Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front has pushed southeast of the basin
extending from the Straits of Florida northeast across the SW N
Atlantic. A trough in the west-central Gulf to eastern Bay of
Campeche combined with high pres north of the area supports
fresh to strong winds northeast of the trough. Low pres will
move from NE Mexico to offshore Texas by early this evening with
a warm front extending northeast and a developing cold front
trailing to the southwest. The low will shift east-southeast
toward SW Florida through mid-week while the cold front slowly
moves eastward, stalling and weakening by mid-week. A stronger
cold front may move off the Texas coast into the far northwest
Gulf Thu night followed by near-gale or gale force winds and
rough to very rough seas across the basin through Fri night,
with strong gales possible off Veracruz.
