...DISCUSSION...
LARGE ANTICYCLONE CENTERED NEAR 31N1328W IS PRODUCING BROAD 
ANTICYCLONIC FLOW THAT COVERS THE AREA N OF 24N W OF 125W. WATER 
VAPOR SATELLITE IMAGERY INDICATES STRONG SUBSIDENCE AND STABLE 
CONDITIONS N OF 25N AND FROM 10N-25N W OF 120W. AN UPPER LEVEL 
TROUGH IS FROM 24N127W TO CYCLONIC CIRCULATION NEAR 11N132W.
