Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
428 AM EST Sun Feb 15 2026
.SYNOPSIS...High pressure centered off the Carolina Outer Banks
interacting with low pressure on the north Gulf coast will
support moderate to fresh breezes across the Florida Keys early
today. Breezes will gradually slacken and veer as the high
escapes into the western North Atlantic and the low pressure
system nudges a frontal boundary towards the Keys. The front is
expected to pass through Monday evening without a potent surge of
northerly breezes in its wake. Breezes will continue to slacken
and veer to the northeast on Tuesday as the next high pressure
slides into the eastern Gulf Basin and keeps hold of our weather
pattern into the back half of the work week.
