Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Fresh winds S of 24N, locally strong offshore
Hispaniola, will diminish into Thu as the pressure gradient
relaxes due to the Bermuda high to the north shifting to the
east. This will allow a weak cold front to move off the SE U.S
coast Thu night, then stall over the far NW basin Fri into the
weekend. An area of low pressure could develop along this
boundary offshore the SE U.S, or over FL or adjacent waters of
the Gulf. Conditions are marginally conducive for development
and a tropical or subtropical depression may form in the region
this weekend or early next week while the system moves little.
Regardless of development, heavy rain and thunderstorms are
possible over Florida and nearby waters. There is a medium chance
of tropical formation through the next 7 days.
