Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...The pressure gradient between a 1016 mb low centered near 26N64W with associated trough and high pressure centered over the central Atlantic is supporting fresh to locally strong northeast winds and moderate to rough seas north and northeast of the low. These conditions will gradually shift westward through mid- week as the low and trough drift westward. Winds and seas will start to decrease mid- week as the low and trough start to weaken. A stationary front along and just offshore the southeastern U.S. coast will gradually lift back northwest as warm front through mid-week, then may slowly push offshore again at the end of the week.
