More than 1,600 flights have been cancelled and about 500,000 people have been evacuated, as Typhoon Dolphin is set to make landfall on China’s eastern coast overnight on Sunday. The country’s National Meteorological Center (NMC) issued a red typhoon alert, its severest warning, on Sunday morning. Authorities are preparing for floods and landslides, as the typhoon is set to bring intense rain and powerful winds to the densely populated eastern coastal regions. Dolphin swept through Japan’s southern Okinawa prefecture over the weekend, injuring seven people and cutting power to more than 50,000 buildings. The typhoon cut off the electricity for 5,290 households in Okinawa by Sunday afternoon, Okinawa Electric Power Company reported.
