Synopsis for the SW N Atlantic including the Bahamas
430 AM EDT Wed Oct 21 2026
.SYNOPSIS...Moderate to fresh N to NE winds and large NE swell
persist west of a stationary front that extends from 31N66W to
the southeastern Bahamas and to central Cuba. Winds will diminish
into Wed as the frontal boundary weakens. Lingering swell will
slowly subside through Fri. A tightening pressure gradient will
develop beginning late Fri as high pressure builds southward over
the western Atlantic and low pressure develops near, or NE of the
Bahamas along a remnant frontal trough. This setup is expected to
induce widespread near to gale-force NE winds over the waters
roughly NW of a line from near 31N61W to the northern Bahamas.
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.
