FRESH TO STRONG NORTH WINDS ARE IN THE GULF OF TEHUANTEPEC
SUPPORTED BY THE RESULTANT PRESSURE GRADIENT BETWEEN A HIGH
PRESSURE SYSTEM OVER CENTRAL UNITED STATES EXTENDING A RIDGE TO
THE NORTHERN GULF OF AMERICA, AND LOWER PRESSURE ASSOCIATED TO
THE MONSOON TROUGH SOUTH OF THE AREA. SEAS OVER THESE WATERS ARE
5 TO 7 FT. MEANWHILE, THE PRESSURE GRADIENT BETWEEN A COLD FRONT
APPROACHING BAJA CALIFORNIA NORTE FROM THE NW AND HIGH PRESSURE
OVER NEW MEXICO IS SUPPORTING MODERATE TO FRESH NW WINDS AND
ROUGH SEAS OF 8 TO 12 FT WITH A PERIOD OF 8 TO 12 SECONDS IN NW
SWELL ACROSS THE BAJA CALIFORNIA OFFSHORE WATERS. A PRE-FRONTAL
TROUGH SUPPORTS FRESH TO STRONG SW WINDS OVER THE NORTHERN GULF
OF CALIFORNIA WITH SEAS TO 5 FT, AND MODERATE OR WEAKWER WINDS
WITH SEAS TO 3 FT ELSEWHERE ALONG THE REMAINDER GULF. A WEAK
PRESSURE GRADIENT PRESENT ACROSS THE REMAINDER OF THE MEXICAN
OFFSHORE WATERS IS GENERALLY ALLOWING FOR MAINLY LIGHT TO GENTLE
WINDS AND SLIGHTLY LOWER SEAS OF 5 TO 7 FT.
FOR THE FORECAST, FRESH TO STRONG NORTHERLY WINDS AND ROUGH SEAS
AROUND 8 FT WILL CONTINUE OVER THE GULF OF TEHUANTEPEC INTO
EARLY ON SAT. THE NEXT TEHUANTEPEC GAP WIND EVENT IS FORECAST TO
BEGIN BY MON EVENING, AND CONTINUE THROUGH MUCH OF THE NEXT WEEK.
WINDS THERE MAY REACH GALE-FORCE STARTING LATE TUE AND POSSIBLY
CONTINUE THROUGH MOST OF THE PERIOD THROUGH WED NIGHT. FRESH
NW WINDS W OF BAJA CALIFORNIA N OF PUNTA EUGENIA WILL DIMINISH
ON SAT. VERY ROUGH SEAS FROM AN EXPANSIVE SET OF NW SWELL OVER
THESE WATERS WILL PEAK TO AROUND 20 FT SAT NIGHT BEFORE GRADUALLY
SUBSIDING AFTERWARD. FRESH TO LOCALLY STRONG WINDS IN THE
NORTHERN GULF OF CALIFORNIA WILL DIMINISH BY EARLY SAT. ANOTHER
RATHER EXPANSIVE SET OF NW SWELL EXPECTED ON SAT SHOULD BUILD
SEAS TO AROUND 19 FT OVER THE OUTER OFFSHORE WATERS OF BAJA
CALIFORNIA NORTE. ROUGH SEAS WILL REACH ALL THE WAY TO PAST 100W,
WHILE ADDITIONAL AND REINFORCING NW SWELL SETS CONTINUE TO
ARRIVE.
