Synopsis for the SW N Atlantic including the Bahamas
442 AM EDT Mon Sep 21 2026
.SYNOPSIS...A very weak pressure gradient across the western
Atlantic will promote variable gentle to moderate winds across
forecast waters through early Thu. A vigorous upper-level low
over the Gulf of America and Florida, and abundant tropical
moisture across the Atlantic will force scattered showers and
thunderstorms across the waters west of 70W through Wed. Low
pressure will deepen offshore of the middle Atlantic coast of
the U.S. late Wed through Fri, allowing a cold front to move
into the far NW waters and N Florida Thu through Fri. The front
will be accompanied by increasing winds and the potential for
large N-NE swell.
