Synopsis for the SW N Atlantic including the Bahamas
1028 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 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 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.
