Southeast Gulf of America



.SYNOPSIS...Weak surface ridging across the southeastern U.S.

will maintain generally gentle to moderate winds across the

basin through midweek. A vigorous upper-level low and associated

surface trough over the southern Gulf will contribute to

scattered showers and thunderstorms over the eastern Gulf

through  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.
