HIGH PRES RIDGE OVER MUCH OF THE AREA WILL MOVE EASTWARD THROUGH
MON ALLOWING SOUTHERLY RETURN FLOW TO SET UP ACROSS THE NW GULF.
MOSTLY LIGHT TO GENTLE E-SE WINDS WITH SEAS OF 2-3 FT WILL PREVAIL
ACROSS MUCH OF THE REGION THROUGH SUN MORNING. WINDS WILL
SLIGHTLY INCREASE AND BECOME E-NE MON AND TUE WITH SEAS TO AROUND
4 FT. A COLD FRONT WILL APPROACH THE TEXAS COAST TUE NIGHT.

55W AND 65W...

DECREASE LATER TODAY AS THE WAVE MOVES FURTHER WEST. A SECOND
TROPICAL WAVE WILL MOVE ACROSS THE TROPICAL N ATLC LATER TODAY
AND ACROSS THE EASTERN CARIBBEAN SAT. SWELLS ASSOCIATED WITH A
LOW PRES SYSTEM IN THE CENTRAL ATLC HAVE MOVED INTO THE NE PORTION
OF THE TROPICAL N ATLC. E SWELL GENERATED BY STRONG WINDS N OF A
LOW PRES SYSTEM IN THE CENTRAL ATLC...WITH MEDIUM POTENTIAL TO
DEVELOP INTO A TROPICAL CYCLONE... ARE EXPECTED TO REACH THE

STALL AND WEAKEN TO A TROUGH LATER TODAY FROM 31N70W TO THE
CENTRAL BAHAMAS. THE WEAK TROUGH WILL LINGER ACROSS THE REGION
THROUGH SUN AND DRIFT EASTWARD. THIS WILL INDUCE AN EXTENDED
PERIOD OF LIGHT WINDS ACROSS THE AREA FRI THROUGH SUN ALLOWING
SEAS TO SUBSIDE TO 2 FT OR LESS. HIGH PRES BUILDING SOUTHWARD
ALONG THE EASTERN SEABOARD WILL TIGHTEN THE PRES GRADIENT...AND
INCREASE NORTHERLY WINDS IN THE NW PORTION OF THE AREA SUN AND
MON.
