SYNOPSIS FOR THE GULF OF AMERICA
423 AM EDT WED AUG 19 2026
SYNOPSIS
HIGH PRESSURE WILL PREVAIL ACROSS THE GULF WATERS
THROUGH THE FORECAST PERIOD. A WEAK PRESSURE PATTERN WILL
SUPPORT MOSTLY GENTLE TO MODERATE WINDS AND SLIGHT TO LOCALLY
MODERATE SEAS 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.
