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.
