Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A strong extratropical cyclone (former Tammy)
associated with a stationary front is located near 31N59W or a
few hundred miles east-southeast of Bermuda. There is a
possibility 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 is now in effect for portions of
the area SE of Bermuda. Gales will continue into Fri. The
gradient between former Tammy and high pressure NW 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 area
through the week.
