A Level 4 Urgent Warning for landslides has been issued for parts of the prefecture.

The large and powerful typhoon is expected to move northward, bringing fierce winds and rough seas to the Sakishima Islands. Bands of heavy rain clouds could form through early morning, and the risk of disasters could rise sharply.
