Possibility of occurrence of “linear rain zone” in Tokai, also pay attention to Kanto

The Japan Meteorological Agency has announced that a “linear rain belt” will occur in the Tokai region during the daytime on the 13th, and the risk of disasters may increase sharply. This is the first announcement in the Tokai region since we started predicting the occurrence of linear rain zones in advance this year.

Furthermore, Weathernews’ own analysis predicts that there is a risk of a linear rain belt not only in the Tokai region but also in the Kanto region.

When a linear rain belt occurs, heavy rain continues to fall in the same place, increasing the risk of disaster occurrence. Strict vigilance is required for large-scale flooding, flooding of low-lying areas, flooding of rivers and landslides.

Most places in Kanto are past the peak rainfall.

However, on the Pacific side of Chiba and Ibaraki prefectures where the typhoon will pass from now on, it is necessary to pay attention to flooding of roads and flooding of small and medium-sized rivers due to heavy rain until late tonight.

In addition, the analyzed rainfall in 3 hours exceeds 140 mm on Izu Oshima, increasing the risk of landslide disasters. A belt of active rain clouds extending to the south side of Typhoon No. 8 may continue, and in the northern part of the Izu Islands, vigilance is required for gusts and disasters until early tomorrow morning.

In the Tohoku region, where the front is stagnant, there is a possibility of temporary heavy rain in the morning due to the influx of moist air accompanying this typhoon.

Stay alert for leisure activities even after the weather improves

Expected wave height on the 14th (Sun) noon

On the 14th (Sunday), the typhoon will leave, and the weather will improve in Kanto, etc., and there will be many places where the blue sky will spread after the typhoon has passed.

However, the water level of the river does not go down immediately after heavy rain. The swollen river is faster than usual, and the situation is dangerous, so please do not approach it.

High waves are expected to continue in coastal areas. Since it is during the Obon holidays, some people may be planning to go to the mountains or the sea for leisure, but it is important to act with safety first.
