The front will come off the coast of Texas Wed morning, reach from
southern Alabama to Veracruz Wed night, from Cape Coral to the
Yucatan Peninsula Thu afternoon, and exit the basin Thu night into
Fri. The front will be followed by fresh to strong N winds and
rough seas, except for possible brief gales off Veracruz Thu
