FRESH TO STRONG NW TO N WINDS ARE EVIDENT ACROSS THE GULF OF
CALIFORNIA DUE TO THE PRESENCE OF A STRONG 1043 MB HIGH PRESSURE
OVER THE GREAT BASIN. SEAS ARE 6 TO 8 FT WITHIN THESE WIND
SPEEDS. LOW PRESSURE WELL W OF THE REVILLAGIGEDO ISLANDS IS
CAUSING WINDS IN THE VICINITY OF THOSE ISLANDS AS WELL AS THE
OUTER OFFSHORE WATERS OF BAJA CALIFORNIA TO INCREASE OUT OF THE
SOUTHEAST TO MODERATE TO FRESH, AND SCATTERED MODERATE CONVECTION
IS DEVELOPING. ELSEWHERE, MAINLY GENTLE WINDS ARE PRESENT. SEAS
ACROSS OFFSHORE WATERS ARE MODERATE, IN MAINLY NW SWELL.
FOR THE FORECAST, ASIDE FROM THE STORM CONDITIONS OVER THE GULF
OF TEHUANTEPEC, HIGH PRESSURE OVER THE GREAT BASIN WILL WEAKEN
AND MOVE EAST TONIGHT, CAUSING WINDS AND SEAS IN THE GULF OF
CALIFORNIA TO DIMINISH INTO WED. LOW PRESSURE WILL MOVE NORTHWARD
WEST OF THE WATERS OFFSHORE BAJA CALIFORNIA, BRINGING FRESH SE
WINDS AND SHOWERS AND THUNDERSTORMS TO THOSE WATERS INTO WED.
LONG PERIOD NW SWELL MAY BRING ROUGH SEAS TO WATERS OFFSHORE BAJA
CALIFORNIA NORTE THIS WEEKEND.
