At 3:48 p.m., the Japan Meteorological Agency announced a meteorological disaster prevention bulletin for the ``linear precipitation band last minute forecast,'' stating that the possibility of a linear precipitation band forming in the southern part of Nagasaki Prefecture within the next three hours is increasing. A "linear precipitation belt" is a phenomenon in which a series of developed cumulonimbus clouds bring heavy rain, and extremely heavy rain continues to fall in the southern part of Nagasaki Prefecture, potentially rapidly increasing the risk of life-threatening landslides and floods. The Japan Meteorological Agency urges people who are near cliffs or rivers to check evacuation information from local governments and check the surrounding situation.
