SYNOPSIS FOR THE GULF OF AMERICA
411 AM EDT TUE AUG 18 2026
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.
