Due to the rapidly developing low pressure system, a very strong wind will blow over a wide area from Hokkaido to Kyushu on the 29th, and it is expected that a blizzard will occur mainly on the Sea of Japan side.
Be wary of traffic impacts, blizzards, and heavy snow.
According to the Japan Meteorological Agency, the low pressure system in the Sea of Japan is rapidly developing and moving eastward, causing strong winds mainly in the coastal areas, and there are also places where very strong winds with a wind speed of 20 meters or more are blowing.
The maximum instantaneous wind speed observed so far is
▽ 30.1 meters at around 4:20 am in Makkari Village, Hokkaido
▽ 26.5 meters after 3:40 am in Nishikan Ward, Niigata City.
On the coast of the Sea of Japan side from Hokkaido to northern Kyushu, there is a risk of extremely strong winds blowing on the 29th, so caution against storms is required over a wide area.
Especially in snowy areas, the so-called "whiteout" can occur, which is a blizzard that is difficult to see due to the snow that is rolled up by the wind.
The waves are high, and it is expected that there will be a large injury of over 6 meters centered on the Sea of Japan side.
In addition, due to the increased winter-type pressure distribution, it is necessary to be cautious about heavy snowfall, especially on the Sea of Japan side from Hokkaido to the Chugoku region.
The Japan Meteorological Agency is wary of blizzards, heavy snow, and high waves, and calls for careful attention to avalanches and power outages caused by snow accretion on electric wires and trees.
Also, in Tohoku and Hokuriku, the atmospheric conditions are expected to become unstable, so it is necessary to be careful about gusts such as lightning strikes and tornadoes.
