Due to the effects of the rapidly developing low pressure system, very strong winds will blow from northern Japan to the coastal areas of western Japan after the evening of the 28th, and heavy snow may occur mainly on the Sea of ​​Japan side after the 29th.

In addition to the traffic effects of blizzards, you need to be alert to blizzards, heavy snow, and high waves.

According to the Japan Meteorological Agency, from the 28th to the 29th, a low pressure system in the Sea of ​​Japan is expected to pass through northern Japan while rapidly developing, and then a strong winter-type pressure system will be established.

Very strong winds along the coast

With the approach of a low pressure system, the wind will intensify mainly in the coastal area on the Sea of ​​Japan side, and there is a risk that extremely strong winds will blow in western Japan after the evening of the 28th, in eastern Japan after the night of the 28th, and in northern Japan after the 29th.



The maximum wind speed expected over the 29th is


▽ 25 meters in Hokkaido and Chugoku region,


▽ 23 meters in Tohoku and Kinki, and Hokuriku,


▽ 20 meters in northern Kyushu, and the


maximum instantaneous wind speed is expected to reach 30 to 35 meters. ..



The wind will be stronger on the 30th, and the maximum instantaneous wind speed is

expected to reach 35


to 45 meters in Hokkaido


and 25 to 35 meters in Tohoku and Hokuriku.



The waves are high, and on the Sea of ​​Japan side of the Chugoku region from Hokkaido, a large injury of over 6 meters is expected over the 29th.

Be wary of heavy snow after the 29th

From the 28th to the 29th, the winter-type pressure distribution will become stronger, so it is necessary to be cautious about heavy snowfall, especially on the Sea of ​​Japan side of the Chugoku region from Hokkaido.



The amount of snow that falls in the 24 hours until the morning of the 29th

is expected to be


30 cm in Hokkaido


, 25 cm in Hokuriku


, 20 cm in Tohoku,


and 15 cm in Niigata Prefecture.



After that, in the 24 hours from the morning of the 29th to the morning of the 30th, there are many places


▽ 70 cm to 90 cm in Niigata prefecture,


▽ 60 cm to 80 cm in Hokuriku and Gifu prefecture,


▽ 50 cm to 70 cm in Tohoku,


▽ It

is expected that it will snow 40

to 60 centimeters in Kinki,


30 to 50 centimeters in Hokkaido,


and 20 to 40 centimeters in the Chinese region.

Be wary of blizzards, heavy snow, and high waves

The Japan Meteorological Agency is wary of traffic effects from uncertain blizzards and snowdrifts, storms, heavy snow, and high waves, and is calling for careful attention to snow accretion on electric wires and trees in addition to avalanches.
