AMZ101-160745-
Synopsis for the SW N Atlantic including the Bahamas
339 PM EDT Tue Sep 15 2026
.SYNOPSIS...A cold front extending from just NW of Bermuda
southwestward to along 30N to northern Florida will shift slightly
southward through early Wed, then will become stationary from
Bermuda to the NW Bahamas by late Wed. A tight pressure gradient
between the building ridge over the eastern United States and the
front will result in fresh to locally strong NE winds and seas to
build to rough N of the Bahamas and W of 70W through early Thu.
Conditions will improve later Thu into Fri. During the middle to
later portion of the week, a trough of low pressure is forecast to
move west-northwestward into the NE portion of the waters,
bringing thunderstorms while also weakening the high and pressure
gradient.
