Southeast Gulf of Mexico

.SYNOPSIS...Strong thunderstorms are expected to continue across
W Gulf of Mexico through Fri and will be capable of producing
locally near-gale force winds and seas to 10 ft. Meanwhile, a
strong ridge stretching from eastern seaboard to the NE Gulf
will continue to dominate the Gulf waters through the remainder
of the week. The pressure gradient between the ridge and
deepening low pressure across the Southern Plains and northern
Mexico will result in fresh to strong SE winds and high seas
across the Gulf region through Sat. Seas will peak 10 to 13 ft
today through Fri in the Straits of Florida and 12 ft in the N
central Gulf on Fri.

Within 200 nm east of the coast of Florida

.SYNOPSIS...A stationary front extends across the western Atlc
from 20N70W to the southeast Bahamas. This front will weaken and
dissipate through Fri as it sinks southward and approaches the 
Windward Passage and Hispaniola. Meanwhile, the pressure
gradient between high pressure off the eastern seaboard and the
frontal boundary will support an area of fresh to strong easterly
winds N of the front and W of 68W through late Fri. Seas will 
peak around 9 ft E of the Bahamas today. Large NE swell will enter
the NE waters early Sat and spread across the area waters through
Mon.
