SYNOPSIS FOR THE GULF OF AMERICA
528 AM EDT MON AUG 17 2026
SYNOPSIS
HIGH PRESSURE WILL PREVAIL ACROSS THE GULF WATERS
THROUGH THE WEEK. A WEAK PRESSURE GRADIENT WILL SUPPORT MOSTLY
GENTLE TO MODERATE WINDS ACROSS MUCH OF THE BASIN. A DIURNALLY
INDUCED SURFACE TROUGH WILL GENERATE FRESH TO OCCASIONALLY
STRONG WINDS N 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.
