SYNOPSIS FOR THE GULF OF AMERICA
1030 AM 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 IN A VERY MOIST AND
UNSTABLE ENVIRONMENT IS 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.
