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

BASED ON 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
0845 UTC.

...SPECIAL FEATURE...
LOW PRES NEAR 11N105W 1007 MB WAS MOVING WSW 15 KT. STRONG 
CONVECTION WITHIN 180 NM W QUADRANT. GOOD OUTFLOW AND GOOD 
CYCLONIC CIRCULATION AT MID LEVELS. POSITION MAY BE MID LEVEL. 
CAN NOT DETERMINE ANY SURFACE CENTER.  
 
...TROPICAL WAVES...
TROPICAL WAVE ALONG 85W MOVING W 10-15 KT. TWO AREAS OF ACTIVE 
CONVECTION WITHIN 2 DEGREES OF WAVE AXIS. CONVECTION PERSISTING 
BUT NOT SHOWING ANY SIGN OF CURVATURE. 

TROPICAL WAVE ALONG 111W FROM 3N TO 15N MOVING W 15 KT. CANNOT 
DETERMINE PRESENCE OF WAVE. LARGE AREA OF CONVECTION AT 10N107W 
HAS PERSISTED PAST SEVERAL HOURS AND IS DOMINATING LOW AND MID 
LEVEL FLOW. 

..ITCZ...
ITCZ AXIS ALONG...7N77W 12N100W 10N112W 7N121W 7N132W 6N140W.
ISOLATED STRONG CONVECTION NEAR 3N78W 8N79W 5N84W AND 8N85W.

MODERATE WITHIN 30 NM OF 7N131W.

...DISCUSSION...

UPPER LEVEL FEATURES...

A WEAKENING UPPER TROUGH ALONG 120W N OF 20N IS CAUGHT BETWEEN 
TWO HIGH CELLS. ONE OVER THE SW US AND THE OTHER CENTERED NEAR 
24N135W. LATER DAY 1 THE TROUGH WILL REMAIN ALONG 120W BUT 
WEAKEN FURTHER. THE TWO HIGH CELLS WILL REMAIN STATIONARY. 

FOR DAY 2 THE WEAK TROUGH REMAINS NEAR 23N117W. THE WESTERN HIGH 
CELL REMAINS NEAR 24N136W RIDGING NE TO THE SECOND CELL 
STATIONARY OVER THE SW U.S.

SURFACE FEATURES...

THE MID PACIFIC HIGH WAS CENTERED NEAR 26N138W AT 1022 MB AND 
WAS PRODUCING NE TRADES OF 20 KT BETWEEN 10N AND 20N W OF 125W. 
WINDS ALONG THE BAJA COAST TONIGHT MOSTLY NWLY 10 TO 15 KT. 
CROSS EQUATORIAL SLY WINDS BETWEEN 110W AND 120W WERE TO 20 KT 
WHILE FURTHER E BETWEEN 4N AND 8N E OF 90W QUIKSCAT SHOWED WLY 
WINDS 20 TO 25 KT.

LATER DAY 1 THE MID PACIFIC HIGH MOVES TO NEAR 28N132W WITH 
LITTLE CHANGE IN WINDS. CROSS EQUATORIAL SLY WINDS WILL REMAIN 
THE SAME. WINDS ALONG THE BAJA COAST WILL REMAIN NWLY 10 TO 15 
KT. SW TO W WINDS TO 20 KT WILL PREVAIL BETWEEN 4N AND 7N E OF 
90W. 

FOR DAY 2 THE PACIFIC HIGH WILL REMAIN STATIONARY NEAR 28N132W 
AT 1023 MB. LITTLE CHANGE TO OVERALL WINDS. POSSIBLE INCREASE IN 
SLY WINDS BETWEEN 100W AND 110W IF LOW PRESSURE DEVELOPS. WINDS 
ALONG THE BAJA COAST REMAIN LIGHT NWLY WHILE WINDS S OF 7N E OF 
95W REMAIN S TO SW TO 20 KT.
