TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
200 AM EDT TUE JUL 20 2010

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

A VIGOROUS TROPICAL WAVE LOCATED OVER PUERTO RICO AND THE VIRGIN
ISLANDS CONTINUES TO PRODUCE WIDESPREAD CLOUDINESS AND
THUNDERSTORMS ACROSS THE NORTHERN LEEWARD ISLANDS...THE VIRGIN
ISLANDS...PUERTO RICO...AND ADJACENT ATLANTIC AND NORTHEASTERN
CARIBBEAN WATERS. ALTHOUGH SURFACE PRESSURES ARE NOT FALLING
SIGNIFICANTLY OVER THE AREA...RECENT UPPER-AIR DATA INDICATE THE
SYSTEM IS BECOMING BETTER ORGANIZED IN THE MIDDLE AND UPPER LEVELS
OF THE ATMOSPHERE. THERE IS A MEDIUM CHANCE...30 PERCENT...OF THIS
SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS THE
DISTURBANCE MOVES WEST-NORTHWESTWARD AT 5 TO 10 MPH. REGARDLESS OF
DEVELOPMENT... LOCALLY HEAVY RAINFALL AND GUSTY WINDS OF 30 TO 40
MPH COULD AFFECT THE NORTHERN LEEWARD ISLANDS...THE VIRGIN
ISLANDS...PUERTO RICO...THE DOMINICAN REPUBLIC...HAITI...EASTERN
CUBA...THE TURKS AND CAICOS ISLANDS...AND THE SOUTHEASTERN BAHAMAS
DURING THE NEXT COUPLE OF DAYS. RAINFALL TOTALS OF MORE THAN 5
INCHES HAVE ALREADY BEEN REPORTED ACROSS PORTIONS OF THE VIRGIN
ISLANDS AND PUERTO RICO...AND ADDITIONAL HEAVY RAINFALL COULD CAUSE
LOCALIZED FLOODS AND MUD SLIDES...ESPECIALLY OVER MOUNTAINOUS
TERRAIN.

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