...DISCUSSION...

A DEEP LOW HAS BEEN MOVING SLOWLY SOUTHEASTWARD JUST NORTH OF 
THE AREA AND IS CURRENTLY AT 34N132W.  AN ASSOCIATED COLD 
FRONTAL BOUNDARY REACHES INTO OUR AREA ALONG 30N128W TO 
23W140W.  THE ASSOCIATED CONVECTION WITH THE FRONT HAS BEEN 
DIMINISHING THIS EVENING AND IS PRIMARILY NORTH OF OUR AREA AS 
OBSERVED FROM IR IMAGERY AND LIGHTNING DATA.  THE LOW SHOULD 
BEGIN MOVING MORE EASTWARD AS THE FRONTAL BOUNDARY WEAKENS IN 
THE NEXT DAY.  ELSEWHERE IN THE UPPER LEVELS...A LARGE RIDGE IS 
CENTERED NEAR 14N104W.  STRONG UPPER SW FLOW...UP TO 90 KT OVER 
BAJA CALIFORNIA AND STRONGER FARTHER NORTH...BETWEEN THE DEEP 
LOW AND THE UPPER RIDGE IS PROVIDING SUBSTANTIAL UPPER LEVEL 
MOISTURE AND CIRRUS COVER OVER BAJA CALIFORNIA AND NW MAINLAND 
MEXICO.  ADDITIONALLY...UPPER MOISTURE IS BEING ADVECTED INTO 
THE WESTERN PORTION OF OUR REGION BETWEEN 10N AND 22N AFTER 
BEING GENERATED FROM THE ITCZ IN OUR REGION AND SOUTH OF 
HAWAII.  THE ITCZ IN OUR AREA IS SOMEWHAT MORE ACTIVE TODAY WITH 
MORE SUBSTANTIAL CONVECTION OCCURRING BETWEEN 108W AND 130W.

NO SURFACE GALES ARE CURRENTLY OCCURRING IN THE REGION...NOR ARE 
THERE ANY LIKELY TO OCCUR IN THE NEXT FEW DAYS.  THE ONLY REGION 
CURRENTLY WITH AT LEAST 20 KT WINDS EXIST ALONG THE EAST SIDE OF 
THE AFOREMENTIONED COLD FRONT.  IN ABOUT 36 HOURS...20 KT N TO 
NW WINDS WILL DEVELOP JUST WEST OF SOUTHERN BAJA CALIFORNIA.  
THESE WILL SPREAD INTO THE SOUTHERN GULF OF CALIFORNIA AND 
PERSIST UNTIL FRIDAY NIGHT.  THESE 20 TO 25 KT NW WINDS ON 
THURSDAY AND FRIDAY SHOULD CAUSE AN INCREASE IN LOCAL WINDS 
WAVES IN THE SOUTHERN GULF OF CALIFORNIA.  NO SIGNIFICANT GAP 
WIND EVENTS SHOULD OCCUR IN THE NEXT FEW DAYS.
