Synopsis for the Gulf of Mexico

moderate to fresh SE to S return flow over the Gulf of Mexico
through Fri. The diurnal trough forming over the Yucatan will
promote strong E winds over E Bay of Campeche tonight.
Agricultural and seasonal fires over Mexico and Central America
result in smoke and haze over the the SW Gulf and the Bay
Campeche. Mariners may experience reduced visibility in these
waters. A cold front that is expected to enter the NW Gulf on
Fri night. Moderate to fresh N to NE winds will prevail behind
the front on Sat. By Sun morning, the dissipating front will
extend from SW Florida to near the Texas-Mexico border. Looking
