Synopsis for the SW N Atlantic including the Bahamas
316 PM EDT Sat Apr 4 2026
.SYNOPSIS...High pressure is over just about the entire area.
The pressure gradient between the high pressure and relatively
lower pressure in the subtropics and tropics is producing fresh
to strong east winds south of about 26N. Rough seas are
present with these winds east of the Bahamas. Conditions will
improve Sun night into Mon as the high weakens and slides
eastward in response to an approaching cold front. This front will
slowly move off the southeastern U.S. and northeast Florida Sun
night reaching from near 31N76W to east-central Florida Mon
afternoon, from near 31N70W to South Florida Tue afternoon, from
near 31N63W to the Straits of Florida by Wed afternoon. then stall
into Thu night. Meanwhile, a trough that currently extends from
29N72W to the southeastern Bahamas is followed by increasing
showers and thunderstorms that reach to near 65W and from 21N to
25N. Similar activity is west of the trough to near 78W and from
21N to 25N. This trough will continue to drift west-northwestward
eventually merging with the frontal boundary late Tue. Low
pressure may then form along the frontal boundary and track
northeastward to north of 31N on Wed, while an expansive area of
strong high pressure builds southward up against the frontal
boundary and low pressure. The resulting tight pressure gradient
will lead to widespread strong to near gale-force northeast to
east winds behind the frontal boundary along with rough to very
rough seas beginning Tue. The potential exists for these winds
attaining gale-force speeds. Mariners are advised to keep up with
the latest forecast.
