DISCUSSION
A BROAD AREA OF HIGH PRESSURE CENTERED OVER THE EASTERN GULF WILL
BRING GENERALLY FAVORABLE MARINE CONDITIONS THROUGH SATURDAY NIGHT.
WINDS WILL BECOME SOUTHEASTERLY AT 5 TO 10 KNOTS TODAY BEFORE
INCREASING TO 10 TO 15 KNOTS TONIGHT. SEAS WILL REMAIN AT 3 FEET OR
LESS. THE PRESSURE GRADIENT WILL TIGHTEN ON SUNDAY AND SOUTHERLY
WINDS WILL INCREASE TO 15 TO 20 KNOTS BY THE AFTERNOON. SUNDAY NIGHT
INTO EARLY MONDAY WILL SEE A STRONG COLD FRONT PASS THROUGH THE
WATERS. AS THE FRONT PASSES, WINDS WILL QUICKLY SHIFT TO THE
NORTHWEST AND INCREASE TO 30 TO 35 KNOTS WITH HIGHER GUSTS. THESE
GALE CONDITIONS WILL PUSH SEAS OVER 12 FEET IN THE OPEN GULF WATERS
CREATING VERY HAZARDOUS BOATING CONDITIONS. THE GALE CONDITIONS WILL
LINGER INTO MONDAY NIGHT BEFORE GRADUALLY EASING ON TUESDAY AS
ANOTHER HIGH PRESSURE SYSTEM BECOMES MORE CENTERED OVER THE WATERS.
AS THE HIGH BECOMES CENTERED OVER THE WATERS ON WEDNESDAY, WINDS
WILL TURN MORE EASTERLY AND FALL TO 10 KNOTS OR LESS. SEAS WILL
ALSO DECREASE BACK TO 3 FEET OR LESS BY WEDNESDAY MORNING.
