GULF OF TEHUANTEPEC GALE WARNING: THE PRESSURE GRADIENT BETWEEN
HIGH PRESSURE OVER THE EASTERN SLOPES OF MEXICO AND LOWER
PRESSURE WITHIN THE EASTERN NORTH PACIFIC MONSOON TROUGH IS
SUPPORTING GALE- FORCE GAP WINDS IN THE GULF OF TEHUANTEPEC. THE
AREA OF HIGH PRESSURE WILL WEAKEN TONIGHT, WHICH WILL LOOSEN THE
PRESSURE GRADIENT AND DIMINISH WINDS BELOW GALE FORCE. VERY
ROUGH SEAS, PEAKING AROUND 12 OR 13 FT, WILL START TO SUBSIDE
TONIGHT AS THE WINDS DIMINISH. PLEASE READ THE LATEST HIGH SEAS
ISSUED BY THE NATIONAL HURRICANE CENTER AT WEBSITE:
HTTPS://WWW.NHC.NOAA.GOV/TEXT/MIAHSFEP2.SHTML FOR MORE
INFORMATION.
ASIDE FROM CONDITIONS IN THE GULF OF TEHUANTEPEC, A RIDGE
EXTENDS FROM HIGH PRESSURE LOCATED N OF THE AREA TO ACROSS THE
OFFSHORE FORECAST WATERS OF BAJA CALIFORNIA. THE PRESSURE
GRADIENT BETWEEN THIS RIDGE AND A TROUGH OVER WESTERN MEXICO IS
SUPPORTING MODERATE TO FRESH WINDS OVER THE GULF OF CALIFORNIA.
GENTLE TO MODERATE WINDS ARE OVER THE WATERS NEAR THE
REVILLAGIGEDO ISLANDS. LIGHT TO GENTLE WINDS AND MODERATE SEAS IN
LONG PERIOD NW SWELL ARE NOTED ACROSS THE REMAINDER OF THE
MEXICAN OFFSHORE WATERS.
FOR THE FORECAST, GALE-FORCE NORTHERLY GAP WINDS IN THE GULF OF
TEHUANTEPEC WILL DIMINISH TONIGHT, WITH FRESH TO STRONG WINDS
CONTINUING THOUGH THE END OF THE WEEK. WINDS OVER TEHUANTEPEC
WILL DIMINISH ON SATURDAY BEFORE STRENGTHENING AGAIN ON SUNDAY.
FRESH N WINDS MAY DEVELOP NEAR CABO CORRIENTES TONIGHT THROUGH
WED NIGHT.

FOR THE FORECAST, MAINLY GENTLE WINDS WILL PREVAIL N OF THE
MONSOON TROUGH OVER THE NEXT SEVERAL DAYS, EXCEPT PULSING TO
MODERATE TO FRESH IN THE GULF OF PAPAGAYO, LOCALLY STRONG AT
TIMES. GENTLE TO MODERATE WINDS WILL PREVAIL S OF MONSOON TROUGH.
MODERATE N WINDS WILL PULSE IN THE GULF OF PANAMA STARTING
TONIGHT. SEAS ACROSS THE OUTER OFFSHORE WATERS OF EL SALVADOR AND
GUATEMALA, GENERATED BY A GALE-FORCE GAP WIND EVENT IN THE GULF
OF TEHUANTEPEC, WILL SUBSIDE TONIGHT. OTHERWISE, MODERATE SEAS IN
MIXED SW AND NW SWELL ARE EXPECTED OVER THE REGIONAL WATERS
THROUGH THE WEEK AND INTO NEXT WEEKEND.
