Aomori and Akita prefectures, which have experienced record-breaking rainfall, have already suffered damage such as flooding, but by the 12th, there is a risk that heavy rain will fall again in northern Tohoku.
Even in areas where the rain has weakened once, the risk of disasters may rise sharply, so please continue to be extremely vigilant against landslides and river floods.
According to the Japan Meteorological Agency, warm, moist air continues to flow toward a stationary front near northern Japan, bringing record heavy rainfall to northern Tohoku.
In Aomori
and Akita prefectures, it rained intermittently on the
11th
. , ▼
In Happo Town,
Akita Prefecture, it is 261 mm

Rain clouds developed locally in the northern part of Tohoku at this time as well, and during the hour until 5:00 p.m., a rain gauge installed by Aomori Prefecture in Sotogahama Town recorded 32 mm of heavy rain.
In Aomori and Iwate prefectures, due to the heavy rains, the risk of landslide disasters has increased significantly, and there are areas where "landslide warning information" has been announced.
Rain is expected to intensify again from the night of the 11th to the 12th due to the approach of a low pressure system
This is the outlook for the future.
As a low pressure system on the front passes through northern Japan, rain is expected to intensify again in Tohoku and Hokkaido from the night of the 11th to the 12th.
Especially in northern Tohoku, there is a risk of extremely heavy rain of 50 mm or more per hour accompanied by thunder, and localized torrential rain of 80 mm or more per hour.
The amount of rain falling in the 24 hours until the evening of the 12th
is expected to be ▽
200 mm in northern Tohoku and ▽ 120 mm in southern Tohoku and Hokkaido.
Furthermore, in the 24 hours until the evening of the 13th,
▽ North Tohoku is expected to have 100 to 150 mm, and
▽ South Tohoku is expected to have 50 to 100 mm
.
Heavy rains have already hit many places, so the risk of landslides and flooding could increase in a short amount of time.
In addition, the front is expected to stagnate near northern Japan for about a week, and although activity is expected to weaken temporarily around the 14th of this month, 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."
Stay alert when the rain eases or stops and stay away from dangerous areas such as rivers and cliffs.
Tropical cyclone is expected to develop into a typhoon Is it approaching eastern Japan on the 13th?
Meanwhile, a tropical depression moving northward over the sea south of Japan is expected to develop into a typhoon within the next 24 hours.
After that, it will continue to move north while developing, and is expected to approach eastern Japan on the 13th.
In eastern Japan, the winds will gradually increase from the 12th and the waves will rise, and on the 13th there is a possibility of heavy rain, especially on the Pacific side.
The Japan Meteorological Agency is calling on eastern Japan to pay close attention to 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.
Japan Meteorological Agency "Possibility of heavy rain from 15th to 16th in northern Japan"
Hiroyuki Morinaga, Director of the Japan Meteorological Agency's Weather Consultation Center, commented on the outlook for heavy rains associated with the stagnation of the front, saying, "From the night of the 11th to the 12th, heavy rain accompanied by thunder and very heavy rain will fall in northern Japan, and the Sea of Japan in the Tohoku region will fall. There is a possibility that the area of record-breaking heavy rain will expand, mainly in the northern part of the prefecture.Since it is already raining heavily, there are areas where the risk of landslides and other disasters will increase even with a little rain in the future."
Regarding linear rainfall belts, which have developed rain clouds one after another, he said, "At present, there is no forecast that the possibility is high, but if it increases, I would like to inform you as soon as possible."
In addition, although the activity of the front will temporarily weaken around the 14th of this month, the front will reappear due to the cold weather in the sky, etc., and there is a risk of heavy rain in northern Japan from the 15th to the 16th of this month. .
“Be extra careful when going out during Obon.”
On the other hand, regarding the tropical cyclone in the south of Japan, "There is a risk that it will develop into a typhoon and approach the Pacific Ocean side of eastern Japan in the future. Although it is small as a typhoon, it will rapidly develop due to the effects of low pressure and cold air above. It may develop, so please pay attention to the latest information."
Also, since the approach coincides with the Obon season, there is a possibility of localized heavy rain or very heavy rain depending on the location. Please check the weather conditions at your destination and on the way, and act with plenty of time."
