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 stationary front extends west from Tampa Bay Florida to 
28N93W. Fresh to locally strong easterly flow continues north of 
the front. The stationary front will move north tonight as ahead 
of a cold front reaching the Texas coast around sunrise on Sun 
preceded by a pre-frontal squall line. The cold front will reach 
from the Mississippi Delta to the Bay of Campeche on Sun night, 
from the Florida Big Bend to the Yucatan Peninsula on Mon night, 
then slow somewhat on Tue passing through the Straits of Florida 
late Wed.   

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

Atlantic high pressure will maintain fresh to locally strong 
trades across the south-central Caribbean and along the southern 
coast of Hispaniola through early Sun. Strong nocturnal trades 
are then expected to resume on Sun night along the north coast 
of the South America. A weakening cold front will pass southeast 
through the Yucatan Basin on Tue night, and wash out across the 
northwest Caribbean during the middle of next week.   

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

Remnants of a stationary front extending southwest from 29N65W 
to central Florida will lift north on Sun with near gale force 
southeast flow developing across the forecast waters north of 
the Bahamas on Mon in association with a surface low shifting 
east across the southeast United States. The surface low will 
move northeast along the Georgia and South Carolina coasts on 
Tue, and drag a a couple of weak cold fronts across the 
northwest waters during the middle of next week.
