Japan weather alert: Typhoon 17 forms as Chiba faces Level 5 rain warning

Typhoon 17 Typhoon 15 heavy rain warning Japan weather natural disaster

Japan is facing severe weather conditions as Typhoon 15 transitions into a tropical depression and Typhoon 17, known as Nangka, forms near the Ogasawara Islands. Typhoon 15 moved in a reverse direction from east to west, which brought continued heavy rain and sudden thunderstorms to the Kanto and Kansai regions due to moist southern winds.

In Chiba Prefecture, a Level 5 heavy rain special warning has been issued for multiple municipalities, including Chiba City, Ichikawa, and Funabashi, following the occurrence of linear precipitation zones and record-breaking short-term rainfall. Authorities have warned of potential flooding and landslides, urging immediate evacuation.

Meanwhile, Typhoon 17 is currently moving east-northeast at 25 kilometers per hour with a central pressure of 994 hectopascals. While its exact path remains uncertain, meteorologists warn it could approach the Honshu region early next week. A significant concern for coastal areas is the high-energy swells generated by the storm, which pose a threat even under clear skies.

Additional heavy rain warnings and landslide alerts remain in effect for parts of Tochigi, Osaka, and the Kinki region.
