Synopsis for the SW N Atlantic including the Bahamas
440 AM EDT Sun Sep 13 2026
.SYNOPSIS...A broad subtropical ridge will persist over the basin
through Mon night, bringing mainly tranquil marine conditions.
However, trades north of Hispaniola into the Windward Passage will
be fresh to locally strong into Mon. On Tue, strong high pressure
building southward through the eastern United States will bring a
cold front into the NW waters, increasing NE winds to fresh to
strong and causing seas to build to rough N of the Bahamas and W
of 70W Tue through Wed night. Conditions will improve late this week.
