SYNOPSIS FOR KEYS COASTAL WATERS FROM OCEAN REEF TO DRY TORTUGAS
1021 AM EDT THU MAY 1 2025
SYNOPSIS
A BROAD HIGH PRESSURE LOCATED WEST OF BERMUDA WILL CONTINUE TO
INFLUENCE OUR WINDS THROUGH THE NEXT COUPLE OF DAYS. AS A RESULT,
BREEZES WILL OSCILLATE BETWEEN MODERATE TO FRESH ON A WEAK DIURNAL
TREND, WITH STRONGER BREEZES IN THE EVENING HOURS. AN APPROACHING
LOW PRESSURE SYSTEM MOVING THROUGH THE GREAT LAKES REGION THIS
WEEKEND WILL WEAKEN THE PRESSURE GRADIENT ACROSS OUR AREA AND LEAD
TO A BRIEF LULL IN WINDS. LASTLY, OCCASIONAL PUSHES OF MOISTURE
THROUGHOUT THE FORECAST PERIOD WILL ALLOW FOR SOME ISOLATED TO
SCATTERED SHOWER ACTIVITY.
