IS EMBEDDED IN A LARGER TROUGH THAT COVERS THE AREA NORTH OF A 
LINE 32N110W TO 30N108W TO 23N115W TO 20N120W TO 21N135W TO 
17N140W. ANOTHER CYCLONIC CIRCULATION IS EMBEDDED IN THE WESTERN 
PART OF THE TROUGH WITH A CENTER NEAR 20.5N139W. BOTH CENTERS 
ARE MOVING EAST BUT THE OVERALL TROUGH WILL REMAIN IN PLACE 
THROUGH 48 HOURS. THE AREA IS DRY AND CLOUD FREE IN THE MIDDLE 
AND UPPER LEVELS. BROKEN TO OVERCAST STRATOCUMULUS IS IN THE 
LOWER LEVELS.

REMAINDER OF THE AREA IS UNDER BROAD ANTICYCLONIC FLOW. THIS 
AREA IS WEAKLY DIFFLUENT IN THE UPPER LEVELS WITH WIDESPREAD 
AREAS OF MULTIPLE LAYERED CLOUDS. 

THE HIGH CLOUDS IN THE AREA NORTH OF THE ITCZ TO 16N FROM 120W
