What is heavy rain?
Heavy rain refers to rainfall of 30 mm or more and less than 50 mm per hour. This is an image of falling like an upside down bucket. In addition, even with an umbrella, regarding half of the people sleeping inside a wooden house notice the rain. Outside, the road becomes like a river, and cars running on the highway may experience “hydroplaning,” a phenomenon in which a film of water forms between the tires and the road surface, making the brakes inoperable.
In places where heavy rain is expected, it is possible to cause landslide disasters, flooding of low-lying land, and swelling and flooding of rivers, so caution is required.
