Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
418 AM EST Fri Feb 13 2026
.SYNOPSIS...A nebulous pressure pattern across the Florida Keys
coastal waters will support light and at times variables winds
through tonight. High pressure diving off the Mid- Atlantic
coastline will interact with a developing area of low pressure
north of the Gulf Coast by, supporting freshening east to
southeast breezes. The low pressure system will drive a frontal
boundary through the Keys marine zones Sunday night into Monday,
with gentle winds clocking around to the northwest in its wake for
early next week.
