Typhoon Rananim, known in the Philippines as Typhoon Karen, was the strongest typhoon to make landfall on the Chinese province of Zhejiang since 1956. It formed on August 6, 2004, intensifying into a tropical storm on August 8. Rananim gradually intensified, initially moving northward before turning to the northwest and attaining typhoon status. After developing a small eye, the typhoon attained peak winds of 150 km/h (90 mph) as it passed between Taiwan and Okinawa. On August 12, Rananim moved ashore in China, and it dissipated three days later. The name Rananim means "hello" in the Chuukese language.
