Synopsis for the SW N Atlantic including the Bahamas
449 PM EDT Tue Oct 20 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 east-central Cuba. Winds will
diminish tonight into Wed as the frontal boundary begins to
weaken. Lingering swell will slowly subside through Fri. Looking
ahead, a tightening pressure gradient will develop beginning
late Fri as strengthening 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 31N51W to the central Bahamas and to
central Cuba, including the Straits of Florida. 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.
