Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A trough extends from Hispaniola to 26N63W. The pressure gradient between the trough and strong high pressure north of the region is supporting strong to near gale- force easterly winds and rough to very rough seas across the waters northwest of the trough. The trough will shift westward today, as building high pressure north of the area follows a cold front moving across the western Atlantic before becoming stationary and weakening along 22N by Wed. High pressure building to the north will support fresh to strong easterly winds and rough to very rough seas across the basin by mid week. Looking ahead, a trough will develop along the dissipating front, north of the Leeward Islands by Thu, then move west across Puerto Rico and Hispaniola through Fri.
