Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A stationary front extends from 31N70W southwestward
to a weak 1014 mb low pres near 26N74W, and then extends to SE 
Cuba. The southern portion of the front should dissipate by Thu,
while the northern portion should remain nearly stationary until
dissipating by Fri. A surface trough is likely to form by Fri
night and persist through Sun east of the Bahamas. The trough
should strengthen trades between Bermuda and the Bahamas on Sat 
and Sun before weakening on Mon. A weak cold front should move 
off the coast of NE Florida Sat night, but dissipate north of
the Bahamas by Mon. Finally, moderate N swell is anticipated to 
impact the N waters east of 60W beginning on Sat.
