Synopsis for the Gulf of Mexico

.SYNOPSIS...A strong cold front, that passes through Florida
about 30 nm to the NNW of Lake Okeechobee, into the Yucatan
Peninsula, will move southeast of the area later today.
Northerly gale-force winds, and large seas behind the front in
the SW Gulf, will persist through the early evening. The wind
speeds and the sea heights will diminish in the central and
western sections of the Gulf, on Thursday and Thursday night.
Strong NE to E winds will continue in the Straits of Florida,
after the frontal passage, from Thursday through Friday night.
A low pressure center is expected to develop in the eastern
Gulf on Friday night, and move across northern Florida during 
the weekend. Gale-force winds are possible in the eastern Gulf 
with the low pressure center.
