SYNOPSIS FOR THE GULF OF AMERICA
504 PM EDT SAT MAY 23 2026
SYNOPSIS
HIGH PRESSURE EXTENDING FROM THE WESTERN ATLANTIC TO
THE NORTHERN GULF WILL CHANGE LITTLE THROUGH LATE MON, THEN
WEAKEN FOR THE REMAINDER OF THE WEEK. THE RELATED PRESSURE
GRADIENT WILL MAINTAIN A GENTLE TO MODERATE EAST TO SOUTHEAST WIND
FLOW THROUGH EARLY SUN, EXCEPT FOR LIGHT TO GENTLE SOUTHEAST
WINDS W OF ABOUT 94W TONIGHT THROUGH TUE AS A WEAK TROUGH DEVELOPS
OFF THE TEXAS COAST. WINDS THEN GENERALLY BECOME SOUTHEAST AT
GENTLE TO MODERATE SPEEDS ACROSS THE BASIN THROUGH MIDWEEK, WITH
SLIGHT TO MODERATE SEAS, WITH THE EXCEPTION OF FRESH TO STRONG
WINDS PULSING OFF NW YUCATAN FROM THE LATE AFTERNOONS AND INTO THE
NIGHT TIME HOURS DUE TO LOCAL EFFECTS ASSOCIATED WITH A THERMAL
TROUGH. SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS OVER THE
NW AND NORTHERN GULF W OF 89W ARE CAPABLE OF PRODUCING FREQUENT
LIGHTNING, GUSTY WINDS AND HEAVY RAINFALL REDUCING VISIBILITY.
THIS ACTIVITY WILL CONTINUE INTO TONIGHT. ADDITIONAL ACTIVITY
IS LIKELY TO DEVELOP AGAIN LATE TONIGHT INTO EARLY SUN. IN ADDITION,
INCREASING MOISTURE OVER THE SOUTHEASTERN GULF BEGINNING AROUND THE
MIDDLE PORTION OF THE UPCOMING WEEK SHOULD LEAD TO INCREASING CHANCES
FOR UNSETTLED WEATHER IN THAT PART OF THE GULF. MARINERS ARE URGED
TO KEEP UP WITH THE LATEST FORECAST.
