Synopsis for the SW N Atlantic including the Bahamas
435 AM EDT Tue Oct 20 2026
.SYNOPSIS...Moderate to fresh N to NE winds and large NE swell
persist west of a stationary reaching from 31N67W to the central
Bahamas to northwest 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.
