A 1021 MB HIGH IS CENTERED N OF THE DISCUSSION AREA NEAR 35N131W
AND EXTENDS A RIDGE AXIS SE ACROSS THE NORTHERN WATERS TO
13N100W. AN AREA OF WEAK SURFACE TROUGHING IS NOTED TO THE S-SE
OF THE RIDGE IN THE VICINITY OF 07N121W. WHILE CONVECTION HAS
DIMINISHED IN ASSOCIATION WITH THIS AREA OF TROUGHING...MODERATE
TO OCCASIONAL FRESH TRADES ARE GENERATING SEAS OF 8 FT ACROSS AN
AREA FROM 05N TO 10N BETWEEN 117W AND 122W WHICH IS EXPECTED TO
DRIFT WESTWARD THROUGH FRI. THE HIGH WILL MOVE SOUTHWARD TO A
POSITION NEAR 29N129W IN 18 TO 24 HOURS AS A COLD FRONT
APPROACHES THE FAR NW CORNER TONIGHT.

THE COLD FRONT WILL ENTER THE NW CORNER OF THE FORECAST REGION
TONIGHT WITH INCREASING SOUTHERLY WINDS AND BUILDING SEAS ACROSS
THE NW WATERS. UPDATED GRIDS SUGGESTS A BRIEF PERIOD OF S TO SW
WINDS IN THE 20-25 KT RANGE AND BUILDING SEAS OF 8-11 FT N OF

SWELL GENERATED BY THE TRADES...AND CROSS-EQUATORIAL SW SWELL.

A LOCALLY TIGHT PRESSURE GRADIENT IS EXPECTED TO DEVELOP IN THE
PACIFIC WATERS OFF THE COAST OF SOUTHERN BAJA CALIFORNIA ON THU.
AS A RESULT...NW WINDS FUNNELING ALONG THE SOUTHERN TIP OF THE
BAJA PENINSULA WILL INCREASE TO FRESH TO STRONG LEVELS. SEAS
WILL BUILD TO 8 FT AS THESE WINDS INCREASE.

CROSS EQUATORIAL SW SWELL WILL CONTINUE TO PROPAGATE ACROSS THE
S-CENTRAL WATERS DURING THE NEXT 24-36 HOURS WITH SEAS OF 8-9 FT
