Synopsis for the SW N Atlantic including the Bahamas
422 PM EDT Mon Sep 14 2026
.SYNOPSIS...A broad subtropical ridge dominates much of the
basin, forcing fresh easterly winds off Hispaniola and in the
Windward Passage. 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
locally strong and causing 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.
