SYNOPSIS
A WEAK HIGH PRESSURE PATTERN WILL SUPPORT MOSTLY
GENTLE TO MODERATE WINDS ACROSS MUCH OF THE BASIN. A DIURNALLY
INDUCED SURFACE TROUGH WILL GENERATE FRESH TO LOCALLY STRONG
WINDS NORTH AND WEST OF THE YUCATAN PENINSULA EARLY EACH EVENING.
THESE WINDS WILL SPREAD WESTWARD AWAY FROM THE YUCATAN AT NIGHT
AS THE TROUGH MIGRATES INTO THE SW GULF. SLIGHT TO MODERATE SEAS
ARE EXPECTED THROUGH THE FORECAST PERIOD.
