Synopsis for the Gulf of Mexico

.SYNOPSIS...The portion of a cold front that extends from South
Florida to just NE of Veracruz, Mexico, is beginning to stall
early this morning, while the portion that extends south from
offshore Veracruz into the Bay of Campeche continues to move E.
Low pressure will form well E of Tampico, Mexico today, then
track NE into Tue. The portion of the front to the east of the
low will retreat north as a warm front, while the cold front
will continue to the south of the low. Gales offshore Veracruz
early this morning will propagate NE through the day, to the N
and W of the center of the low, and into the north-central Gulf
of Mexico. The low and cold front will move east and through the
basin by later on Tue, with strong winds and high seas impacting
most of the basin, before conditions improve Wed, as weak high
pressure builds into the area.
