SYNOPSIS FOR THE GULF OF AMERICA
310 PM 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 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.
