Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
430 PM EST Fri Feb 13 2026
.SYNOPSIS...A nebulous pressure pattern across the coastal waters
of the Florida Keys will support light and at times variable
breezes through this evening and early overnight. Thereafter, high
pressure diving off the Mid- Atlantic coastline will interact
with a developing area of low pressure north of the Gulf Coast
Sunday, supporting freshening east to southeast breezes. The low
pressure system will nudge a frontal boundary through the Keys
Monday evening. A potent surge of northerly breezes is not
expected in the wake of this front. Behind this front, breezes
will slacken appreciably as the next high pressure slides into the
eastern Gulf Basin.
