Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.

Synopsis for the Gulf of Mexico

.SYNOPSIS...A 1014 mb low pres centered off the coast of Texas
near 28N96W will move eastward across the Gulf of Mexico through
Tue, with a cold front extending SSW and a warm front extending
E from the low. The gradient between the low and strong high
pressure over the SE United States will cause winds to gale
force over the NE Gulf of Mexico on Tue afternoon. The low will
shift east-southeast toward South Florida by late Tue night
while the cold front slowly moves eastward, stalling and
weakening by mid- week. Fresh to strong N winds are expected
behind the front Tue and Tue evening. Scattered showers and
thunderstorms are expected with the low and front. Looking
ahead, a stronger cold front is expected to move off the Texas
coast Thu evening followed by near-gale to gale force winds and
rough to very rough seas across the basin through Fri night,
with strong gales possible off Veracruz.
