DEPRESSION GABRIELLE...LOCATED ABOUT 260 MILES SOUTH OF NANTUCKET
MASSACHUSETTS.

A BROAD AREA OF LOW PRESSURE...ASSOCIATED WITH A TROPICAL WAVE...IS
LOCATED ABOUT MIDWAY BETWEEN THE CAPE VERDE ISLANDS AND THE LESSER
ANTILLES AND IS ACCOMPANIED BY A LARGE AREA OF SHOWERS AND
THUNDERSTORMS.  THIS SYSTEM IS SLOWLY BECOMING BETTER ORGANIZED AND
COULD DEVELOP INTO A TROPICAL DEPRESSION WITHIN A DAY OR TWO AS IT
MOVES WESTWARD TO WEST-NORTHWESTWARD AT 10 TO 15 MPH.

SHOWER AND THUNDERSTORM ACTIVITY OVER THE LESSER ANTILLES AND THE
EXTREME EASTERN CARIBBEAN SEA IS ASSOCIATED WITH A TROPICAL WAVE.
SURFACE PRESSURES ARE NOT FALLING IN THE AREA...AND SIGNIFICANT
DEVELOPMENT OF THIS SYSTEM IS NOT ANTICIPATED AS IT MOVES
WEST-NORTHWESTWARD AT ABOUT 15 MPH.

SURFACE OBSERVATIONS INDICATE THAT A BROAD AREA OF LOW PRESSURE IS
LOCATED OVER THE WESTERN GULF OF MEXICO.  ALTHOUGH THE ASSOCIATED
CLOUDINESS AND THUNDERSTORMS ARE DISORGANIZED AT THIS TIME...
UPPER-LEVEL WINDS COULD BECOME A LITTLE MORE FAVORABLE FOR
DEVELOPMENT AS THE SYSTEM MOVES SLOWLY WESTWARD.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.
