Typhoon Champi Sweeps East Asia: Impacts on Taiwan, Japan and the Korean Peninsula
By Drooid · · How we work
Storm Overview
Typhoon Champi, the season’s 30th tropical cyclone, intensified to super-typhoon strength before moving westward toward Taiwan and then curving northeast. Meteorological agencies reported central pressures from 905 to 980 hPa and sustained winds between 40 m s?¹ (144 kph) and 70 m s?¹ (252 kph), with peak gusts of 191 kph near the centre. The system was forecast to become extratropical as it approached the East China Sea and Japan’s main islands.
Regional Forecasts and Path
The Japan Meteorological Agency projected Champi to travel north over the East China Sea, possibly brushing Kyushu before turning extratropical. Taiwan’s Central Weather Administration expected the eye to pass just off the northeastern coast, then head toward the Chinese coast. The Korea Meteorological Administration anticipated the closest approach to the Korean Peninsula around the weekend, with the strongest effects on Jeju Island and southern coasts. All agencies warned of wind radii of roughly 320 km that could produce prolonged strong-wind conditions if the storm stalled.
Impacts and Casualties
- Taiwan: One fatality; injuries reported between 94 and 171. About 1,000 residents were evacuated from mountainous areas. All domestic flights and most international flights were cancelled.
- Japan: Rain totals reached 89.5 mm in Kihoku within one hour and 302 mm in Owase over 12 hours. Power outages affected roughly 8,400 households in Okinawa. Hundreds of flights were cancelled, and gusts up to 162 kph were recorded on Ishigaki Island.
- Korea: Forecast rainfall for Jeju Island ranged from 50 mm to over 150 mm in mountains, with wave heights up to 6 m along the southern coast. Coastal safety watches were issued for three days.
Official Responses
- The CWA issued mobile-phone alerts urging shelter and warned of gusts over 150 kph.
- Lee Ming-chen, head of Suao, said the military stood ready to deploy amphibious vehicles and rescue boats if needed.
- The KMA advised travelers to monitor updates and cautioned that high waves could affect maritime operations.
- Japanese authorities urged caution for heavy rain in northern Kyushu, the Chugoku and Kinki regions, and the Hokuriku central region.
On-the-Ground Reports
In Yilan County, sandbags were distributed and rescue vessels placed on standby. Residents on Jeju reported sudden downpours beginning around midday, with continuous rain through the weekend and gusts of at least 55 kph on land. Coastal communities in Okinawa noted power disruptions and damage from wind-driven debris.
Conflicting Reports & Gaps
- Injury figures: The CWA cited 94 injuries; other reports listed 171. Both agree on a single fatality.
- Rainfall measurements: Japanese observations recorded 302 mm in Owase, while forecasts for the Sakishima Islands projected 200 mm in 24 hours.
- Flight cancellations: Reuters detailed 262 domestic and 669 international cancellations in Taiwan; the BBC described “hundreds of flights” cancelled across the region.
Verbatim Quotes
- “When necessary, the military will come in to help people, including using amphibious vehicles for evacuations or disaster relief,” — Lee Ming-chen, head of the port town of Suao
What’s Next
Meteorological agencies expect Champi to weaken to a Category 1 equivalent as it moves northeast, with the JMA forecasting extratropical transition near the Korea Strait by early the following day. Forecasts differ on whether the storm will pass closer to the Korean Peninsula or head toward Kyushu, but all agree that rain and strong winds will continue to affect Jeju Island, southern Japan and coastal Korea through the weekend. Residents should stay updated with the latest advisories from the JMA, CWA and KMA.
