...DISCUSSION...
  
A 1029 MB SURFACE HIGH CENTER LOCATED NEAR 32N133W EXTENDS A
RIDGE AXIS SE TO 17N106W. A WEAKENING COLD FRONT IS MOVING S
INTO THE CENTRAL GULF OF CALIFORNIA. FRESH TO MODERATE
NORTHWESTERLY WINDS ARE FOLLOWING THE FRONT ACROSS THE GULF. THE
FRONT SHOULD DISSIPATE TONIGHT. ANOTHER COLD FRONT IS FORECAST
TO MOVE ACROSS THE SAME AREA WEDNESDAY NIGHT WITH SIMILAR
CONDITIONS EXPECTED WEDNESDAY NIGHT INTO EARLY THURSDAY...WITH
THE FRONT STALLING OUT THROUGH THE END OF THE WEEK ALLOWING FOR
THE UNSETTLED CONDITIONS TO PERSIST ON THURSDAY. THE FRONT
FINALLY DISSIPATES AND SHIFTS EASTWARD THURSDAY NIGHT INTO
FRIDAY MORNING WITH MORE TRANQUIL CONDITIONS EXPECTED FOR THE
NORTHERN GULF THEREAFTER.

THE RIDGING COMBINED WITH ELONGATED TROUGHING ACROSS NW MEXICO
IS RESULTING IN A TIGHT PRESSURE GRADIENT W OF THE BAJA
CALIFORNIA PENINSULA...WITH FRESH TO STRONG NW TO N FLOW
EXTENDING SOUTHWARD TO 25N OFFSHORE OF THE PENINSULA. STRONGER

THESE WINDS ARE SUPPORTING FRESH 8 TO 11 FT NW SWELL SOUTH OF
30N. THE WINDS WILL DIMINISH THROUGH TONIGHT WITH A NEW SURGE
ANTICIPATED WEDNESDAY NIGHT AS THE NEXT COLD FRONT MOVES IN FROM
THE NW-N. THIS NEXT ROUND OF WINDS WILL THEN DIMINISH THURSDAY
NIGHT THROUGH SATURDAY. 

NO SIGNIFICANT GAP WIND EVENTS ARE OCCURRING NOR ARE LIKELY TO
BEGIN DURING THE NEXT SEVERAL DAYS.

CROSS-EQUATORIAL SW SWELLS WILL REACH THE EQUATOR LATE WEDNESDAY
WITH COMBINED SEAS OF 6-9 FT. THE LEADING EDGE OF THIS SWELL
TRAIN WILL ARRIVE AT THE SW FACING SHORES OF THE GALAPAGOS THU
NIGHT...THEN REACHING THE SHORES OF CENTRAL AMERICA FRIDAY
EVENING.
  
MODERATE TO FRESH NE TRADES GENERALLY BETWEEN 07N AND 20W WEST
