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 extending from near Tampa Bay, FL to the
north-central Gulf near 27N90W to the western Bay of Campeche is
beginning to lift N early this morning. Southerly moderate winds
are ahead of the front in the SE Gulf along with seas in the 3 to
4 ft range. Light to gentle variable wind is in the remainder
basin with 2 to 3 ft seas. A second push of cold air and a 
developing low pressure center along the frontal boundary over 
the NE Gulf will allow the transition to a cold front Monday 
evening. The low will move NE across Florida toward the western 
Atlantic Ocean late on Mon, thus dragging the cold front across 
the SE Gulf and South Florida by Wed. High pressure building N
of the front will lead to the development of fresh to strong N to
NE winds west of the front Tue morning through early Wed. The 
front will dissipate across the Straits of Florida Thu and return
flow will establish basin-wide on Fri.

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

Moderate to fresh trades are across the Caribbean except in the
lee of Cuba and in the SW basin W of 80W where winds are light to
gentle. Seas are in the range of 2 to 3 ft in the northern half
of the basin while 4 to 5 ft seas dominate the waters in the Gulf
of Honduras, the south-central and SE Caribbean. Fresh to 
strong winds in the south-central Caribbean near the coast of 
Colombia will prevail through Wed morning, then will resume again
Fri night. Fresh to locally strong winds are forecast in the 
Gulf of Honduras tonight and Tue, then will resume Fri night. 
Moderate to fresh trades will continue through Fri except for 
the NW basin where gentle to moderate trades will dominate. 

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

A cold front extends from 30N64W to 27N73W where it stalls to 
Cape Canaveral, Florida. Seas increase NE of the Bahamas from 3
to 9 ft in NW swell. The stationary portion of the front is 
forecast to lift back N as a warm front this morning and connect 
with a low pres that will move from the NE Gulf of Mexico to 
South Carolina adjacent waters Mon night. The low will move E-NE 
on Tue dragging a cold front across Florida through late Wed. The
front will then dissipate in the Straits of Florida on Thu. 
Fresh to strong SW winds and building seas will precede the 
front. Return flow will establish across the forecast waters Fri 
night.
