Due to the influence of fronts and low pressure systems, atmospheric conditions have become unstable in western and eastern Japan, and it is raining extremely heavily in the Chugoku region.
Be very careful of sediment-related disasters and river floods, and be careful of gusts such as lightning strikes and tornadoes.
According to the Japan Meteorological Agency, the atmospheric conditions are unstable over a wide area of western and eastern Japan due to the warm and moist air flowing from the south toward the front with a low pressure system extending near Honshu.
During this time, rain clouds develop especially in the Chugoku region, and in Kano, Shunan City, Yamaguchi Prefecture, it is 55.5 mm in one hour until after 0:40 am, and in Koda, Akitakata City, Hiroshima Prefecture, it is one hour until 1:00 am. It rained very heavily on all 52 mm.
Due to the rain that has fallen so far, the risk of sediment-related disasters has become extremely high in Yamaguchi and Hiroshima prefectures, and there are areas where "sediment-related disaster warning information" has been announced. There are rivers that exceed the "dangerous water level".
The front is stagnant on the south coast of Honshu, and atmospheric instability is expected to continue in western and eastern Japan, with heavy rainfall of 30 mm or more per hour, which may cause extremely heavy rainfall locally. ..
The Japan Meteorological Agency warns against sediment-related disasters and river floods, warns against inundation of low land, and calls for careful attention to severe gusts such as lightning strikes and tornadoes.
If there are signs that a developed cumulonimbus cloud is approaching, such as a sudden cold wind, move to a sturdy building to ensure safety.
