July 17, 2023 at 17:38
From the 18th to the 20th, heavy rain will fall once more, mainly in the Tohoku region, and there is a risk of heavy rain once more. Even in Akita Prefecture, which had a record heavy rain last weekend, the rain is expected to intensify once more. Watch out for landslides, flooding of low-lying land, rising rivers and flooding.
Seasonal rain front moves to Tohoku region, fear of heavy rain once more
Akita Prefecture was hit by record heavy rain last weekend.
On the 17th, although the rain was weak, it rained in some places and the amount of rain increased. The total amount of rain since the beginning of the fall has already exceeded 400 mm, which is a record heavy rainfall.
[Precipitation amount from the beginning of the rain (12:00 on the 14th) to 16:00 on the 17th (preliminary figures by AMeDAS)]
Nibetsu, Akita City 434.0mm
Fujisato 346.0mm
Kakunodate 342.5mm
Sannai Iwami, Akita City 325.5 mm
Semboku City Tazawako Highlands 290.0mm
Akita 259.0 mm
And following the 18th, there is a risk of warning-level heavy rain once more, mainly in the Tohoku region.
The cause of heavy rain is the rainy season front. This seasonal rain front is expected to extend to the Tohoku region on the 18th and move southward around Honshu around the 20th. Since “warm and moist air” that causes heavy rain flows toward the seasonal rain front, the front is likely to become more active.
What is the expected rainfall?
The expected rainfall for 24 hours until 18:00 on the 18th is
Tohoku region 80 mm
The expected rainfall for 24 hours until 18:00 on the 19th is
Tohoku region 50 to 100 mm
The expected rainfall for 24 hours until 18:00 on the 20th is
Tohoku region 50 to 100 mm
is expected.
In particular, Akita Prefecture continues to face a high risk of landslide disasters due to heavy rains. Also, some rivers are rising. In the Tohoku region, be alert for landslides, flooding of low-lying land, rising water levels and flooding of rivers.
The Tohoku region is not the only region where there is a risk of heavy rain.
In the Hokuriku region, there is a risk of warning-level heavy rain from the 19th to the 20th as the front moves southward. Again, check the latest weather information and stay away from slopes and rivers.
What are the harbingers of landslide disasters?
When a landslide disaster occurs due to heavy rain, there is a phenomenon that serves as a precursor. Please keep this in mind in case of emergency.
The first is that cracks can form in cliffs and ground.
The second is hearing the crackling of wood, the clashing of stones, and the smell of earth.
The third is that the water in wells, rivers, and springs becomes turbid. Even if the spring water stops, it is one of the harbingers.
The fourth is that water springs out from cliffs and slopes.
In addition, there are pebbles falling apart, rumbling of the ground and rumbling of the mountains, the water level of rivers dropping even though it continues to rain, and trees tilting. At times like this, the risk of landslide disasters is increasing. Call out to people around you immediately and evacuate to a safe place.
