Synopsis for the SW N Atlantic including the Bahamas
301 PM EST Sun Mar 1 2026
.SYNOPSIS...A weak frontal boundary extends southwestward from
near 31N70W to the NW Bahamas and to the Florida Keys while a
trough ahead of it extends from 28N72W to the southeastern
Bahamas and to near eastern Cuba. Scattered to numerous showers
and thunderstorms are evident within 60 nm northwest of the
frontal boundary and within 30 nm southeast of the boundary N of
27N. To the east, numerous showers and thunderstorms are located
north of 26N and east of the frontal boundary and trough to a line
from 31N64W to 26N70W. A shortwave trough aloft shifting east-
southeastward stretches from near 31N75W to between South Florida
and Bahamas. It is providing favorable upper-level dynamics that
is sustaining the shower and thunderstorm activity for the time
being. The frontal boundary will weaken further as it slowly moves
southeastward reaching from near 31N67W to 28N70W and stationary
front to the Florida Keys tonight, and from near 31N62W to the
central Bahamas early on Mon as it becomes diffuse. Elsewhere,
high pressure over the central Atlantic continues to maintain
control over much of the western Atlantic while rough seas prevail
over the southeastern waters. Another cold front is expected to
enter the northern waters during the early part of the week and
gradually shift southeastward and weaken. Fresh to near gale-force
easterly winds and rough to very rough seas, peaking to around 13
ft, are forecast behind the front Mon through late Tue night
north of 27N. An expansive area of strong high pressure will build
across the north-central Atlantic by the middle of the upcoming
week resulting in moderate to fresh winds and rough seas over much
of the basin.
