MODEL PREFERENCE: GFS/WW3 WITH HIGH CONFIDENCE.

A TROUGH IN THE WEST-CENTRAL GULF ALONG 91W WILL DRIFT SLOWLY W

GULF FROM E TO W BEHIND THE TROUGH. NORTHERN PART OF A TROPICAL 
WAVE MOVING THROUGH THE STRAITS OF FLORIDA WILL MOVE INTO FAR SE 
PORTION LATER TONIGHT. AN UPPER LOW CENTERED NEAR SOUTH FLORIDA 
WILL ALSO MOVE INTO THE SE GULF TONIGHT. ACTIVE TSTM ACTIVITY IS 
POSSIBLE OVERNIGHT W OF THE FLORIDA KEYS. LIGHT TO MODERATE E-SE 
WINDS WILL PREVAIL ACROSS THE REGION SAT THROUGH WED.

...CARIBBEAN SEA AND TROPICAL N ATLANTIC...

TO MODERATE WINDS PREVAIL OVER MOST OF THE AREA N OF 22N...WHILE 
MODERATE TO FRESH TRADES ARE FOUND S OF 22N...PRIMARILY DUE TO 
THE NORTHERN PORTION OF A TROPICAL WAVE OVER W CUBA. SEAS ARE 3
