SYNOPSIS FOR THE GULF OF AMERICA
1019 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 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.
