Synopsis for the the SW N ATLC including the Bahamas

.SYNOPSIS...A stationary front extends from near 25N65W to 
23N71W, where it becomes a warm front to near 23N78W. The warm 
front will lift northward through Tue night while weakening. The
stationary portion will also weaken through Tue night. Easterly 
winds will increase across the entire region Wed and Thu as
strong high pressure builds over the western Atlantic. Seas will
build with these winds over most sections of the area. Winds
will diminish and seas will subside north of 22N Fri through Sat
night as the gradient associated with the high weakens in
response to a cold front that approaches from the northwest.
