A RECENT SCATTEROMETER SATELLITE PASS CAPTURED FRESH TO NEAR
GALE-FORCE NORTHERLY WINDS ACROSS THE GULF OF TEHUANTEPEC DUE TO
A SUBTROPICAL RIDGE NORTH OF THE AREA. SEAS IN THESE WATERS ARE
5-8 FT. FARTHER WEST, A STRONG GALE CENTER NEAR CALIFORNIA
SUSTAINS A LARGE AREA OF NW SWELL THAT IS PRODUCING SEAS OF 6-10
FT NORTH OF PUNTA EUGENIA, ESPECIALLY WEST OF GUADALUPE ISLAND.
MEANWHILE, MODERATE TO FRESH NW WINDS AND MODERATE SEAS ARE FOUND
IN 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 RELATED TO HIGH PRESSURE OVER THE
GULF OF AMERICA WILL CONTINUE TO INDUCE FRESH TO STRONG NORTHERLY
GAP WINDS AND LOCALLY ROUGH SEAS IN THE GULF OF TEHUANTEPEC
REGION THROUGH SAT MORNING, THEN GRADUALLY DIMINISHING THROUGH
SAT AFTERNOON AS THE HIGH PRESSURE SLOWLY WEAKENS. GALE CONDITIONS
MAY BE POSSIBLE IN THE GULF OF TEHUANTEPEC REGION STARTING 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.
