Due to the effects of low pressure and fronts, the atmosphere in Tohoku and Hokkaido may become unstable over the 15th, resulting in intermittent heavy rain. It is necessary to pay sufficient attention to sediment disasters and river flooding.
According to the Japan Meteorological Agency, a cyclone with a front is expected to travel northeast along the Sea of Japan and pass through Tohoku and Hokkaido over the 15th.
As a result, the atmospheric conditions become unstable, especially in Tohoku and Hokkaido, and especially on the Sea of Japan side, heavy rain of 30 mm or more per hour may accompany thunder over 15 days.
The amount of rainfall in the 24 hours until the evening of the 15th is expected to be 120 mm in Tohoku and 100 mm in Hokkaido, where there is a lot of rainfall.
The Meteorological Agency calls for careful attention to sediment-related disasters, inundation of low-lying land, flooding of rivers, and heavy gusts such as lightning strikes and tornados, and "hail."
