Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A strong extratropical cyclone, former Tammy, associated with an occluded front is located near 31N59W or a few hundred miles east-southeast of Bermuda. There is a possibility that this system could regain tropical or subtropical characteristics while it meanders over the northwestern Atlantic through early next week. High winds and hazardous seas are still present, and a Storm Warning remains in effect for portions of the area SE of Bermuda. Gales will continue into Fri. The gradient between former Tammy and high pressure N of the area will continue to support strong to near gale-fore NE winds and very rough seas well W of former Tammy across much of the forecast area through the week.
