NWS Marine Forecast

 
 AMZ101-210145-
 Synopsis for the SW N Atlantic including the Bahamas
 937 AM EDT Tue Oct 20 2026
 
 
 .SYNOPSIS...Moderate to fresh N to NE winds and large NE swell
 persist west of a cold front that extends from 31N67W to the
 southeastern Bahamas and to east-central Cuba. Winds will
 diminish tonight into Wed as the front dissipates, and lingering
 swell will subside through Thu. Looking ahead, a tightening
 pressure gradient developing late Fri is expected to induce
 widespread near to gale-force NE winds over the waters north of
 about 25N well into the weekend. Seas with these winds are
 expected to quickly build to rough to very rough. Mariners should
 monitor the latest marine forecasts, and have avoidance plans in
 place.
