Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1030 AM EST Sat Feb 14 2026
.SYNOPSIS...High pressure centered near the coastal Carolinas
will promote veering light to gentle breezes today. The high will
dive off the Mid- Atlantic coastline and interact with a
developing area of low pressure north of the Gulf Coast tonight
into 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. Breezes will quickly slacken
and veer to the northeast on Tuesday, as the next high pressure
slides into the eastern Gulf Basin.
