Typhoon 24, 25, and 26 and intensifying autumn rain in Japan

Overview

By late September, severe weather patterns continued to impact multiple regions. In Fukuoka Prefecture, the Japan Meteorological Agency issued a ‘linear precipitation zone imminent prediction’ for the Chikugo region. While several Level 4 emergency warnings for landslides and heavy rain were lifted in Kumamoto, Saga, Nagasaki, and Fukuoka, weather instability persisted. In the Kinki region, authorities warned of sudden thunderstorms and potential tornadoes through September 28 due to a stationary autumn rain front.

New disruptions emerged by September 28 as heavy rainfall hit Hokkaido, where Sapporo received its first-ever Level 4 Heavy Rain Danger Warning. Intense precipitation caused flooding in an underpass at New Chitose Airport and a nursing home parking lot in Toyohira Ward. These conditions led JR to suspend 108 trains, including 39 Rapid Airport services.

On the morning of September 29, a Level 3 heavy rain warning was issued for Echizen City in Fukui Prefecture due to a cold front. Officials warned of rising river levels in the Reihoku region and potential flooding in low-lying areas, while landslide advisories were issued for Fukui City, Sabae City, and Echizen Town.

Scientific analysis regarding Typhoon 25 (Dujuan) indicates that climate change intensified rainfall in the Tokyo metropolitan area by approximately 5% to 15% compared to historical patterns from 1950 to 1987. Researchers from the international consortium Climameter noted that this added rainfall contributed about 6% to the total damage caused by the storm. Professor Tomonori Sato further suggested that extreme rainfall events in Chiba, Fukui, and Kagoshima were made more likely by human-induced climate change. Meanwhile, Typhoon 26 is moving south near the Izu Islands, bringing expected rain and wind to southern Kanto, while Hokkaido faces an anticipated cold snap with potential high-altitude snow.
