THE EQUATOR TO 32N...EAST OF 140W.

BASED ON 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
2030 UTC.

...ITCZ...
AXIS IS ALONG 11N85W 8N97W TO A 1012 MB LOW NEAR 10N106W TO A 
1011 MB LOW NEAR 11N124W TO 8N140W. SCATTERED MODERATE/ISOLATED 
STRONG CONVECTION IS NEAR THE 1012 MB LOW FROM 9N-11N BETWEEN 
104W-110W. 

...DISCUSSION...
SHARP UPPER TROUGH IS OVER THE W PORTION OF THE REGION EXTENDING 
THROUGH 32N129W TO 21N138W SUPPORTING COLD FRONT ENTERING THE 
REGION THROUGH 32N126W SW TO 25N137W BECOMING STATIONARY TO 
BEYOND 22N140W WITH ISOLATED SHOWERS WITHIN 60 NM E OF THE COLD 
FRONT. STRONG NORTHERLY WINDS ARE W OF THE FRONT WITH LARGE NW 
SWELL CONTINUING TO PROPAGATE SE ACROSS THE AREA W OF 110W. COLD 
AIR STRATOCUMULUS CLOUDS ARE W OF THE FRONT AS WELL AS A 
SURFACE RIDGE THAT IS BUILDING EASTWARD ANCHORED JUST W OF THE 
REGION BY A 1026 MB HIGH. TO THE E OF THE UPPER TROUGH IS A 
LARGE AMPLITUDE UPPER RIDGE EXTENDING FROM AN UPPER HIGH NEAR 
15N124W NNE TO OVER SOUTHERN CALIFORNIA WITH MODERATE/STRONG 
SUBSIDENCE AND DRY STABLE AIR ALOFT N OF 15N E OF 120W TO OVER 
THE BAJA PENINSULA. A BROAD UPPER TROUGH EXTENDS S OVER MEXICO  
AND THE GULF OF MEXICO SUPPORTING A STRONG COLD FRONT THE IS 
CURRENTLY EXTENDS S INTO THE CARIBBEAN TO OVER CENTRAL AMERICA. 
THIS FEATURE IS RESPONSIBLE FOR PRODUCING STORM FORCE WINDS INTO 
THE GULF OF TEHUANTEPEC. NOW THAT THE FRONT HAS COMPLETELY 
CLEARED THE GULF OF MEXICO THESE WINDS ARE EXPECTED TO 
DIMINISHED TO GALE FORCE IN THE NEXT FEW HOURS.
