Heavy rain is falling again in Aomori and Akita prefectures, which had record heavy rain due to the influence of the front and low pressure.

In northern Tohoku, localized torrential rain will fall before noon, and there is a risk that the risk of disasters will increase sharply.

Please stay vigilant against landslides and river floods, and try to spend your time in a safe place as much as possible.

According to the Japan Meteorological Agency, rain clouds that have developed again from last night are pouring into Aomori and Akita prefectures, which have already experienced record heavy rainfall due to the effects of a low pressure front near the Sea of ​​Japan approaching northern Japan. .

▽The rain gauge installed in Mutsu City by Aomori Prefecture recorded 36 mm in an hour until 3:00 a.m.

▽The rain gauge installed by the Ministry of Land, Infrastructure, Transport and Tourism in Kitaakita City, Akita Prefecture recorded 32 mm in an hour until 4:00 a.m. We observed heavy rain.

It is 1.5 to 2 times more than the normal year in August and 1 month in various places,

such as 306 mm .

In Aomori and Akita prefectures, and in the Oshima region of Hokkaido,

the risk of landslide disasters has increased significantly due to the rain so far, and there are areas where "landslide warning information" has been announced.

Low pressure approaching and heavy rain until noon

This is the outlook for the future.

As a low pressure system on the front passes over northern Japan, intermittent rain is expected in Tohoku and Hokkaido until noon on the 12th.

Especially in northern Tohoku, extremely heavy rain of 50 mm or more per hour is expected, accompanied by thunder.

In addition, the front is expected to remain stagnant near northern Japan for about a week, and although activity is expected to weaken temporarily around the 14th, it is expected to become active again from around the 15th.

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."

It is already raining heavily in various places, and even a little rain can cause disasters, and if

the rain gets stronger, the risk of disasters will increase sharply.

Stay away from dangerous areas such as cliffs and spend your time in a safer place.

Tropical cyclone develops into a typhoon Is it approaching eastern Japan on the 13th?

On the other hand, according to observations by the Japan Meteorological Agency, at 3:00 am on the 12th, a tropical cyclone turned into Typhoon No. 8 over the seas south of Japan.

The central pressure is 1004 hectopascals, the maximum wind speed is 18 meters, and the

maximum instantaneous wind speed is 25 meters.

The typhoon is moving north at a slow speed and is expected to approach eastern Japan on the 13th.

In eastern Japan, the wind is expected to gradually increase from the afternoon of the 12th, and the waves are expected to rise, and on the 13th, there is a possibility of heavy rain, especially on the Pacific side.

The Japan Meteorological Agency is calling for caution against landslides, flooding of low-lying land, sudden rises in rivers, and high waves through the 13th.

Since it overlaps with the Obon season, please check the latest information.

Aomori We need to be vigilant against ``long-term accumulation-type'' disasters

In Aomori Prefecture, not only the towns of Fukaura and Ajigasawa on the Sea of ​​Japan side, which suffered from flood damage, but also the center of Aomori City and the Pacific Ocean side of the prefecture have experienced record heavy rainfall.

It is necessary to be vigilant against the so-called "long rain accumulation type" disasters caused by long-lasting rain in various places.

Aomori 1.5 to 2 times the monthly rainfall in just three and a half days

Due to the stagnant front, the Tsugaru region of Aomori Prefecture experienced record-breaking rainfall three days ago on August 9, causing flood damage in Fukaura Town and Ajigasawa Town.

From the start of the rain on August 8th to 2:00 on the 12th, the amount of rain fell

was 391 mm in Fukaura Town

and 308 mm in Ajigasawa Town. increase.

On the other hand, in Aomori Prefecture, rain continues to fall outside of these areas, such as in the center of Aomori City and on the Pacific Ocean side, resulting in record heavy rainfall.

As of 2:30 a.m., the largest amount of rainfall in a 72-hour period is the highest in observational history,

. It has rained more than a month to two months.

It is difficult to have a sense of danger.

In these areas, there is a possibility that the sudden intensification of rain may not be felt due to heavy rain, but the ground will loosen and even a little rain may cause a disaster.

Such disasters are also called "long rainfall accumulation type" disasters, which are caused by prolonged rain without sudden intensification of rain.

The debris flow that occurred in Atami City, Shizuoka Prefecture in July last year led to a major disaster due to the effects of not-so-strong rain that continued for a long time.

In this disaster, heavy rain of 30 mm or more per hour was not observed, and it continued to rain for several days. did.

In Kure City, Hiroshima Prefecture, where a series of landslides occurred due to the torrential rains in western Japan in 2018, it continued to rain around 10 mm, and sometimes extremely heavy rain of 50 mm or more fell, but most of it was rain that I usually experience. did.

Residents also say, "It was difficult to have a sense of crisis."

Even if the rains abate, be on your guard against 'long rain accumulation' hazards due to long rains.

Check the degree of danger in situations where disasters are likely to occur

In order to protect yourself from disasters, pay attention to evacuation information from local governments, and refer to ``Landslide warning information'' and ``Inundation risk information'' announced when the risk of a disaster increases.

In addition, you can check the risk of landslides, river floods, and inundation on the website of the Japan Meteorological Agency.

Please check the latest information and the situation around you, and try to evacuate early.
