Due to the rapid development of low pressure systems and the progress toward Hokkaido on the 21st, extremely strong winds are expected to blow from the night of the 20th to the 21st in Hokkaido and Tohoku, and the Japan Meteorological Agency is calling for caution against blizzards.



As the winter-type pressure distribution becomes stronger, it is expected that snow will intensify on the Sea of ​​Japan side including Hokuriku and Niigata prefectures, so it is necessary to be cautious about heavy snowfall.

According to the Japan Meteorological Agency, due to the influence of low pressure systems moving near the Izu Islands, the atmospheric conditions are unstable and it is raining on the Pacific side and the Izu Islands, and there are places where it is snowing in Hokkaido and Tohoku.

The low pressure system is expected to develop rapidly and proceed to the vicinity of Chishima in Hokkaido, and after the night of the 20th, a very strong wind is expected to blow with snow mainly in Hokkaido and Tohoku.



The maximum wind speed expected over the 21st is 25 meters in Hokkaido and Tohoku, and the maximum instantaneous wind speed is expected to reach 35 meters.



On the 21st, the maximum instantaneous wind speed is expected to be 35 meters even on land in Hokkaido, which may cause a blizzard with no visibility, which may affect transportation.

The waves are high, and it is expected to be a big hit in Hokkaido, Tohoku, and Niigata prefecture.



The Japan Meteorological Agency warns against blizzards and snowdrifts as well as storms and high waves.



In Hokkaido, you need to be careful about storm surges.

Be wary of heavy snowfall in winter

Strong cold air also flows into the sky, and the winter-type pressure distribution is strengthened, so it is necessary to be cautious about heavy snowfall.

The amount of snow that falls in the 24 hours until the morning of the 21st is expected to be 70 cm in Niigata prefecture, 60 cm in Hokuriku and Nagano prefectures, and 50 cm in Hokkaido.
