Southeast Gulf of America

.SYNOPSIS...Weak ridging across the southeastern U.S. will
maintain generally gentle to moderate winds across the basin
through mid week. A vigorous upper-level low and associated
surface low or trough over the central Gulf will contribute to
scattered showers and thunderstorms over the eastern Gulf
through the midweek, with the Straits of Florida the most active
area. Looking ahead, a cold front may sink into the northern
Gulf Thu night through Fri, leading to a modest increase in
winds across the basin.

Within 200 nm east of the coast of Florida

.SYNOPSIS...A very weak pressure gradient across the western
Atlantic will promote variable gentle to moderate winds across
forecast waters through early Thu. A vigorous upper-level low 
over the Gulf of America and Florida, and abundant tropical 
moisture across the Atlantic will force scattered showers and 
thunderstorms across the waters west of 70W through Wed. Low
pressure will deepen offshore of the middle Atlantic coast of
the U.S. late Wed through Fri, allowing a cold front to move
into the far NW waters and N Florida Thu through Fri. The front
will be  accompanied by increasing winds and the potential for
large N-NE  swell.
