Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...The pressure gradient between a low centered near
26N64.5W with associated trough and high pressure centered over
the central Atlantic is supporting fresh to locally strong
northeast winds and moderate to rough seas north and northeast
of the low. These conditions will gradually shift westward
through mid-week as the low and trough drift westward. Winds and
seas will start to decrease Wed night as the low and trough start
to weaken. A stationary front along and just offshore the
southeastern U.S. coast will gradually lift back northwest as
warm front through mid-week, then may slowly push offshore again
at the end of the week and into the upcoming weekend.
