In Aomori and Akita prefectures, where record-breaking heavy rainfall has exceeded the average rainfall for the first month of August due to a stationary front, the rain has intensified again, and there are places where it is raining very heavily.
The front is expected to stay in the vicinity of northern Japan for about a week, and there is a risk that the rain will continue for a long time and the area of the record heavy rain will spread further.
Record heavy rain in Aomori and Akita
According to the Japan Meteorological Agency, warm and moist air is flowing toward the front extending near northern Japan, and rain clouds are developing in northern Tohoku such as Akita Prefecture, and rain is intensifying again.
In the hour until 11:00 am , 60.5mm of rain fell on
Ogashinzan in
Akita Prefecture and 59mm
of rain fell on
Ogata Village .
Record-breaking heavy rains centered in the northern Tohoku region, with the maximum rainfall in 24 hours being 325 mm in
Aomori Prefecture's
Fukaura Town,
▽ Ajigasawa Town ▽ 202.5 mm, and
Akita Prefecture's
▽ Happo Town 202 mm.
Both numbers are the highest in observation history, and in some places they are more than 1.5 times as many as in August of a normal year.
Due to the rain so far, the risk of landslide disasters has increased significantly in Aomori and Akita prefectures, and ``Sediment disaster warning information'' has been announced in some areas. "Flood risk information" has been announced as the danger of flooding is increasing very much in the Iwaki River.
Long-term stagnation of the front may bring record rainfall
This is the outlook for the future.
It is expected to continue to rain in northern Japan, mainly on the Sea of Japan side of the Tohoku region, and there is a risk of extremely heavy rain of 50 mm or more per hour accompanied by thunder until the 11th.
The amount of rain falling in the 24 hours until noon on the 11th
is expected to be ▽
120 mm in northern Tohoku
, ▽ 100 mm in Hokkaido,
▽ 80 mm in southern Tohoku, and ▽ 50 mm in Niigata Prefecture.
Furthermore, in the 24 hours until noon on the 12th,
▽ northern Tohoku and Hokkaido are expected to receive 100 to 150 mm
of rain, and ▽ southern Tohoku and Niigata Prefecture are expected to receive 50 to 100 mm of rain.
The front is expected to stagnate near northern Japan until around the 16th of this month, and even if the rain weakens mainly in the Tohoku region, it is possible that it will strengthen again. It may increase your risk.
The Japan Meteorological Agency continues to remain vigilant against landslides, low-lying land inundation, and river flooding, and calls for caution against severe gusts of wind such as lightning strikes and tornadoes, as well as "hail."
The ground has loosened in northern Tohoku, which has already experienced record-breaking rainfall, and river water levels continue to rise.
People who live in areas where the risk of disasters is predicted, such as near rivers and cliffs, should stay alert even if the rain slows down or stops. .
