Due to the influence of front lines and low pressure, extremely heavy rains fall in the Tokai, and the risk of sediment-related disasters is extremely high in Nagano and Aichi prefectures. Heavy rain falls mainly in eastern Japan on one day, and in Shizuoka and Aichi prefectures, there is a possibility that the rainfall will be record heavy, with one month or more of normal years. We need to be alert for sediment-related disasters, inundation of low-lying land, and floods of rivers.
According to the Japan Meteorological Agency, warm and moist air is flowing toward the front and low pressure, so rain clouds are locally developing in the Tokai and Koshin areas.

Rain continues to fall intermittently, and in Shizuoka and Aichi prefectures, it is possible that it will be a record heavy rainfall, as it will rain for July 1 month of normal year or more in the 24 hours until the evening of the day.
