A WELL-DEFINED LOW PRESSURE SYSTEM IS LOCATED ABOUT 100 MILES EAST

CYCLONE DURING THE NEXT 48 HOURS...AND A MEDIUM CHANCE...50
PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 5 DAYS
WHILE IT MOVES WESTWARD AT 10 TO 15 MPH ACROSS THE CARIBBEAN SEA.
REGARDLESS OF WHETHER OR NOT A TROPICAL CYCLONE FORMS...LOCALLY
HEAVY RAINFALL AND STRONG GUSTY WINDS ARE EXPECTED TO AFFECT
PORTIONS OF THE LESSER ANTILLES TODAY THROUGH MONDAY.

OTHER SYSTEMS WITH FORMATION POTENTIAL BEYOND 48 HOURS...
