GULF OF MEXICO...
HIGH PRES CENTERED OVER MISSISSIPPI EXTENDS A RIDGE ACROSS THE 
ENTIRE GULF WATERS. WINDS AND SEAS ARE BEGINNING TO DIMINISH 
ACROSS THE REGION PER THE 1504 UTC ASCAT PASS THAT SHOWED WINDS 
OF 15 TO 20 KT OVER THE EASTERN GULF. THIS TREND WILL CONTINUE 
THROUGH TONIGHT INTO FRI WITH WINDS BELOW 20 KT AND SEAS 
SUBSIDING BELOW 8 FT. HOWEVER...HIGH PRESSURE WILL CONTINUE TO 
BUILD N OF THE AREA FRI THROUGH SUN ALLOWING AGAIN SOME INCREASE 
IN WINDS AND SEAS ACROSS THE AREA. SE RETURN FLOW IS EXPECTED W 
OF 95W BY MON AND WILL PERSIST ON TUE. 

CARIBBEAN SEA AND TROPICAL N ATLC...
A STATIONARY FRONT OVER THE FAR W CARIBBEAN WILL DISSIPATE FROM 
WESTERN CUBA TO THE GULF OF HONDURAS THROUGH TONIGHT. THE MOST 
RECENT ASCAT PASS INDICATED NLY OF 20 KT BEHIND THE FRONT. AS 
HIGH PRES BUILDS OVER THE SE CONUS...EXPECT NLY WINDS OF 20 KT

LATE FRI. 

MEANWHILE...A WEAKENING UPPER LEVEL LOW CURRENTLY NEAR 28N56W 
WILL CONTINUE TO SHIFT S AND THEN WEST AROUND THE PERIPHERY OF 
AN UPPER LEVEL HIGH. IN RESPONSE TO THIS FEATURE...A BROAD 
SECOND TROUGH IS EXPECTED TO DRIFT WESTWARD INTO THE TROPICAL N 
ATLC WATERS THIS UPCOMING WEEKEND...POSSIBLY REACHING THE SW N 
ATLC WATERS EARLY NEXT WEEK. EXPECT WINDS OF 20 TO 25 KT AND 
BUILDING SEAS IN THE 8 TO 12 FT RANGE DUE TO THE TIGHT PRES 
GRADIENT BETWEEN THIS TROUGH AND A HIGH PRES N OF THE FORECAST 
AREA.

BELT OF NE TO E WINDS OF 20 KT WILL CONTINUE TO AFFECT THE 
WATERS S OF 26N AND E OF THE BAHAMAS WITH SEAS TO AROUND 10 FT.
