In Aomori and Akita prefectures, which have experienced record heavy rainfall due to stagnant fronts, intermittent and extremely heavy rainfall has increased the risk of river flooding and landslide disasters. There are areas where


The front is expected to stay near northern Japan for about a week, and there is a possibility that the rain will continue for a long time and the area of ​​record-breaking rainfall will expand 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.



In Imabetsu Town, Aomori Prefecture, 50mm of rain fell in an hour until 5pm.



It has been a record heavy rain mainly in the northern part of Tohoku, and the amount of rainfall from the beginning of the 8th to 4:00 pm on the 10th

was 354.5 mm in ▽ Fukaura Town in


Aomori Prefecture, ▽

236.5 mm in Ajigasawa Town, and ▽

▽ In Happo-cho, it is 232 mm,

which

is more than one month in August in a normal year, and in Fukaura-cho, Aomori Prefecture, it is more than double.

The Mitane River, a class 2 river that flows through Mitane Town, Akita Prefecture, flooded near Kamiiwagawa Ochiai in Mitane Town before 2:00 pm. But we are calling for you to take actions that are likely to save your life in a safe place.

In addition, the Iwaki River, which is a Class 1 river that flows through Aomori Prefecture, continues to have high water levels. Some regions have been announced.










Long-term stagnation of the front may bring record rainfall

This is the outlook for the future.



It is expected to continue raining 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 12th.



The amount of rain falling in the 24 hours until the evening of the 11th

is expected to be


120 mm in northern Tohoku


, 100 mm in Hokkaido, and 80 mm in southern Tohoku.

Furthermore, in the 24 hours until the evening of the 12th,

100 to 200 mm

of rain is expected in northern Tohoku, and 100 to 150 mm in southern Tohoku and Hokkaido.

The activity on the front is expected to weaken temporarily around the 14th of this month, but it is expected to become active again after that and stay stagnant near northern Japan for the next week or so.

The rain could weaken and then pick up again, and it could continue for a long time to extend the area of ​​record-breaking rainfall.

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."

Stay away from dangerous areas, such as near rivers and cliffs, and stay safe even when the rain subsides or stops.














Even a little rain can quickly increase disaster risk

In Aomori and Akita prefectures, which have experienced record-breaking rainfall, it is important not to let your guard down even if the rain is temporarily weakening.



The ground has been loosened by the rain so far, and the rivers are rising. From now on, even a little rain will increase the risk of disasters, and the dangerous situation will continue.



If you sense danger without lowering your vigilance, ensure safety as soon as possible.

A tropical cyclone may approach eastern Japan on the 12th and 13th

On the other hand, a tropical depression moving northwest south of Japan is expected to develop into a typhoon within the next 24 hours.



After that, it will continue to move north while intensifying, and may approach eastern Japan from the night of Friday the 12th to Saturday the 13th.



In eastern Japan, the wind will gradually increase from the 12th and there is a possibility of heavy rain, so please pay close attention to future information.

The rain might get stronger again

Due to the effects of a stationary front near northern Japan, Aomori and Akita prefectures experienced record-breaking heavy rains that greatly exceeded the amount of rain for one month in August in a normal year. reported.



In addition, the water level continues to be high in the Iwaki River, which is a class A river that flows through the western part of Aomori Prefecture.



The front that brought torrential rain in Aomori Prefecture on the 9th moved slightly southward, and during the daytime on the 10th, rain clouds developed over Akita and Iwate prefectures.



Although the area where active rain clouds flow in is moving north-south, it will continue to cover the northern Tohoku area, and the rain is expected to continue to fall over the next week, alternating between stronger and weaker.

Don't let your guard down even if the rain weakens!

Even in areas where the rain has stopped or weakened, we must be vigilant as rain clouds may develop again.



When there is a lot of rain, the rainfall that accumulates in the soil cannot be removed immediately, and the ground becomes loose for several days to a week. .



In addition, even if the rain in the downstream area weakens, the rain that falls in the upstream and tributary areas flows with a time difference, so the water level may rise and the risk of flooding may suddenly increase.



During the torrential rains in western Japan in 2018, as the weather improved and restoration work progressed, a mudslide occurred upstream of the Enoki River, which flows through Fuchu Town, Hiroshima Prefecture, and sediment flowed into houses.

Beware of the "Long Rain Accumulation Type", which is less dangerous

In the case of the so-called "long rainfall accumulation type" where the total rainfall is increasing even though the rain is not so strong, there are few short-term rains such as "very heavy" or "very heavy" that make you feel dangerous. , the timing of evacuation becomes difficult.



When the rain lasts for a long time like this time, instead of focusing only on the amount of rainfall for a short period of time, we will check the weather conditions and water levels in the surrounding area on the website of the Japan Meteorological Agency, etc., and receive evacuation information from local governments. Even if you haven't, if you sense danger, secure your safety as soon as possible.



In past disasters, there have been a series of cases in which people who have difficulty evacuating on their own, such as the elderly and people with disabilities, have become victims.



In Niigata Prefecture, where heavy rains last week caused major damage to houses, there were cases in which residents' conversations led to early evacuation.



If your elderly family members live far away, calling them will make it easier for them to evacuate.



Even if the rain weakens or stops temporarily, please do not let your guard down and continue to be vigilant while talking to each other in your community and at home.
