Japan’s Meteorological Agency (JMA) issued an “Imminent Linear Rainband Prediction” for northern Saga Prefecture, indicating a high probability of a linear rainband forming within the next three hours. This weather phenomenon, characterized by a chain of developed cumulonimbus clouds, brings extremely heavy rainfall and a rapidly increasing risk of landslides and flooding. The JMA warns that these conditions pose a severe threat to life. Residents in areas near cliffs and rivers are urged to monitor evacuation information issued by local authorities and assess the surrounding environment. The alert was released at 10:19 PM local time as intense rainfall was already occurring in the region. Authorities are emphasizing the immediate need for caution and preparedness.
