A large area of disturbed weather east of Puerto Rico has caught the attention of the NHC. This has been classified as sub-tropical and has a Dvorak rating of ST 1.5 ...25 kts. It is moving west and should reach Puerto Rico tomorrow. Models continue it west and west southwest passing to the south of Cuba later in the week. A more westward track would be necessary for it to bring some rainfall to south Florida but at this time that is not likely.

SPECIAL TROPICAL DISTURBANCE STATEMENT
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
500 PM EST SUN DEC 9 2007
AN AREA OF SHOWERS AND THUNDERSTORMS HAS BECOME BETTER ORGANIZED
TODAY ABOUT 550 MILES EAST-NORTHEAST OF PUERTO RICO...IN
ASSOCIATION WITH A SHARP SURFACE TROUGH AND A LARGE UPPER-LEVEL
LOW. THE SYSTEM IS ALREADY PRODUCING GALE FORCE WINDS...MAINLY TO
THE NORTH AND NORTHEAST OF THE MAIN AREA OF THUNDERSTORMS. THE
SURFACE TROUGH HAS BEEN MOVING WESTWARD AT ABOUT 15 TO 20 MPH...AND
THIS GENERAL MOTION IS EXPECTED TO CONTINUE OVER THE NEXT DAY OR
TWO. WATER TEMPERATURES ARE STILL WARM ENOUGH IN THIS AREA TO
SUPPORT TROPICAL CYCLONE FORMATION...AND UPPER-LEVEL WINDS ARE NOT
ESPECIALLY PROHIBITIVE FOR DEVELOPMENT. THIS SYSTEM HAS THE
POTENTIAL TO BECOME A TROPICAL OR SUBTROPICAL STORM DURING THE NEXT
24 HOURS...AND INTERESTS IN THE NORTHERN LEEWARD ISLANDS...THE
VIRGIN ISLANDS...PUERTO RICO...HISPANIOLA...AND THE EASTERN BAHAMAS
SHOULD MONITOR THE PROGRESS OF THIS SYSTEM.
FURTHER SPECIAL TROPICAL DISTURBANCE STATEMENTS WILL BE ISSUED AS
NECESSARY. FOR INFORMATION SPECIFIC TO YOUR AREA...CONSULT

FAVORABLE FOR DEVELOPMENT...BUT A TROPICAL OR SUBTROPICAL CYCLONE
COULD STILL FORM DURING THE NEXT 24 HOURS. REGARDLESS OF FURTHER

FURTHER...IT COULD PRODUCE HEAVY SQUALLS AND GUSTY WINDS OF NEAR
GALE FORCE ACROSS THE VIRGIN ISLANDS AND PUERTO RICO LATER TODAY
AND TONIGHT AS IT MOVES WESTWARD OR WEST-SOUTHWESTWARD AT ABOUT 20
MPH. HEAVY RAINS OVER PUERTO RICO AND HISPANIOLA COULD CAUSE

If the NHC track shown below verifies, 94L should be near the Yucatan Channel late this week. While conditions in the Caribbean are hostile for development 94L could still be a good rainmaker if the approaching front shown in the pic below grabs 94L and turns it north and northeast into Florida. It's a long shot and we have not been lucky when it comes to getting rain. One can only hope.
