Development may take awhile, but models do like this feature further into the Caribbean...

A VIGOROUS TROPICAL WAVE LOCATED OVER THE TROPICAL ATLANTIC
ABOUT 1000 MILES EAST-SOUTHEAST OF THE WINDWARD ISLANDS IS PRODUCING
A LARGE AREA OF SHOWERS AND THUNDERSTORMS. ENVIRONMENTAL
CONDITIONS APPEAR FAVORABLE FOR SOME SLOW DEVELOPMENT OF THIS
SYSTEM DURING THE NEXT COUPLE OF DAYS. THERE IS A LOW CHANCE...20
PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS AS IT MOVES WESTWARD OR WEST-NORTHWESTWARD AT 15 TO
20 MPH.

A VIGOROUS TROPICAL WAVE LOCATED OVER THE TROPICAL ATLANTIC ABOUT
850 MILES EAST-SOUTHEAST OF THE WINDWARD ISLANDS IS PRODUCING A
LARGE AREA OF SHOWERS AND THUNDERSTORMS. THIS SYSTEM HAS BECOME
BETTER ORGANIZED TODAY...AND ENVIRONMENTAL CONDITIONS APPEAR TO BE
FAVORABLE FOR SOME SLOW DEVELOPMENT OF THIS DISTURBANCE DURING THE
NEXT COUPLE OF DAYS. THERE IS A MEDIUM CHANCE...30 PERCENT...OF
THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS
IT MOVES WESTWARD OR WEST-NORTHWESTWARD AT 15 TO 20 MPH.

A VIGOROUS TROPICAL WAVE LOCATED OVER THE TROPICAL ATLANTIC ABOUT
725 MILES EAST-SOUTHEAST OF THE WINDWARD ISLANDS IS PRODUCING A
LARGE AREA OF SHOWERS AND THUNDERSTORMS. THIS SYSTEM CONTINUES TO
SHOW SIGNS OF ORGANIZATION...AND ENVIRONMENTAL CONDITIONS APPEAR
TO BE FAVORABLE FOR GRADUAL DEVELOPMENT OF THIS DISTURBANCE
DURING THE NEXT COUPLE OF DAYS. THERE IS A MEDIUM CHANCE...50
PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS AS IT MOVES WESTWARD OR WEST-NORTHWESTWARD AT 15 TO
20 MPH. REGARDLESS OF DEVELOPMENT...THIS SYSTEM IS EXPECTED TO
BRING LOCALLY HEAVY RAINFALL AND STRONG GUSTY WINDS TO THE WINDWARD
ISLANDS...VENEZUELA...AND NORTHERN PORTIONS OF GUYANA DURING THE
NEXT COUPLE OF DAYS.

91L looks very impressive for this time of the year. If it enters the Caribbean, it will likely develop into Tomas, which would be the 19th storm of the season and it is not over yet. I think we could enter the Greek letters.

A STRONG TROPICAL WAVE LOCATED ABOUT 360 MILES EAST-SOUTHEAST OF THE
SOUTHERN WINDWARD ISLANDS HAS BECOME MUCH BETTER ORGANIZED THIS
MORNING...AND ENVIRONMENTAL CONDITIONS ARE CONDUCIVE FOR A TROPICAL
DEPRESSION OR A TROPICAL STORM TO FORM DURING THE NEXT DAY OR SO.
THERE IS A HIGH CHANCE...80 PERCENT...OF THIS DISTURBANCE BECOMING
A TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES
WEST-NORTHWESTWARD AT 15 TO 20 MPH. REGARDLESS OF DEVELOPMENT...
THIS SYSTEM IS EXPECTED TO BRING LOCALLY HEAVY RAINFALL AND STRONG
GUSTY WINDS TO THE WINDWARD ISLANDS AND NORTHERN PORTIONS OF
VENEZUELA DURING THE NEXT COUPLE OF DAYS. AN AIR FORCE RESERVE UNIT
RECONNAISSANCE AIRCRAFT IS SCHEDULED TO INVESTIGATE THE DISTURBANCE
THIS AFTERNOON.

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...
THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON TROPICAL
STORM SHARY...LOCATED ABOUT 155 MILES SOUTH-SOUTHWEST OF BERMUDA.
A STRONG TROPICAL WAVE...ACCOMPANIED BY A DEVELOPING LOW PRESSURE
SYSTEM...IS LOCATED ABOUT 225 MILES SOUTHEAST OF BARBADOS. DATA
FROM AN AIR FORCE RESERVE RECONNAISSANCE AIRCRAFT INVESTIGATING THE
SYSTEM THIS AFTERNOON INDICATES A CLOSED SURFACE CIRCULATION WITH
WINDS TO TROPICAL-STORM-FORCE IS FORMING. IF THIS DEVELOPMENT TREND
CONTINUES...THEN ADVISORIES WILL BE INITIATED ON TROPICAL STORM
TOMAS AT 5 PM AST...2100 UTC. TROPICAL STORM WARNINGS WOULD ALSO
THEN BE REQUIRED FOR PORTIONS OF THE WINDWARD ISLANDS. THERE IS A
HIGH CHANCE...NEAR 100 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES WEST-NORTHWESTWARD AT
15 TO 20 MPH.
