Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1028 PM EDT Sun Mar 29 2026
SYNOPSIS
A frontal boundary is currently draped from north of
the Bahamas through South Florida and across the Gulf towards
Mexico. This front will continue to slowly drift southward this
tonight resulting in freshening northeast to east breezes. In the
wake of the front, strong Canadian high pressure will traverse
across the Mid- Atlantic tonight. This high will continue to move
eastward and setup shop across the central North Atlantic for much
of the week. This will promote mainly fresh to strong easterly
breezes through at mid-late week.
