AN UPPER CYCLONE CUT OFF AT 28N142W AND IS EXPECTED TO MOVE 
LITTLE AND BECOMING ABSORBED IN ABOUT 36 HOURS BY A SHORTWAVE 
TROUGH CURRENTLY W OF THE AREA ALONG 152W. AN UPPER ANTICYCLONE 
IS QUASI-STATIONARY NEAR 17N122W. A RIDGE AXIS EXTENDS SW TO 
NEAR 10N133W ENHANCING ITCZ CONVECTION BETWEEN 123W AND 133W. 
THE RESULTANT DEBRIS MOISTURE SPREADS N ALONG THE W PERIPHERY 
OF THE ANTICYCLONE TO NEAR 20N126W. A RIDGE ALSO EXTENDS N
