In Kanto Koshin, heavy snow is expected to occur over a wide area including the plains from the evening of the 23rd to the Sunday of the 24th, and there is a risk that it will accumulate even in central Tokyo.
It is necessary to pay sufficient attention to the impact on traffic and freezing of the road surface.
According to the Japan Meteorological Agency, it is raining over a wide area of western and eastern Japan due to the influence of the stagnant front on the south coast of Honshu.
From now on, as the low pressure system on the front line develops and the cold air flows eastward, it is expected that rain will turn into snow mainly along the mountains in Nagano, Yamanashi, and Kanto.
From the evening of the 23rd to the 24th, heavy snowfall will occur over a wide area including the plains of the Kanto region, and there is a risk that it will accumulate even in central Tokyo.
The amount of snow that falls in 24 hours until the morning of the 24th is large,
▽ Nagano prefecture and Yamanashi prefecture, along the mountains in the northeastern part of Kanto, from Hakone in Kanagawa prefecture to Tama region in Tokyo and Chichibu region in Saitama prefecture 20 Centi
▽ 10 cm in the plains of
northeastern Kanto ▽ It is expected to be 5 cm in the plains of southern Kanto and the 23 wards of Tokyo.
After that, the amount of snow that falls in the 24 hours from the morning of the 24th to the morning of the 25th is
▽ 20 cm to 40 cm in Nagano prefecture
▽ Yamanashi prefecture, Hakone in Kanagawa prefecture to Tama region in Tokyo, Saitama prefecture 10 cm to 20 cm in the Chichibu region of
▽ 5 cm to 10 cm along the mountains in the northeastern part of Kanto
▽ It is expected to be 1 cm to 5 cm in the plains of Kanto and the 23 wards of Tokyo.
The amount of snow may increase further depending on the location of the low pressure system, the degree of development, and how the temperature drops.
In addition to the impact on traffic, the Japan Meteorological Agency calls for careful attention to fall accidents caused by freezing of the road surface and snow accretion on electric wires and trees.
Also, in the Izu Islands near low pressure, very strong winds may blow from the night of the 23rd to the 24th, so be careful of strong winds and high waves.
