Atmospheric conditions have become unstable nationwide due to the effects of cold air over the sky, and rain clouds have developed locally.
The Japan Meteorological Agency calls for careful attention to low land inundation, river flooding, and sediment-related disasters.
According to the Japan Meteorological Agency, due to the effects of cold air in the sky and rising daytime temperatures, atmospheric conditions have become unstable nationwide and rain clouds have developed locally.
In the hour until 2:00 pm, it rained 33 mm heavily in Tono City, Iwate Prefecture.
Due to the rain that has fallen so far, as of 2:00 pm, the risk of sediment-related disasters has become extremely high in Iwate, Yamagata, and Fukushima prefectures, and there are areas where "sediment-related disaster warning information" has been announced.
After this, there is a risk of extremely heavy rain of 50 mm per hour, accompanied by local lightning, over a wide area including Okinawa and Amami, where the Baiu front is stagnant.
The Japan Meteorological Agency calls for careful attention to low land inundation, river flooding, landslides, gusts such as lightning strikes and tornadoes, and "hail".
If there are signs that a developed cumulonimbus cloud is approaching, such as a sudden cold wind, move to a sturdy building outdoors, close the curtains indoors, and move away from the windows.
