...GULF OF MEXICO... 

High pressure prevails over the forecast waters. Latest 
satellite derived winds and seas along with ship, buoy, and CMAN 
data depict light to gentle winds over the northeast Gulf, and 
gentle to moderate winds elsewhere. Seas are in the 1-2 ft range 
over the northeast Gulf, 4-5 ft over the northwest Gulf, and 2-4
ft elsewhere. A thermal trough will develop late each afternoon 
over the Yucatan Peninsula. The trough will shift westward across
the southwestern Gulf waters during the overnight hours and 
dissipate over this area each morning. High pressure will prevail
elsewhere over the Gulf waters through Wed night.
  
...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN

Latest satellite derived winds and seas along with ship, buoy,

remainder of the Caribbean as well as the tropical north 
Atlantic forecast zones. Seas are in the 5-8 ft range over the 
central Caribbean, 3-5 ft over the eastern Caribbean, 5-7 ft over
the western Caribbean, and 5-6 ft over the tropical north 
Atlantic waters. Winds and seas across the forecast waters will
continue to decrease this weekend. High pressure will build back
north of the area early next week, once again tightening the 
pressure gradient and increasing winds and seas by midweek. 

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

A weakening cold front extends from near Bermuda to the northern
Bahamas. Latest satellite derived winds and seas along with 
ship, buoy, and CMAN data depict gentle to moderate winds over 
the far southern waters while light to gentle winds prevail 
elsewhere. Seas are in the 2-4 ft range outside the Bahamas and 
1-3 ft west of the Bahamas. The front will dissipate by Sunday. 
High pressure will then build back across the area the remainder
of the weekend into early next week then prevail through the
