Marine Weather Discussion
NWS National Hurricane Center Miami FL
315 AM EDT Thu Sep 21 2017

Marine Weather Discussion for the Gulf of Mexico, Caribbean Sea,
and Tropical North Atlantic from 07N to 19N between 55W and 64W
and the Southwest North Atlantic including the Bahamas.

...GULF OF MEXICO...

A thermal trough will develop each evening over the NW Yucatan
Peninsula, move W-NW across the SW Gulf during the overnight
hours and dissipate over the SW Gulf waters by late each
morning.  Expect the trough to be accompanied by a moderate to
locally fresh NE-E-SE wind shift and brief seas to 4 ft. A
surface high will meander over the N-Central waters through Thu
night, then shift N and inland Louisiana on Fri with light to
locally moderate anticyclonic flow and 1 to 3 ft seas through
Mon.

...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...

Marine interests should monitor the latest NHC bulletins
concerning major hurricane Maria currently moving to the north of
Hispaniola, with seas in excess of 35 ft. Strong or greater
southerly flow expected across the Caribbean waters N of 15N E of
73W today. Expect wind/sea conditions across the NE passages to
diminish to 20 kt or less, and seas to subside to less than 8 ft
on Fri morning. Fresh N winds and seas to about 8 ft expected in
the Windward Passage late Thu night into Fri morning. Elsewhere,
moderate to locally fresh trades will return by Sun evening.

...SW N ATLANTIC INCLUDING THE BAHAMAS...

Major Hurricane Maria is off the north coast of the Dominican
Republic, moving NW. Maria will begin to move more NNW this
morning and later N in response to a weakness in the subtropical
ridge. This track keeps the center of Maria E of the central and
northern Bahamas. Given that forecast track and intensity
accuracy decreases further into the future, marine interests
throughout the region should continue monitoring the latest
bulletins issued by the National Hurricane Center on Hurricane
Maria.
