A COLD FRONT ASSOCIATED TO AN INTENSE STORM CENTER LOCATED WELL
NORTH OF THE AREA EXTENDS FROM NEAR 30N123W SOUTHWESTWARD TO
25N130W AND TO 23N140W. FRESH TO STRONG WINDS ARE ON EITHER SIDE
OF THE FRONT NORTH OF 29N WEST OF 120W. SEAS WITH THESE WINDS ARE
IN THE 8 TO 12 FT RANGE, EXCEPT FOR HIGHER SEAS OVER THE AREA AS
DESCRIBED ABOVE UNDER THE SPECIAL FEATURES SECTION. TO THE
SOUTHEAST OF THE FRONT, A WEAK 1018 MB HIGH IS ANALYZED AT
25N116W. LIGHT TO GENTLE WINDS ARE NEAR THIS HIGH CENTER. SOUTH
OF PUNTA EUGENIA, MODERATE TO LOCALLY FRESH NORTHWEST TO NORTH
WINDS CONTINUE INSIDE THE GULF OF CALIFORNIA, WHERE SEAS ARE 2 TO
4 FT, AND GENTLE TO MODERATE N TO NE WINDS PREVAIL ACROSS THE
WATERS OF BAJA SUR AND EXTEND INTO THE REVILLAGIGEDO ISLANDS.
NORTHWEST WELL BUILDING ACROSS THE AREA IS PRODUCING SEAS OF 6 TO
9 FT ACROSS THE BAJA NORTE WATERS AND 4 TO 6 FT SOUTH OF PUNTA
EUGENIA. HIGH PRESSURE NORTH OF THE REGION CENTERED ACROSS THE
NORTHERN GULF OF AMERICA AND NORTHERN MEXICO WILL SLOWLY WEAKEN
AND REMAIN RELATIVELY STATIONARY INTO SAT, WHICH WILL MAINTAIN
STRONG GAP WINDS ACROSS AND DOWNWIND OF TEHUANTEPEC THROUGH THAT
TIME. WINDS MAY REACH JUST BELOW GALE-FORCE TONIGHT, AND THEN
SLOWLY WEAKEN EACH DAY THROUGH SAT. SEAS OF 8 TO 10 FT ARE
CURRENTLY DOWNSTREAM OF THE GULF OF TEHUANTEPEC REACH TO NEAR
14N. THESE SEAS WILL SLOWLY SUBSIDE GOING INTO SAT. OTHERWISE,
GENTLE TO LOCALLY MODERATE NORTHWEST TO NORTH WINDS PREVAIL
ELSEWHERE ACROSS THE MEXICAN WATERS BETWEEN PUERTO ANGEL AND BAJA
SUR, WHERE SEAS ARE 3 TO 5 FT. WAVES GENERATED ACROSS THE GULF
OF TEHUANTEPEC ARE PRODUCING SEAS OF 5 TO 7 FT ACROSS THE OUTER
OFFSHORE WATERS WELL OFFSHORE OF TEHUANTEPEC.
FOR THE FORECAST, HIGH PRESSURE ACROSS THE GULF OF AMERICA WILL
CONTINUE TO INDUCE STRONG NORTHERLY GAP WINDS ACROSS THE GULF OF
TEHUANTEPEC, GRADUALLY DIMINISHING EACH DAY THROUGH SAT. GALE
CONDITIONS MAY BE POSSIBLE IN THE GULF OF TEHUANTEPEC REGION TUE
NIGHT. NORTHWEST SWELL PROPAGATING THROUGH THE WATERS NORTH OF
PUNTA EUGENIA WILL BE REINFORCED BY A NEW SET OF NORTHWEST SWELL
BUILDING INTO THE REGIONAL WATERS TODAY INTO FRI NIGHT, SPREADING
ROUGH SEAS SOUTHWARD ACROSS THE OFFSHORE WATERS OF THE BAJA
CALIFORNIA PENINSULA THROUGH THE UPCOMING WEEKEND. HIGH PRESSURE
WILL BEGIN TO BUILD ACROSS THE BAJA WATERS FRI NIGHT THROUGH THE
UPCOMING WEEKEND TO BRING 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.
