TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
800 PM EDT TUE JUL 31 2012

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

1. SHOWERS AND THUNDERSTORMS HAVE BECOME A LITTLE MORE CONCENTRATED 
NEAR THE CENTER OF A LOW PRESSURE SYSTEM LOCATED ABOUT 1150 MILES
EAST-SOUTHEAST OF THE WINDWARD ISLANDS. ENVIRONMENTAL CONDITIONS
ARE AT LEAST MARGINALLY CONDUCIVE FOR SOME GRADUAL DEVELOPMENT OF
THIS DISTURBANCE OVER THE NEXT FEW DAYS AS IT MOVES WESTWARD AT 
15 TO 20 MPH. THIS SYSTEM HAS A MEDIUM CHANCE...50 PERCENT...OF
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS 

2. A WESTWARD-MOVING TROPICAL WAVE OVER THE CENTRAL CARIBBEAN SEA IS
PRODUCING WIDESPREAD CLOUDINESS AND THUNDERSTORMS FROM HISPANIOLA
EASTWARD FOR SEVERAL HUNDRED MILES. THERE ARE NO SIGNS OF A SURFACE
CIRCULATION...AND UPPER-LEVEL WINDS ARE NOT FAVORABLE FOR ANY
SIGNIFICANT DEVELOPMENT TO OCCUR. THIS SYSTEM HAS A LOW CHANCE...
NEAR 0 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 
48 HOURS. HOWEVER...LOCALLY HEAVY HEAVY RAINFALL AND GUSTY WINDS
ASSOCIATED WITH THIS WAVE WILL SPREAD ACROSS HISPANIOLA...EASTERN
CUBA...AND THE SOUTHEASTERN BAHAMAS DURING THE NEXT DAY OR TWO.

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