Synopsis for the Gulf of Mexico

.SYNOPSIS...A 1010 mb low pres has developed over the central
Gulf near 26N89W, with a stationary front extending ESE to the
Florida Keys. Strong to near gale force E winds, with gusts to
gale force, are observed in the NE semicircle of the low. These
strong to gale force winds will continue over the NE and
north-central Gulf through tonight as the low moves N. The low
will move inland over the U.S. north-central Gulf Coast on Thu.
Once the low moves inland, marine conditions will improve Thu
afternoon and evening. For the weekend, a cold front is forecast
to enter the western Gulf which will cause winds and seas to
increase.
