The initial system that led to Typhoon Doris began between Pohnpei and Chuuk State on July 9.[2] Tracking towards the west-northwest, it passed near Chuuk and became a tropical depression on July 11 while 480 km (300 mi) south of Guam.[1][2][3]Template:Rp Doris became a tropical storm by 12:00 UTC that day as it began to track northwest across the Philippine Sea. Early on July 13, Doris strengthened into a typhoon while approximately 800 km (500 mi) east of Luzon.[1][3]Template:Rp The next day, Doris attained one-minute sustained winds of 150 km/h (90 mph). It weakened as it curved north towards the southern Ryukyu Islands, becoming a tropical storm on July 14 and then a tropical depression on July 15 while passing near Tarama, Okinawa. The system continued to decay as it moved north and dissipated over the Yellow Sea on July 17.[1]
