Synopsis for the Gulf of Mexico

.SYNOPSIS...A 1014 mb low pres centered off the coast of Texas
near 28N94W 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.
