SYNOPSIS FOR KEYS COASTAL WATERS FROM OCEAN REEF TO DRY TORTUGAS
1021 PM EST MON NOV 24 2025
SYNOPSIS
A CONTINENTAL HIGH WILL GRADUALLY PUSH OFFSHORE OVER
THE NEXT COUPLE OF DAYS, RESULTING IN FRESHENING NORTHEAST TO
EAST BREEZES. WHILE THE CENTER OF THIS HIGH PROGRESSES EASTWARD
INTO THE WESTERN NORTH ATLANTIC, BREEZES WILL COLLAPSE BY MIDWEEK
AND THE PRESSURE FIELD WILL BECOME NEBULOUS. PROBABILITY IS
INCREASING THAT A COLD FRONT WILL PUSH SOUTHWARD THROUGH THE
FLORIDA KEYS COASTAL WATERS LATER THIS WEEK BEFORE STALLING,
RESULTING IN WHAT APPEARS TO BE THE START OF A PROLONGED PERIOD OF
FRESHENED NORTHEAST TO EASTERLY BREEZES THROUGH THE WEEKEND.
