.SYNOPSIS...High pressure prevails across the basin. Moderate to
fresh northerly flow will gradually shift E to SE today as high

winds into the NW and SW Gulf on Thu. Seas of 10-12 ft will 
prevail in the vicinity of the front. High pressure will build 
again in the wake of the front across the basin through the 
weekend.
