Typhoon No. 4 is in the East China Sea at 15:00 on the 4th (Monday) and is moving north-northeast at a speed of about 20 km per hour.

The typhoon may move northward in the East China Sea on the 4th (Monday), gradually change its course from the east, and approach Kyushu on the 5th (Tuesday) and land. After that, it will proceed east on the Pacific side of western Japan and eastern Japan, and is expected to change to an extratropical cyclone on the morning of Wednesday, 6th. It is expected that a typhoon will change to an extratropical cyclone, but it is expected to bring in a large amount of moist air from the tropics, which is the source of rain clouds, and bring heavy rain.

Rainfall may increase further from Kyushu to Tokai 

As the typhoon moves northward, moist air around the typhoon flows in, and heavy rain has already fallen mainly on the Pacific side of western Japan, and there are places where the risk of sediment-related disasters has become extremely high.

From Kyushu to Tokai, it will rain very heavily over the 6th (Wednesday), and the amount of rainfall will increase further.

The expected 24-hour rainfall by 18:00 on the 5th (Tuesday) is in high places.

Shikoku region: 250 mm

Kinki region: 200 mm

Southern Kyushu: 180 mm

Northern Kyushu, Tokai: 150 mm

Amami region: 80 mm

After that, the expected 24-hour rainfall by 18:00 on the 6th (Wednesday) is in a large place.

Kinki region, Tokai region: 200-300 mm

Shikoku region: 100-200 mm

Be wary of sediment-related disasters, and be wary of low land inundation, river flooding and flooding. Also, be careful of severe gusts such as lightning strikes and tornadoes.

From eastern Japan to northern Japan, warm and moist air that surrounds the edge of the Pacific High is flowing in, and cold air below freezing point of 6 degrees Celsius is flowing in the vicinity of 6000 meters above the sky. Atmospheric conditions will be very unstable over the 5th (Tuesday). It is likely that there will be heavy rains due to extremely heavy rain accompanied by lightning. Also, on the 6th (Wednesday), a low pressure system that changes from typhoon No. 4 will approach Kanto, and there is a risk that rainfall will increase further.

The expected rainfall for 24 hours until 18:00 on the 5th (Tuesday) is high.

Hokkaido region, Tohoku region, Kanto Koshin region: 80 mm

Hokuriku region: 60 mm

After that, the expected rainfall for 24 hours until 18:00 on the 6th (Wednesday) is high.

Kanto Koshin region: 100-150 mm

Hokuriku region: 50-100 mm

It is necessary to be vigilant against sediment-related disasters, and to be vigilant against inundation of low land, flooding and flooding of rivers.
