Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
424 AM EST Thu Feb 12 2026
.SYNOPSIS...A nebulous pressure pattern across the Florida Keys
coastal waters will support light and at times variables winds
through Friday night. High pressure diving off the Mid-Atlantic
coastline will interact with a developing area of low pressure
near the ARK- LA- TEX region by Saturday and Saturday night,
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.
