.SYNOPSIS...Atlantic high pressure is centered along the middle
Atlantic coast of the U.S. and will shift E-NE and strengthen

southeastern U.S. Fri night. Strong southerly winds will expand

increasing to gale-force across the northern waters Fri evening
through Sun. The front will exit NE Florida Sat afternoon, reach
from near 31N72W to central Cuba on Sun morning, from 31N64W to
the Windward Passage by Mon morning, then weaken considerably as
it moves SE across the NE Caribbean and adjacent Atlantic waters
through Tue. Strong to near gale-force NE winds and large NE to N
swell will follow the front Sun through Mon.
