SYNOPSIS FOR KEYS COASTAL WATERS FROM OCEAN REEF TO DRY TORTUGAS
1031 AM EST SUN NOV 23 2025
SYNOPSIS
LIGHT, PREDOMINANTLY NORTHEASTERLY BREEZES WILL
LINGER THIS AFTERNOON INTO TOMORROW DUE TO WEAK RIDGING ACROSS
FLORIDA. A CONTINENTAL HIGH WILL PUSH IN TO THE EASTERN UNITED
STATES EARLY THIS WEEK, RESULTING IN FRESHENING NORTHEAST TO
EASTERLY BREEZES. THIS HIGH WILL PROGRESS EASTWARD INTO THE
ATLANTIC, AND AFTER MID WEEK, BREEZES SHOULD COLLAPSE AS THE
PRESSURE FIELD BECOMES NEBULOUS. PROBABILITY IS INCREASING THAT A
COLD FRONT WILL PUSH SOUTHWARD THROUGH KEYS WATERS VERY LATE IN
THE FORECAST, RESULTING IN WHAT APPEARS TO BE THE START OF A
PROLONGED PERIOD OF FRESH NORTHEAST TO EASTERLY BREEZES.
