Summary
Northern Kyushu faces a high risk of linear rainbands forming by September 14 morning, potentially causing severe rain-related disasters. Heavy rain, landslides, and flooding are expected across northern to western Japan due to atmospheric instability caused by warm, moist air and a low-pressure system near Hokkaido. Affected areas include Yamaguchi, Fukuoka, and Nagasaki, with warnings in place. Residents are advised to stay indoors during thunderstorms, monitor agricultural facilities, and prepare for hail, lightning, and tornadoes. Linear rainbands, characterized by prolonged heavy rainfall over narrow areas, could exacerbate risks. Vigilance is crucial to mitigate potential disasters.
