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

BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1500 UTC.

..ITCZ...
AXIS OF INTERTROPICAL CONVERGENCE ZONE 3N78W 7N110W 6N140W.

CYCLONIC CIRCULATION IS CENTERED NEAR 30N118W AND IS EMBEDDED
WITHIN A LONGWAVE TROUGH THAT EXTENDS FROM THE SW U.S. TO
21N135W AND COVERS THE AREA NORTH OF 18N EXCEPT FOR RIDGING
NORTH OF 25N W OF 135W.  MODERATE TO STRONG SUBSIDENCE...DRY AIR
ALOFT...COVERS THE AREA N OF 20N W OF 110W. SATELLITE DERIVED
