SYNOPSIS FOR KEYS COASTAL WATERS FROM OCEAN REEF TO DRY TORTUGAS
438 AM EST SAT FEB 28 2026
SYNOPSIS
AN ATLANTIC RIDGE ACROSS SOUTH FLORIDA WILL PULL FURTHER EAST
WHILE A FRONTAL BOUNDARY STALLS ACROSS NORTH CENTRAL FLORIDA. THE
COMBINATION OF THESE FEATURES WILL RESULT IN LIGHT BREEZES LIKELY
BECOMING VARIABLE THIS AFTERNOON. THEREAFTER, A BROAD HIGH
PRESSURE SYSTEM IS FORECAST TO MIGRATE INTO THE EASTERN UNITED
STATES, THEN OUT INTO THE ATLANTIC. THIS IS EXPECTED TO SUPPORT
FRESHENING BREEZES, ESPECIALLY ACROSS THE STRAITS OF FLORIDA.
A MIX OF CAUTIONS AND ADVISORIES IS BECOMING INCREASINGLY LIKELY
FOR THE BULK OF THE WORK WEEK.
