SYNOPSIS FOR THE GULF OF AMERICA
231 PM EDT THU MAY 21 2026
SYNOPSIS
HIGH PRESSURE EXTENDING FROM THE WESTERN ATLANTIC TO
THE NORTHERN GULF WILL CHANGE LITTLE DURING THE FORECAST PERIOD.
THE PRESSURE GRADIENT BETWEEN IT AND RELATIVELY LOWER PRESSURES
OVER TEXAS AND NORTHERN MEXICO WILL GENERALLY MAINTAIN A GENTLE
TO MODERATE EAST TO SOUTHEAST WIND FLOW ACROSS THE BASIN THROUGH
THE WEEKEND, WITH THE EXCEPTION OF FRESH TO STRONG WINDS PULSING
OFF NW YUCATAN FROM THE LATE AFTERNOONS AND INTO THE NIGHT TIME
HOURS. A SERIES OF UPPER-LEVEL DISTURBANCES MOVING THROUGH A
VERY MOIST AND UNSTABLE ENVIRONMENT ARE EXPECTED TO KEEP
UNSETTLED WEATHER CONDITIONS IN THE FORM OF LARGE THUNDERSTORM
COMPLEXES THAT WILL BE MOVING ENE ACROSS THE NW AND WEST-CENTRAL
GULF SECTIONS DURING THE NEXT FEW DAYS. MARINERS TRANSITING
THROUGH THESE WATERS SHOULD CHECK THE LATEST FORECAST AND WEATHER
CONDITIONS PRIOR TO BEGINNING OR CONTINUING THEIR TRANSITS.
