SYNOPSIS FOR THE GULF OF AMERICA
436 PM EDT WED AUG 19 2026
SYNOPSIS
RELATIVELY WEAK HIGH PRESSURE CENTERED OVER THE
CENTRAL GULF WILL PREVAIL OVER THE BASIN 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 IN THE
EARLY EVENINGS. THESE WINDS WILL SPREAD WESTWARD AWAY FROM THE
PENINSULA AT NIGHT AS THE TROUGH MIGRATES INTO THE SW GULF.
