BASED ON SATELLITE IMAGERY...WEATHER OBSERVATIONS...RADAR...AND 
METEOROLOGICAL ANALYSIS.

BASED ON 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
UTC.
 
...TROPICAL WAVES...
TROPICAL WAVE N OF 3N ALONG 81W IS MOVING W AT 10-15 KT. 
SCATTERED MODERATE ISOLATED STRONG CONVECTION LIES ALONG THE

THERE IS AN AREA OF SCATTERED MODERATE ISOLATED STRONG  
CONVECTION CENTERED NEAR 13N93W IN ASSOCIATION WITH A 1010 MB 
LOW PRESSURE. VISIBLE SATELLITE IMAGERY INDICATES WELL DEFINED 
CYCLONIC TURNING IN THE LOW AND MID LEVEL CLOUDS. A SHIP WITH 
CALL SIGN A8CC4 CENTERED 130 NM W OF THE LOW REPORTED N WINDS 
OF 20 KT.

...DISCUSSION...

W OF 110W...
SHARP UPPER LEVEL TROUGH EXTENDS FROM SRN CALIFORNIA SWWD 
THROUGH 30N125W 22N133W TO 16N140W AND WAS ACCOMPANIED BY STRONG 
UPPER LEVEL SUBSIDENCE AT THE SOUTHERN END OF THE TROUGH AND E 
OF THE TROUGH AXIS TO 112W INCLUDING THE BAJA PENINSULA AND NW 
MEXICO. NARROW UPPER LEVEL RIDGE AXIS WAS INDICTED TO THE W OF 
THE TROUGH AXIS OVER THE FAR NW CORNER OF THE DISCUSSION AREA. 
MODERATE ELY FLOW WAS NOTED OVER THE TROPICS S OF 18N AND E OF 
120W. THIS FLOW WAS ADVECTING SOME MID TO UPPER LEVEL MOISTURE 
WWD TO ALONG 118W. AT THE SURFACE...RIDGE OF HIGH PRESSURE 
DOMINATED THE AREA N OF 12N AND W OF 110W. 

E OF 110W...
FAIRLY LARGE MID TO UPPER LEVEL ANTICYCLONE NEAR 22N105W 
DOMINATED THE FLOW OVER MEXICO AND THE E PACIFIC BETWEEN 90W AND 
110W. MODERATE NE FLOW ALOFT WAS ADVECTING COPIOUS AMOUNTS OF 
MID TO UPPER LEVEL MOISTURE WWD ACROSS THE TROPICAL E PACIFIC W 
OF 80W. A SHARP DELINEATION EXISTED BETWEEN THIS AREA OF DEEP 
MOISTURE AND AN AREA OF STRONG UPPER LEVEL SUBSIDENCE OVER THE 
GULF OF MEXICO AND THE BAY OF CAMPECHE. THE AREA OF SUBSIDENCE 
OVER THE BAY OF CAMPECHE WAS PRESSING SWD ACROSS THE ISTHMUS OF 
TEHUANTEPEC. AT THE SURFACE...1008 MB LOW NEAR 14N104W WAS 
DRIFTING WWD AND WAS ACCOMPANIED BY A PATCH OF SCATTERED 
MODERATE CONVECTION. ELSEWHERE CROSS EQUATORIAL SLY WINDS 
CONTINUE TO ACCELERATE TOWARD LOWER PRESSURE S OF 12N BETWEEN 
90W AND 110W.
