RADAR IMAGERY INDICATES THE SYSTEM HAS INCREASED SPEED OVER THE PAST 
SIX HOURS, MAKING LANDFALL OVER THE YUHUAN PENINSULA AT 272330Z. TS 
17W IS FORECAST TO CONTINUE TO TRACK WESTWARD INTO CENTRAL CHINA UNDER

THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM
WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MINIMUM CENTRAL
