TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
200 AM EDT WED JUL 21 2010

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

A STRONG TROPICAL WAVE...LOCATED NEAR THE EASTERN DOMINICAN REPUBLIC
AND EXTENDING NORTHWARD OVER THE ATLANTIC FOR A FEW HUNDRED
MILES...IS PRODUCING A LARGE AREA OF SHOWERS AND THUNDERSTORMS FROM
THE NORTHERN LEEWARD ISLANDS WESTWARD TO HISPANIOLA...AND OVER THE
ADJACENT WATERS OF THE ATLANTIC AND NORTHEASTERN CARIBBEAN SEA.
ALTHOUGH A CLOSED SURFACE CIRCULATION HAS NOT YET DEVELOPED...
ENVIRONMENTAL CONDITIONS ARE EXPECTED TO BECOME MORE CONDUCIVE FOR
TROPICAL CYCLONE FORMATION AS THE SYSTEM MOVES WEST-NORTHWESTWARD
AT ABOUT 10 MPH DURING THE NEXT DAY OR SO. THERE IS A HIGH
CHANCE...70 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL DEPRESSION
OR A TROPICAL STORM DURING THE NEXT 48 HOURS. REGARDLESS OF
DEVELOPMENT...LOCALLY HEAVY RAINFALL AND GUSTY WINDS WILL CONTINUE
TO AFFECT THE VIRGIN ISLANDS AND PUERTO RICO...AND LIKELY AFFECT
THE DOMINICAN REPUBLIC...HAITI...EASTERN CUBA...THE TURKS AND
CAICOS ISLANDS...AND THE BAHAMAS DURING THE NEXT COUPLE OF DAYS.
THE HEAVY RAINS COULD CAUSE LIFE-THREATENING FLASH FLOODS AND MUD
SLIDES IN MOUNTAINOUS AREAS.

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