Southeast Gulf of America

.SYNOPSIS...Weak surface 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. 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.

or less. Scattered showers and isolated tstms.
