Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A surface trough extending from near Miami, FL 
northeastward to 31N74W will be the focal point for scattered to
numerous showers and thunderstorms over the next couple of days,
along and east of the trough. A broad area of low pressure is 
expected to form along this trough tonight to the southwest of 
Bermuda, when the trough is forecast to extend from 30N69W to 
South Florida. Fresh to strong winds are likely near and to the
SE of the low as it shifts E along a frontal boundary to the S
of Bermuda on Fri. Fresh to locally strong N to NE winds and 
building seas are expected N of 27N and W of 74W Sun through Mon 
in the wake of a cold front. This cold front should reach from 
near 31N63W to the central Bahamas by late Mon night.
