Southeast Gulf of Mexico .SYNOPSIS...A tight pressure gradient between the E Pacific monsoonal flow and surface ridging across the northern Gulf of Mexico is supporting fresh to strong E winds and rough seas in the Bay of Campeche and moderate to fresh E winds elsewhere. Winds over the SW basin are forecast to reach near gale-force later today as a broad area of low pressure is expected to form over SE Mexico, thus increasing the pressure gradient further. Environmental conditions appear conducive for gradual development after this system moves over the Bay of Campeche tonight, and a tropical depression could form over the SW Gulf of Mexico this weekend while it moves slowly west-northwestward or northwestward. Winds E of 90W are forecast to diminish to gentle to moderate speeds Sat night and to light to gentle speeds on Sun. Conditions are forecast to improve W of 90W Sun night into Mon. .THIS AFTERNOON...E winds 15 to 20 kt. Seas 4 to 6 ft. .TONIGHT...E winds 10 to 15 kt. Seas 3 to 5 ft.

Within 200 nm east of the coast of Florida .SYNOPSIS...A small area of showers and thunderstorms persists with a 1014 mb low pressure system located near 30N79W or around 130 nm E-SE of Jacksonville, Florida. Environmental conditions remain marginally conducive for some additional development, and this system could become a short-lived tropical depression as the low moves W-NW at 10 to 15 kt. The system is expected to reach the coast of NE Florida or Georgia by tonight. Regardless of development, fresh to near gale force NE to E winds and rough seas to 10 ft will prevail across the waters N of 30N and W of 77W through today. Afterward, high pressure will build in the wake of the low, supporting gentle to moderate winds through Tue night.
