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
NORTHWEST WINDS WEST OF BAJA CALIFORNIA NORTH OF PUNTA EUGENIA
WILL DIMINISH ON SAT. VERY ROUGH SEAS FROM AN EXPANSIVE SET OF
NORTHWEST 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 NORTHWEST 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 NORTHWEST SWELL SETS
CONTINUE TO ARRIVE.
FRESH TO STRONG NORTH WINDS ARE IN THE GULF OF TEHUANTEPEC
SUPPORTED BY THE RESULTANT PRESSURE GRADIENT BETWEEN A HIGH
PRESSURE SYSTEM OVER SOUTHERN UNITED STATES AND MEXICO, AND LOWER
PRESSURE ASSOCIATED TO THE MONSOON TROUGH SOUTH OF THE AREA. A
RECENT ASCAT SCATTEROMETER DATA PASS NICELY CAPTURED THESE WINDS.
SEAS OVER THESE WATERS ARE 6 TO 8 FT. MEANWHILE, A WEAK PRESSURE
GRADIENT THAT IS PRESENT ACROSS THE REMAINDER OF THE MEXICAN
OFFSHORE WATERS IS GENERALLY ALLOWING FOR MAINLY LIGHT TO GENTLE
WINDS. RECENT ALTIMETER SATELLITE DATA PASSES REVEAL SEAS OF 6 TO 8
FT IN SUBSIDING NORTHWEST SWELL OVER THE WATERS SOUTH OF PUNTA
EUGENIA AND EAST TO NEAR 107W. SLIGHTLY LOWER SEAS OF 5 TO 7 FT ARE
ELSEWHERE OVER THE MEXICAN OFFSHORE WATERS OUTSIDE THE GULF OF
TEHUANTEPEC REGION. NORTH OF PUNTA EUGENIA, ROUGH SEAS IN THE RANGE
OF 8 TO 13 FT ARE PRESENT AS A NEW SET OF LONG-PERIOD NW SWELL
CONTINUES TO PROPAGATE THROUGH THE WATERS WEST OF BAJA CALIFORNIA
NORTE.
