will continue over the NE Gulf into this evening. Trailing fresh
to strong winds and rough seas in the eastern Gulf will gradually
diminish on Mon. Conditions are forecast to improve on Mon as high

emerge from the coast of Texas Wed night and extend from the
Florida Big Bend to Tampico, Mexico Thu night.

A cold front extends from western Cuba to western Honduras, with
scattered moderate and isolated strong convection within 90 nm

central and eastern Caribbean, with gentle to moderate winds
elsewhere. Seas are in the 4-6 ft range over the south central
Caribbean, 3-4 ft over the north central and eastern Caribbean,
and 1-3 ft elsewhere.

For the forecast, moderate to fresh trade winds in the eastern
and central Caribbean will continue through Thu night. Otherwise,
a cold front extending from Tampa Bay to Cancun is forecast to
enter the NW Caribbean later this morning, followed by fresh to
strong NW winds and building seas. The front will extend from
