Detailed Forecast

IMPORTANT NOTICE TO MARINERS...MARINE FORECASTS ARE ISSUED AT LEAST FOUR TIMES A DAY. BOATERS ON EXTENDED TRIPS SHOULD ROUTINELY MONITOR SUBSEQUENT FORECAST ISSUANCES AND UPDATES FOR THE LATEST MARINE WEATHER INFORMATION. THE WAVE HEIGHTS ARE FORECAST AS SIGNIFICANT WAVE HEIGHT WHICH IS THE AVERAGE OF THE HIGHEST ONE-THIRD OF THE WAVES. THE HIGHEST WAVES MAY RARELY BE TWICE THE SIGNIFICANT WAVE HEIGHT. THE WINDS AND SEAS NEAR THUNDERSTORMS MAY BE HIGHER THAN FORECAST.

  • SynopsisSTRONG HIGH PRESSURE RIDGING DOWN THE EASTERN SEABOARD WILL KEEP THE LOCAL GRADIENT TIGHT INTO THIS EVENING ACROSS THE EASTERN GULF OF MEXICO. ADVISORY LEVEL WINDS AND SEAS OVER THE OFFSHORE WATERS EARLY THIS MORNING HAVE ENDED BUT MAY ONCE AGAIN BRIEFLY OCCUR THIS EVENING BEFORE THE GRADIENT BEGINS TO RELAX EARLY SUNDAY MORNING. WINDS AND SEAS SUNDAY AND MONDAY ARE EXPECTED TO REMAIN BELOW 15 KNOTS...WITH WINDS LOCALLY TURNING ONSHORE EACH AFTERNOON DUE TO SEA BREEZE DEVELOPMENT. HIGH PRESSURE WILL SHIFT EASTWARD INTO THE ATLANTIC TUESDAY INTO WEDNESDAY ALLOWING WINDS OVER THE EASTERN GULF TO SHIFT SOUTHEAST AND EVENTUALLY SOUTH WITH TIME. AS WINDS BECOME MORE SOUTHERLY LATER TUESDAY INTO WEDNESDAY. THE RISK LOOKS TO INCREASE FOR THE DEVELOPMENT OF SEA FOG OVER THE NEAR SHORE WATERS AND BAYS.
