REMARKS:
232100Z8 POSITION 16.4N1  153.2E1
TYPHOON YATES (28W) IS MOVING WESTWARD AT APPROXIMATELY
11 KNOTS. IT HAS CONTINUED TO INTENSIFY OVER THE PAST 6
HOURS, BUT NOT AS RAPIDLY AS OVER THE PREVIOUS 6 HOURS.
IT STILL HAS A VERY WELL DEFINED EYE AND IS EASY TO
LOCATE IN ENHANCED INFRARED IMAGERY. A MONSOON DEPRESSION
TO THE SOUTHWEST OF TY YATES, CURRENTLY THE SUBJECT OF A
TROPICAL CYCLONE FORMATION ALERT (REFER TO WTPN22 PGTW)
IS FORECAST TO INTERACT WITH TY YATES. THE INTERACTION IS
ANTICIPATED TO RESULT IN ACCELERATION OF TY YATES TO THE
WEST ALONG OUR FORECAST TRACK. AS THE TWO SYSTEMS
INTERACT, THEY ARE EXPECTED TO DEVELOP A REVERSE-ORIENTED
MONSOON TROUGH, WHICH SHOULD SLOW THE FORWARD MOTION OF
BOTH SYSTEMS AND RESULT IN TY YATES TURNING TOWARD A MORE
NORTHWARD TRACK BY 72 HOURS. NEXT WARNINGS AT 240300Z9
(DTG 240151Z3), 240900Z5 (DTG 240751Z9), 241500Z2 (DTG
241351Z6) AND 242100Z9 (DTG 241951Z2). MAXIMUM
