Taiwan's Central Weather Administration (CWA) issued a land warning Thursday as Typhoon Champi approached the island. The CWA said gusts near the storm's center remained above 227 km/h (141 mph) despite slight weakening on Thursday. The storm was about 520 km (320 miles) southeast of Taiwan's southern tip, and its radius had widened to about 320 km (199 miles) — enough to cover most of Taiwan.
Forecasters expect Champi to pass closest to Taiwan late Friday, skirting the island's northeastern coast before turning north toward the seas off Shanghai and eventually moving into southern Japan. Taiwan authorities warned of destructive winds, torrential rain and waves exceeding six meters.
Taiwan cancelled 125 flights as the storm approached. China Airlines and Tigerair Taiwan cancelled Thursday's flights to Okinawa, and two domestic carriers dropped some services to outlying islands. It is the second round of disruption from the same storm, which grounded flights at Guam over the weekend.
Japan Airlines, ANA and Skymark cancelled more than 100 flights, mostly domestic, between Thursday and Sunday, disrupting travel for over 11,000 passengers. The typhoon is forecast to pass over Japan's westernmost inhabited island, Yonaguni, in Okinawa Prefecture. JAL said many flights at nine island airports including Naha would be cancelled October 22-24, and ANA cancelled all Miyako and Ishigaki flights for October 23.
The approaching storm is also disrupting the major military exercise called Keen Sword underway around Japanese islands near Taiwan, forcing changes to the US-Japan drill schedule.
China's Central Meteorological Observatory forecast sustained strong winds and heavy rain along the southeast coast. From the night of October 23 through October 26, eastern and northern Fujian, eastern and northern Zhejiang, and Shanghai expect heavy to torrential rain, with local downpours; cumulative rainfall of 90-150 mm in parts of eastern Zhejiang, eastern Fujian and southern Shanghai, with coastal areas locally exceeding 200 mm. Gale-force winds of 6-8 with gusts to 9-10 are expected across most of the East China Sea, Taiwan Strait, waters east of Taiwan and the Bashi Channel, rising to 10-12 near Taiwan.
Champi was at one point a super typhoon and one of the strongest storms in the Pacific this year. Strong winds from Champi, with gusts up to 120 mph, are expected to affect Taiwan and eastern China from Thursday night into Sunday, potentially causing structural damage, prolonged power outages and transportation delays. The Joint Typhoon Warning Center's latest update put Champi's maximum sustained winds at nearly 195 km/h.
Champi is a separate storm from the recent Typhoon Chanthu, with a different track and impact area. Champi is expected to pass off northeastern Taiwan, turn north toward the Chinese coast and move into southern Japan.
China's meteorological agency said Champi's later path and impacts are expected to become clearer on October 22. Taiwan has placed emergency services on standby. The storm is projected to turn northeast around October 24 and gradually weaken, but Taiwan and eastern China still face heavy rain, strong winds and high seas before then.
