SYNOPSIS FOR THE GULF OF AMERICA
921 PM EDT TUE SEP 8 2026
SYNOPSIS
WEAK HIGH PRESSURE WILL PERSIST ACROSS THE GULF
THROUGH THE WEEKEND, PRODUCING A WEAK PRESSURE GRADIENT. THIS
WILL SUPPORT MOSTLY LIGHT TO GENTLE WINDS AND SLIGHT SEAS OVER
MUCH OF THE WATERS. WINDS WILL PULSE TO FRESH WITH MODERATE SEAS
OFF THE WESTERN YUCATAN PENINSULA DURING THE EVENINGS DUE TO A
DIURNAL SURFACE TROUGH MOVING WESTWARD FROM THE PENINSULA EACH
NIGHT.
