^RECENT ANIMATED MULTISPECTRAL IMAGERY INDICATES CON-
VECTION IS STILL IN THE PROCESS OF CONSOLIDATING OVER
THE LOW LEVEL CIRCULATION CENTER (LLCC). TS YUTU IS
TRACKING WESTWARD SOUTH OF THE SUBTROPICAL RIDGE
(STR) AXIS ANCHORED NORTH OF MICRONESIA. THE STR WILL
REMAIN THE PRIMARY STEERING INFLUENCE UNTIL A DEEPENING
TROUGH OVER WESTERN JAPAN BREAKS DOWN THE RIDGE AFTER 48
HOURS, INDUCING A MORE POLEWARD TURN. THE AVAILABLE DYNA-
MIC AIDS ARE IN CLOSE AGREEMENT WITH THIS SCENARIO, AND
PREDICT TS YUTU WILL REACH THE RIDGE AXIS NEAR 72 HRS.
IN THE SHORT TERM, THE TC WILL FOLLOW A MORE WESTWARD
TRACK THAN DEPICTED BY THE MODEL GUIDANCE, SINCE UPPER
AIR OBSERVATIONS AT YAP AND GUAM STILL INDICATE A EAS-
TERLY STEERING CURRENT..
