As the low pressure system passes through while developing, it will snow and rain over a wide area of ​​Kanto Koshin on the 10th, and there is a risk that it will accumulate in the plains of the south such as the 23rd ward of Tokyo.


The Japan Meteorological Agency is calling for confirmation of the latest weather information and preparations.

According to the Japan Meteorological Agency, a cyclone that occurs off the coast of Tokaido on the 10th is expected to move eastward while developing near the southern coast of Honshu and pass near the Kanto region.



Due to the effects of low pressure and cold air in the sky, it is expected that it will snow and rain over a wide area of ​​Kanto Koshin from the 10th to the 11th. It is expected to snow in the south.



The amount of snow that falls in the 24 hours from the evening of the 9th to the evening of the 10th

is expected to be


20 cm to 40 cm in Yamanashi prefecture and 10 cm to 20 cm in Nagano prefecture.

For the Kanto region such as Tokyo's 23 wards, the forecast of snowfall has not yet been announced, but if it is expected that snow or rain will fall and a low pressure system develops or the temperature drops below the forecast, heavy snow may accumulate. there is.

In the Kanto region, even a small amount of snow may significantly disturb the transportation schedule or cause a car slip accident, and in the past, due to the freezing of the road surface, there have been a series of injuries due to falls while walking.

The Japan Meteorological Agency is calling for early preparation, such as checking the latest weather information, paying attention to the impact of snow on traffic, and preparing chains for tires and shovels for shoveling snow.








Information Liaison Office at the Crisis Management Center at the Prime Minister's Office

It is expected that it will snow and rain over a wide area of ​​the Kanto region from the 10th to the 11th, and in response to the possibility that snow will accumulate in the 23 wards of Tokyo, the government announced at 4:45 pm on the 8th at the Prime Minister's Office. We have set up an information liaison office at the Crisis Management Center to collect information and be alert.

Damage and countermeasures to be aware of in urban areas with little snow

After the 10th, there is a risk of heavy snowfall and low temperatures even in the southern part of the Kanto region such as the 23rd ward of Tokyo.



We have summarized the precautions and countermeasures in urban areas where it usually does not snow much.



The first thing to watch out for is a fall while walking due to snow or freezing of the road surface.



Especially in areas where you are not accustomed to snow, you may get serious injuries.



During the heavy snowfall last month, when the snowfall was 10 cm in central Tokyo and 8 cm in Tsukuba, Ibaraki Prefecture, pedestrians and bicycles fell one after another, and more than 500 people in Tokyo alone had their heads and waists. I was injured by hitting a bicycle and was taken to the hospital.



When walking on a snowy road, you need to pay attention to the following points.



□ Avoid leather shoes and sneakers.



□ Wear non-slip shoes with grooves on the bottom or shoes with non-slip.



□ Reduce your stride length (penguins walking).



□ Walk with the entire sole of your shoes on the ground.



□ Free both hands with a rucksack.



□ Wear gloves and a hat to soften the impact of falling.



□ When you fall, start from your hips.



Particular attention should be paid to pedestrian crossings (above the white line), slopes, roadsides, pedestrian bridges, shade, parking lots, and entrances to underground malls.



Even if it looks like there is no snow, the road surface may freeze and become slippery when it gets cold.



Check the condition of the road surface carefully and walk carefully.

Install "winter tires" and "tire chains"

Car slip accidents and large-scale stalling are not just problems in snowy areas.



The heavy snow last month caused a truck rollover on the Metropolitan Expressway, and some roads were stuck for about 10 hours.



The first thing to check when driving a car is the preparation of "winter tires" and "tire chains".



Driving on snowy roads with summer tires is extremely dangerous, and slipping can lead to accidents and traffic jams.



If you have already replaced your winter tires, check again to see if the rubber is worn.



It is safe to load the following items in your car in advance in case you get stuck.



□ Winter clothes (thick coat, gloves, blanket, body warmer)


□ Scoop


□ Water and food


□ Portable toilet



Heavy snow may affect transportation.



When using public transportation, it is effective to make a schedule with more time than usual and not to go out forcibly, such as changing the plan.

The point is the trend of "South Bank Low Pressure"

It is expected that there will be heavy snowfall in the Kanto Koshin region after the 10th, but the point is the trend of the "South Bank Low Pressure".



According to the Japan Meteorological Agency, a cyclone will occur off the coast of Tokaido by the morning of the 10th, and it is expected to move east along the southern coast of the Kanto region while developing.



This "South Bank Cyclone" is known to be a major factor in heavy snowfall in the Kanto region, but even a slight change in the "course" or "degree of development" can significantly change the amount of rain, snow, or snow. , It is said that accurate prediction is difficult.



So what will happen to the snow this time?



First is the "course".



The south bank low pressure is likely to travel near Hachijojima in the Izu Islands from the 10th to the 11th.



When traveling near Hachijojima, the precipitation area that extends to the north of the low pressure system is likely to hit the Kanto region, and heavy snowfall is likely to occur in Tokyo and other areas.



Next is the "degree of development".



When a low pressure system develops, it draws in cold air from the north and the temperature drops near the ground, making it easier for snow to fall, but if the degree of development is weak, it will rain.



Regarding the prediction of the development of low pressure, the Japan Meteorological Agency says that there is a high degree of uncertainty at this time and it is difficult to accurately predict whether it is snow or rain.



If a low pressure system develops and snow spreads over a wide area, the amount of snowfall in half a day may reach the standard of heavy snow warning of 10 cm even in the 23 wards of Tokyo, and we are calling for early preparation.
