SYNOPSIS FOR THE SW N ATLC INCLUDING THE BAHAMAS .SYNOPSIS...A trough extends from the central Florida coast near Cape Canaveral east-northeastward to a weak 1015 mb low at 29N73W.

Central Atlantic high pressure will build westward across the eastern part of the basin Fri through Mon, with the resultant pressure gradient allowing for fresh to strong E winds south of 23N. East winds will pulse to strong between the southeastern Bahamas and Hispaniola from the afternoons to overnight hours during the period.
