Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front will move through the area, including the Bahamas today, reaching Bermuda by the evening, then slowing and gradually stalling into the weekend over the SE waters and Hispaniola.

A secondary surge of high pressure and reinforcing cold front will likely sweep across northern areas Fri through Sat nights, possibly bringing another round of strong W to NW winds.
