Marine Weather HF Voice Broadcast for the Tropical N Atlantic
from 07N to 19N W of 55W, the N Atlantic from 19N to
31N W of 55W including the Bahamas, and the Caribbean Sea.

Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...A surface ridge extending southward from the eastern
Gulf of Mexico should sustain moderate to fresh N to NE winds
and moderate seas across the western Caribbean through early
Fri. Afterward, this high is going to build eastward into the
western Atlantic through early next week, causing these winds
and seas to also shift eastward into the central Caribbean. In
addition, winds at the south-central basin will pulse to strong
at night through early next week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extends from 31N47W to 20N70W. Fresh to
strong SW winds will persist ahead of the front mainly north of 
27N through tonight. Meanwhile, large long-period NW swell will 
sustain very rough to high seas across the waters north of 26N 
through Thu morning. A reinforcing cold front is expected to
bring strong to gale-force W to NW winds north of 27N and east
of 70W Thu afternoon through Sat. This will also prolong very 
rough to high seas in the central and eastern Atlantic through 
the weekend. In the long term, a third frontal system this 
weekend could bring yet another round of increasing winds and 
seas east of Florida and northeast of the Bahamas.
