SYNOPSIS FOR THE GULF OF AMERICA
1021 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.
