WARNINGS
.NONE.
LATEST SCATTEROMETER SATELLITE DATA INDICATES FRESH TO STRONG
NORTH WINDS IN THE GULF OF TEHUANTEPEC REGION DUE TO THE GRADIENT
ASSOCIATED TO A SUBTROPICAL RIDGE NORTH OF THE AREA. SEAS OVER
THESE WATERS ARE IN 5 TO 7 FT. FARTHER WEST, A LARGE AREA OF
NORTHWEST SWELL IS GENERATING SEAS OF 7 TO 11 FT NORTH OF PUNTA
EUGENIA, ESPECIALLY WEST OF GUADALUPE ISLAND. MEANWHILE, MODERATE
TO FRESH NORTHWEST WINDS AND MODERATE SEAS ARE OVER THE CENTRAL
AND SOUTHERN GULF OF CALIFORNIA AND OFF BAJA CALIFORNIA SUR.
ELSEWHERE, MODERATE OR WEAKER WINDS AND SLIGHT TO MODERATE SEAS
PREVAIL.
FOR THE FORECAST, THE GRADIENT ASSOCIATED TO HIGH PRESSURE OVER

NORTHERLY GAP WINDS AND MODERATE TO LOCALLY ROUGH SEAS IN THE
GULF OF TEHUANTEPEC REGION THROUGH SAT MORNING, THEN DIMINISH IN
THE EARLY AFTERNOON. GALE CONDITIONS MAY BE POSSIBLE IN THE GULF
OF TEHUANTEPEC REGION STARTING LATE MON NIGHT. NORTHWEST SWELL
PROPAGATING THROUGH THE WATERS NORTH OF PUNTA EUGENIA WILL BE
SPREADING ROUGH SEAS SOUTHWARD ACROSS THE OFFSHORE WATERS OF THE
BAJA CALIFORNIA PENINSULA THROUGH THE WEEKEND. HIGH PRESSURE WILL
BEGIN TO BUILD ACROSS THE BAJA WATERS THROUGH THE WEEKEND
BRINGING A RETURN TO MORE TYPICAL NORTHERLY WINDS. FRESH TO
LOCALLY STRONG NORTHWEST WINDS ARE LIKELY TO DEVELOP IN THE GULF
OF CALIFORNIA SUN INTO TUE AS HIGH PRESSURE STRENGTHENS ACROSS
THE REGION.

OF 28N AND BETWEEN 126W AND 137W. WAVE PERIOD WITH THESE SEAS
