1. SURFACE OBSERVATIONS INDICATE THE LARGE LOW PRESSURE SYSTEM LOCATED
NEAR THE NORTHEASTERN TIP OF THE YUCATAN PENINSULA IS GRADUALLY
BECOMING BETTER DEFINED. SHOWERS AND THUNDERSTORMS HAVE ALSO
INCREASED AND BECOME BETTER ORGANIZED NEAR THE SURFACE CENTER
DURING THE PAST SEVERAL HOURS. ADDITIONALLY...WINDS TO NEAR
TROPICAL STORM FORCE ARE OCCURRING IN THE YUCATAN CHANNEL...OVER
THE EXTREME SOUTHEASTERN GULF OF MEXICO...AND OVER THE WESTERN
STRAITS OF FLORIDA. UPPER-LEVEL WINDS ARE EXPECTED TO BE MARGINALLY
CONDUCIVE FOR DEVELOPMENT DURING THE NEXT DAY OR SO BEFORE BECOMING
UNFAVORABLE AFTER THAT. ALTHOUGH THIS LARGE DISTURBANCE IS
INTERACTING WITH THE YUCATAN PENINSULA...SOME GRADUAL DEVELOPMENT
IS STILL POSSIBLE AS THE LOW MOVES TOWARD THE NORTH OR NORTHWEST AT
5 TO 10 MPH. THIS SYSTEM HAS A HIGH CHANCE...
60 PERCENT...OF
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS. REGARDLESS OF
DEVELOPMENT...LOCALLY HEAVY RAINFALL AND GUSTY WINDS ARE EXPECTED
OVER THE YUCATAN PENINSULA...WESTERN CUBA...THE FLORIDA KEYS...AND
SOUTH FLORIDA DURING THE NEXT COUPLE OF DAYS.
AN AIR FORCE RESERVE
RECONNAISSANCE AIRCRAFT IS SCHEDULED TO INVESTIGATE THE LOW THIS
AFTERNOON...IF NECESSARY.
