Synopsis for the Gulf of Mexico

.SYNOPSIS...A cold front extends from near Fort Myers, Florida
to 25N90W, then stationary to the central Bay of Campeche. The
front will move southward across the SE Gulf into the Straits of
Florida overnight, except lift northward over the western Gulf
ahead of low pressure moving through northeast Mexico. The whole
front will lift northward Tue as a warm front while the low
pressure moves into the north- central Gulf. A trailing cold
front over the western Gulf will dissipate through mid week.
Looking ahead, 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, with strong gales possible off
Veracruz.
