A BROAD RIDGE OVER THE SOUTHERN UNITED STATES IS FORCING FRESH
TO NEAR GALE-FORCE NORTHERLY WINDS AND MODERATE TO LOCALLY ROUGH
SEAS ACROSS THE GULF OF TEHUANTEPEC. MODERATE TO LOCALLY FRESH
NE-E WINDS AND MODERATE SEAS ARE EVIDENT IN THE FAR OFFSHORE
WATERS OF OAXACA. MEANWHILE, THE REMAINDER OF THE OFFSHORE
WATERS OF MEXICO ARE UNDER THE INFLUENCE OF A 1019 MB HIGH
PRESSURE SYSTEM NEAR 30N125W THAT EXTENDS A RIDGE TO THE
REVILLAGIGEDO ISLANDS. GENTLE TO MODERATE NORTHERLY WINDS AND
MODERATE SEAS ARE FOUND OFF BAJA CALIFORNIA NORTE AND THE
SOUTHERN GULF OF CALIFORNIA. LIGHT TO GENTLE WINDS AND SLIGHT TO
MODERATE SEAS ARE NOTED IN THE REMAINDER OF THE GULF OF
CALIFORNIA AND BAJA CALIFORNIA SUR. ELSEWHERE, MODERATE OR
WEAKER WINDS AND MODERATE SEAS PREVAIL.
FOR THE FORECAST, THE HIGH PRESSURE NORTH OF THE AREA WILL
SUPPORT FRESH TO NEAR GALE-FORCE NORTHERLY WINDS AND MODERATE TO
LOCALLY ROUGH SEAS THROUGH LATE THIS WEEK. WINDS ARE EXPECTED TO
PULSE TO GALE-FORCE AT NIGHT FROM MON THROUGH WED AND TO NEAR
GALE THU. ROUGH SEAS WILL DEVELOP WITH THESE WINDS. ELSEWHERE
OVER THE MAJORITY OF THE WATERS, A RELATIVELY WEAK PRESSURE
GRADIENT WILL LEAD TO MODERATE OR WEAKER WINDS AND SEAS INTO THE
EARLY PART OF THE UPCOMING WEEK. LOOKING AHEAD, A COLD FRONT WILL
BE WEST OF THE BAJA CALIFORNIA NORTE OFFSHORE WATERS BY THE
MIDDLE PART OF THE WEEK. THE LEADING EDGE OF A NORTHWEST SWELL
SET PROPAGATING OUT AHEAD OF THE FRONT WILL BEGIN TO IMPACT THE
WESTERN PART OF THE OFFSHORE WATERS NORTH OF PUNTA EUGENIA ON
WED, AND THE ENTIRE OFFSHORE WATERS NORTH OF THAT SAME LOCATION
BY FRI BUILDING SEAS THERE TO JUST BELOW 12 FT.
