STORM OPHELIA...LOCATED ABOUT 385 MILES EAST OF THE LEEWARD
ISLANDS...AND TROPICAL DEPRESSION SEVENTEEN...LOCATED ABOUT 305
MILES SOUTH OF THE SOUTHERNMOST CAPE VERDE ISLANDS.

AN ELONGATED LOW PRESSURE SYSTEM HAS DEVELOPED JUST NORTH OF THE
NORTHERN BAHAMAS...OR ABOUT 175 MILES EAST-SOUTHEAST OF CAPE
CANAVERAL FLORIDA. SATELLITE AND DOPPLER RADAR DATA INDICATE THAT
SHOWERS AND THUNDERSTORMS HAVE BECOME A LITTLE BETTER ORGANIZED...
AND SOME SLOW DEVELOPMENT OF THIS DISTURBANCE IS POSSIBLE DURING
THE NEXT DAY OR SO BEFORE UPPER-LEVEL WINDS BECOME UNFAVORABLE.
THIS SYSTEM HAS A MEDIUM CHANCE...30 PERCENT...OF BECOMING A
TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES GENERALLY
NORTHWARD AT 10 TO 15 MPH. REGARDLESS OF DEVELOPMENT...LOCALLY
HEAVY RAINFALL AND GUSTY WINDS WILL BE POSSIBLE OVER THE
NORTHWESTERN AND CENTRAL BAHAMAS THROUGH SUNDAY MORNING.

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