Synopsis for the Gulf of Mexico

.SYNOPSIS...A ridge dominates the Gulf waters. The pressure
gradient between the ridge and lower pressure associated with a
cold front over SE Texas will support fresh SE to S winds across
the Gulf of Mexico through midday Wed. The cold front over Texas
will move over the western Gulf Wed afternoon. Fresh to strong
northerly winds and building seas will briefly follow this
front, which will stall over the west-central Gulf on Thu while
dissipating. A stronger cold front will enter the NW Gulf Thu
night, reach from the Florida Big Bend to Merida, Mexico Fri
evening, and exit the basin by Sat afternoon. Northerly gales
are possible near Tampico, Mexico early Fri afternoon, and
offshore Veracruz, Mexico Fri afternoon through early Sat. Gales
could also persist over the central Bay of Campeche into Sat
morning. Very rough seas are expected in the wake of the front,
especially over the SW Gulf. Winds and seas will gradually
subside Sun as a high pressure ridge moves over the basin.
