 Tropical Storm Matsa gradually intensified as it tracked steadily northwestward ; by late on August 1 it strengthened into a severe tropical storm . Outflow and deep convection to the north remained limited , though the storm was able to intensity further to attain typhoon status on August 2 about 780 km ( 480 mi ) south of Okinawa . Intensification slowed , and late on August 3 Matsa reached a peak intensity of 150 km / h ( 90 mph ) while located 495 km ( 308 mi ) east of the southern tip of Taiwan as reported by the JMA ; the JTWC and the National Meteorological Center of China reported the typhoon as strengthening further to attain peak winds of 165 km / h ( 105 mph ) on August 4 . Shortly after passing over the Japanese island of Ishigaki , Matsa began to weaken steadily as it approached the coast of China , and made landfall as a minimal typhoon late on August 5 near Yuhuan in the southern region of Zhejiang Province . It crossed the Gulf of Yueqing and 40 minutes after its first landfall it struck Mainland China near Yueqing . It quickly weakened to a tropical storm , and within hours of moving ashore the JTWC issued its last advisory . Matsa turned to the north , weakening to a tropical depression on August 7 shortly before entering the Yellow Sea . The weakening depression continued northward , and became an extratropical cyclone on August 9 after hitting the Liaodong Peninsula .
