change in strength today, and the initial intensity remains 50 kt. These observations have shown the the stronger winds are located in the convective band well east and southeast of the center, and that the system currently lacks an inner core. This is likely the reason that Laura has not been able to strengthen while it has moved over water today. Theaircraft also reported a fairly stable minimum pressure of 1001-1003 mb during its mission this morning and early afternoon.

The intensity forecast philosophy remains the same as the previous advisory. Once Laura moves over the southeastern Gulf of Mexico tonight, a combination of warm sea surface temperatures and low vertical wind shear should allow for steady strengthening. The latest iterations of the global and regional hurricane models continue to show significant deepening while Laura traverses the Gulf of Mexico, and a period or rapid strengthening is possible once an inner core is able to organize. The statistical guidance is again on the lower side of the intensity forecast envelope while the HWRF and CTCI models bringing Laura to major hurricane strength. The NHC intensity forecast is again between these
solutions and is close to the consensus aids.

The initial motion estimate is 290/16 kt. A deep-layer ridge over the western Atlantic is expected to build westward during the next day or so. By early Wednesday, a mid- to upper-level trough over the south-central United States is forecast to erode the western portion of the ridge, which should cause Laura to turn northwestward and then northward toward the northwestern Gulf coast. After landfall, Laura or its remnants are expected to become embedded in the mid-latitude westerlies and recurve over the eastern U.S.on days 4 and 5.”

SITUATION AND ACTIONS:

At the present time Tropical Storm Warnings are in effect for the Florida Keys from Craig Key to Key West and the Dry Tortugas in the State of Florida as Laura is due to pass close to the Florida Keys on Tuesday before heading in the the central and western Gulf of Mexico away from the State of Florida for eventual landfall most likely on the western coast of Louisiana on Thursday.

As of press time, there are no requests for activation from any of our served agencies in the ten counties of the ARRL West Central Florida Section.  Manatee County ARES returned to a no activation status from a Level 3 activation (stand by) due to any requests for assistance not being anticipated for this incident.  All ARES, ACS, and CERT personnel should continue to monitor the latest National Hurricane Center advisories on Tropical Storm Laura while the storm is in close proximity to the State of Florida.

TROPICAL STORM LAURA AND HURRICANE MARCO – 1800 EDT – 8/23/20

Since our last WCF SECTION SPECIAL BULLETIN yesterday Tropical Storm Marco entered the Gulf of Mexico and has become a category 1 hurricane.  There is a good possibility that by Tuesday we will have one hurricane and one tropical storm in the Gulf of Mexico at the same time, which is somewhat rare.  There is a possibility that Tropical Storm Laura could obtain category 1 hurricane status as Hurricane Marco is making landfall on the northern Gulf coast, which will allow us to see two hurricanes in the Gulf of Mexico at the same time, which has not been seen since modern records have been kept for over the past 100 years.   Information on Hurricane Marco has been included for information purposes only.

DISCUSSION:

The following are excerpts from the Forecast Discussion of Tropical Storm Laura:

“Satellite imagery and radar data from eastern Cuba show that the center of Laura has been moving over water between Haiti and eastern Cuba this afternoon. There has been a recent uptick in convection near the center and the radar imagery has shown an increase in banding. An Air Force reconnaissance aircraft investigating Laura this afternoon has reported a minimum pressure that has fallen to around 1000 mb, and winds to support an intensity of 50 kt. The plane very recently found a small area of stronger flight-level winds, but these winds may be associated with mesocyclone, and not representative of the large scale circulation.

Laura continues to move briskly west-northwestward or 285/18 kt. The track forecast reasoning remains the same as the previous advisory. Laura should continue to move west-northwestward to the south of a deep-layer ridge that is forecast to build westward across Florida and the eastern Gulf of Mexico during the next day or two. The track guidance has continued to edge southward for the portion of the forecast near Cuba, and the NHC forecast has again been moved in that direction. Laura should continue moving west-northwestward over the southeastern Gulf on Tuesday, but a turn toward the northwest is expected Tuesday night as the cyclone nears the western portion of the ridge. A northwestward to north-northwestward motion should then continue around the western portion of the ridge until the cyclone reaches the northwestern Gulf coast. The latest run of the ECMWF has shifted significantly eastward, however its ensemble mean and many of the stronger ensemble members remain farther west as a stronger cyclone is likely to be steered more westward by the deep-layer ridge. The GFS, UKMET, and HWRF remain close to the previous NHC track, so little change was made to the official forecast was made after 48 hours.”

SITUATION AND ACTIONS:

At the present time there are no Tropical Storm Warnings for the State of Florida.  There are Tropical Storm Watches in effect for the Florida Keys from Craig Key to Key West and the Dry Tortugas.

As of press time, only one county in the ARRL West Central Florida Section has an ARES group on a Level 3 activation, which is a stand by mode:  Manatee County. As of press time, there are no other ARES groups on any activation level.  All ARES, ACS, and CERT personnel should continue to monitor the latest National Hurricane Center advisories on Tropical Storm Laura while the storm is in close proximity to the State of Florida.

DISCUSSION

The following excerpts are from the Forecast Discussion issued at 1700 EDT on Tropical Storm Laura, “A couple of hours ago an observing site on the southeast coast of Puerto Rico, Las Mareas, reported sustained winds of 52 kt. These winds were apparently associated with a mesocyclone embedded within the larger-scale circulation and not representative of the intensity of the tropical storm. Scatterometer data and WSR-88D Doppler velocities from San Juan support an intensity of 45 kt. Since the center should be moving over land for the next 48 hours or so, no additional intensification is anticipated until Monday night when the center moves over the southeastern Gulf of Mexico. Over warm waters, with anticipated weak vertical shear, and anticyclonic flow aloft, Laura will likely strengthen into a hurricane before it reaches the northern Gulf of Mexico coast. The NHC intensity forecast is close to the multi-model consensus, but given the possibility of a favorable upper-air  environment over the Gulf, this forecast could be conservative. At this time it does not seem likely that Marco, which is forecast to make landfall on the north-central Gulf coast a day or two earlier than Laura, should have much of an influence on the latter system.

Center locations from earlier scatterometer data, low-cloud motions, and Dvorak fixes from both TAFB and SAB, give a motion of about 280/16 kt. Laura should move west-northwestward along the southern side of a mid-tropospheric anticyclone centered near the southeastern U.S. coast through 72 hours. Then, the cyclone is expected to turn northwestward to northward on the western side of the high. The official track forecast is on the right side of the track guidance suite.”

SITUATION AND ACTIONS:

At the present time there are no Tropical Storm Warnings for the State of Florida.  There are Tropical Storm Watches in effect for the Florida Keys and Florida Bay only.  This watch will no doubt be upgraded to a Tropical Storm Warning as Laura approaches the Florida Keys.

As of press time, only one county in the ARRL West Central Florida Section has an ARES group on a Level 3 activation, which is a stand by mode:  Manatee County. As of press time, there are no other ARES groups on any activation level.  All ARES, ACS, and CERT personnel should continue to monitor the latest National Hurricane Center advisories on Tropical Storm Laura while the storm is in close proximity to the State of Florida.

TROPICAL STORM ISAIAS – 1800 EDT – 8/03/20

The following is the latest advisory on Tropical Storm Isaias.  Isaias has remained a strong tropical storm since last on Saturday due to 30 MPH wind shear.  Isaias is expected to remain a strong Tropical Storm and regain status as a Category 1 hurricane, due to a change in the direction of the wind shear,  before making landfall later this evening near the border between South Carolina and North Carolina.  All Tropical Storm watches and warnings were discontinued for the entire State of Florida at 1100 EDT earlier today.

SUMMARY OF ADVISORY ON TROPICAL STORM ISAIAS AS OF 500 PM EDT…2100 UTC

LOCATION…32.0N 79.4W
ABOUT 60 MI…100 KM SSE OF CHARLESTON SOUTH CAROLINA
ABOUT 120 MI…195 KM SSW OF MYRTLE BEACH SOUTH CAROLINA
MAXIMUM SUSTAINED WINDS…70 MPH…110 KM/H
PRESENT MOVEMENT…NNE OR 15 DEGREES AT 16 MPH…26 KM/H

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for…
* Edisto Beach South Carolina to Cape Fear North Carolina
* Pamlico and Albemarle Sounds, including the Neuse and Pamlico
Rivers
* Oregon Inlet North Carolina to the North Carolina/Virginia border

A Storm Surge Watch is in effect for…
* Cape Fear to Oregon Inlet North Carolina

* Chesapeake Bay
* Tidal Potomac River
* Delaware Bay
* Long Island and Long Island Sound
* Martha’s Vineyard, Nantucket, and Block Island

A Tropical Storm Watch is in effect for…
* North of Stonington to Eastport Maine

DISCUSSION

The following excerpts are from the Forecast Discussion issued at 1700 EDT on Tropical Storm Isaias, “Isaias is now moving north-northeastward 015/14 kt. The new NHC model guidance remains in excellent agreement on Isaias continuing to gradually accelerate north-northeastward to northeastward for the next 36 hours ahead of a powerful deep-layer trough and associated cold front. The cyclone should make landfall later this evening near the South Carolina-North Carolina border, and then accelerate north-northeastward at 25-30 kt across eastern North Carolina early Tuesday, eastern Virginia and the Delmarva peninsula Tuesday afternoon, and into New England Tuesday night into early
Wednesday. The new NHC track forecast is just an update and extension of the previous advisory track, and lies very close to a blend of the tightly packed multi-model consensus aids TVCA, GFEX, TVCX, and NOAA-HCCA.

Satellite animation and special 1800Z upper-air soundings indicate that the vertical shear across Isaias has weakened and has also become more southwesterly, which better aligns with the forecast track. Given this and the improved structure of the system, Isaias is still expected to strengthen and regain hurricane status before making landfall, and most of the intensity guidance shows a 60-65 kt system at that time. It should be emphasized that there is little difference between a strong tropical storm or a category 1 hurricane in terms of impacts.

After landfall, Isaias is forecast to only slowly weaken due to interaction with an unusually strong 100-120 kt jetstream. The expected strong baroclinic forcing will keep Isaias’ circulation intact and also produce very strong wind gusts along the mid-Atlantic coast tomorrow. As a result, the gust factors at 24-48 h have been increased above the standard 20 percent in the Forecast/Advisory (TCMAT4). The cyclone is forecast to be absorbed by a larger extratropical low over Canada in 3-4 days.”

SITUATION AND ACTIONS:

All tropical storm watches, tropical storm warnings, hurricane watches, or hurricane warnings have been discontinued for the entire State of Florida as of 1100 EDT today.   Just continue to stay closely tuned to the any advisories that are issued on Tropical Storm Isaial and the Topical Weather Outlook issued four times daily by the National Hurricane Center in Miami.
