SYNOPSIS FOR ALTAMAHA SOUND GA TO FLAGLER BEACH FL OUT TO 60 NM-
231 AM EDT WED SEP 3 2025
SYNOPSIS
LOW PRESSURE POSITIONED EAST OF THE GULF STREAM WATERS ADJACENT TO
THE SOUTHEASTERN SEABOARD WILL WEAKEN AS IT MOVES FURTHER OFFSHORE
TODAY AND TONIGHT. MEANWHILE, HIGH PRESSURE ALONG THE U.S. EASTERN
SEABOARD TODAY WILL WEAKEN AS IT PUSHES OFFSHORE TONIGHT. BREEZY
NORTHEASTERLY WINDS WILL CONTINUE TODAY AS SEAS CONTINUE TO
GRADUALLY SUBSIDE, WITH SCATTERED SHOWERS POSSIBLE FOR THE WATERS
SOUTH OF ST. AUGUSTINE. MEANWHILE, A FRONTAL BOUNDARY CURRENTLY
STALLED NEAR THE FLORIDA KEYS WILL LIFT SLOWLY NORTHWARD THROUGH THE
FLORIDA PENINSULA ON THURSDAY AND FRIDAY, WITH ANOTHER WEAK LOW
PRESSURE CENTER DEVELOPING ALONG THIS FRONT EAST OF CAPE CANAVERAL.
THIS FEATURE WILL LIKELY MAINTAIN GENERALLY LIGHT ONSHORE WINDS
ACROSS OUR LOCAL WATERS THROUGH THE WEEKEND. A FRONTAL BOUNDARY WILL
THEN APPROACH OUR REGION FROM THE NORTHWEST ON SUNDAY, WITH THIS
FRONT THEN STALLING ACROSS OUR LOCAL WATERS EARLY NEXT WEEK,
BRINGING INCREASING CHANCES FOR SHOWERS AND THUNDERSTORMS.
