...DISCUSSION...
THE NE PACIFIC IS DOMINATED BY A STRONG 1035 MB HIGH JUST NW OF 
OUR REGION AT 35N150W. THERE IS A TIGHT PRES GRADIENT IN PLACE 
BETWEEN THIS HIGH AND TROUGHING FROM THE SW U.S. THROUGH CENTRAL 
MEXICO...PRODUCING FRESH TO STRONG NW TO N WINDS FROM OFFSHORE 
OF CENTRAL CALIFORNIA...WHERE AN AREA OF GALE FORCE WINDS IS 
FOUND...TO ALONG THE W COAST OF BAJA CALIFORNIA. THIS STRONG 
PRES GRADIENT OVER NE WATERS WILL BE MAINTAINED THE NEXT FEW 
DAYS. LOOK FOR FRESH TO STRONG NE TRADE WINDS BETWEEN THE HIGH 
AND THE ITCZ TO REMAIN IN PLACE GENERALLY W OF 127W THROUGH 
MON.  

EARLY MONDAY MORNING...20 TO 25 KT NW SURFACE WINDS SHOULD 
COMMENCE OVER THE NORTHERN GULF OF CALIFORNIA. THESE WINDS 
SHOULD CONTINUE UNTIL TUESDAY.

THE REMAINDER OF THE AREA HAS LESS THAN 20 KT WINDS BUT IS 
OVERSPREAD BY 8 TO 11 FT S TO SW SWELL FROM THE SOUTHERN 
HEMISPHERE. THIS MODERATE SWELL SHOULD CONTINUE FOR AT LEAST THE 
NEXT FEW DAYS.
