Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Hurricane Nigel is near 30.5N 54.3W at 11 AM EDT, and is moving north-northwest at 14 kt. Maximum sustained winds are 80 kt with gusts to 100 kt, and the minimum central pressure is 975 mb. Nigel will move N of area to near 32.3N 54.7W this evening. Strong winds and rough seas associated with Nigel will continue to affect the forecast waters through late Wed or Wed evening. A stationary front extending from near 31N71W to South Florida will change little through Thu. The boundary should begin to slowly lift northward on Fri as low pressure develops along it to the east of northern Florida. Winds and seas will likely increase in that area by the end of the week as a tight pressure gradient develops between the developing low pressure off the Carolinas and high pressure inland over the U.S. Gale- force northerly winds are expected off the southeastern U.S. coast Fri through Sat.
