Typhoon Chan-hom, known in the Philippines as Typhoon Falcon, was a large, powerful and long-lived tropical cyclone that affected most countries in the western Pacific basin. The ninth named storm of the 2015 Pacific typhoon season, Chan-hom developed on June 29 from a westerly wind burst that also spawned Tropical Cyclone Raquel in the southern hemisphere. Chan-hom slowly developed while moving to the northwest, aided by warm waters but disrupted by wind shear. The storm meandered near the Northern Marianas Islands, passing over the island of Rota before beginning a steady northwest track. While near the island, the storm dropped heavy rainfall on neighboring Guam, causing flooding and minor power outages. Chan-hom intensified into a typhoon on July 7, and two days later passed between the Japanese islands of Okinawa and Miyako-jima. There, strong winds left 42,000 people without power, while 27 people were injured. Around that time, the storm caused a surge in the monsoon trough, in conjunction with Tropical Storm Linfa, which caused flooding and killed 16 people in the Philippines.
After passing by Okinawa, the typhoon reached peak winds of 165 km/h (103 mph), according to the Japan Meteorological Agency. It passed north of Taiwan, where it brought beneficial rainfall that replenished reservoirs. On July 11, Chan-hom became the strongest typhoon to make landfall in the Chinese province of Zhejiang in the month of July. About 1.1 million people were evacuated ahead of the storm, and across the country, the storm left ¥9.84 billion (US$1.58 billion) in damage, as well as one death. Later, the storm turned to the northeast toward the Korean Peninsula. Jeju Island offshore South Korea recorded 1,250 mm (49 in) of rainfall, and one person died due to a thunderstorm in the country. On July 12, the storm struck the Ongjin peninsula in North Korea, and became an extratropical cyclone shortly thereafter. The remnants later caused flooding and power outages in the Russian Far East.
