The Japan Meteorological Agency has urged people to be on alert for blizzards and snowdrifts that affect traffic, storms and high waves.
On the other hand, from Tuesday the 24th to Thursday the 26th next week, the winter-type pressure pattern is expected to intensify, and the strongest cold air of this winter is expected to flow over Japan.
Heavy snow and stormy weather will occur mainly from northern Japan to the Sea of Japan side of western Japan, and warning-level heavy snow and blizzards are possible in a wide area on the Pacific side, such as Kyushu, Shikoku, and the Tokai.
Temperatures are expected to drop considerably, with the lowest temperatures expected to drop below freezing in various parts of eastern and western Japan. Heavy snowfall and frozen road surfaces will affect traffic in various parts of the country, and there is also the risk of water pipes freezing.
Please pay attention to the latest weather information and prepare early.
On the night of the 24th, a very strong chill hits Kyushu, Shikoku and Kinki
According to the Japan Meteorological Agency, from the beginning to the middle of this month, the westerly winds that flowed over Russia swirled greatly to the south, causing very strong cold air to flow in, and some locations recorded temperatures of minus 60 degrees Celsius or less.
As the westerly wind meanders southward near Japan next week, such extremely strong cold air is expected to flow in from the continent.
On the night of Tuesday the 24th, a very strong cold wind of -12 degrees Celsius or less is expected to cover Kyushu, Shikoku, and Kinki at an altitude of 1,500 meters.
In January 2016, a cold air of minus 12 degrees, similar to that expected this time, flowed over southern Kyushu, causing heavy snow in Kyushu, and snow was observed in Amami City, Kagoshima Prefecture for the first time in 115 years.
At that time, there were a series of falls and accidents in various places, and according to the summary of the Fire and Disaster Management Agency of the Ministry of Internal Affairs and Communications, 6 people died nationwide and more than 260 people were injured.
The Japan Meteorological Agency does not know the details of the snow forecast at this time, but it is possible that there will be warning-level heavy snowfall and blizzards not only on the Sea of Japan side, but also on the Pacific side of Kyushu, Shikoku, and the Tokai. increase.
In addition, the lowest temperature on the 25th
is expected to be -5
degrees Celsius in Kochi and Hiroshima, -4 degrees
in central Tokyo,
and -3 degrees in Nagoya and Miyazaki .
We are calling to be careful about freezing pipes.
To prevent "frozen water pipes"...
"Freezing of water pipes" is more likely to occur when the temperature is low.
Water outages due to frozen water pipes have occurred one after another in the past, and from January to February 2018, about 36,000 households in 10 prefectures such as the Kanto, Hokuriku, and Chugoku regions were cut off.
In addition, in January 2016, when very strong cold air similar to this forecast flowed in, causing record heavy snowfall and low temperatures in various parts of western Japan, 21 people including Kyushu, Shikoku, Chugoku, and Kinki More than 504,000 households in prefectures have had their water supply cut off.
According to the Ministry of Health, Labor and Welfare, in areas where the temperature is usually not that low, water pipes are more likely to freeze when the minimum temperature drops below -4 degrees Celsius.
In particular, water pipes that are outdoors, facing north, are prone to shade, or are exposed to strong winds, are prone to freezing.
In order to prevent freezing,
it is effective to take measures such as
covering the part exposed to the outside air with a heat insulating material or towel, and
leaving a small amount of water running.
It is also important to remove it.
If it freezes, wrap it in a towel and slowly pour lukewarm water over it to melt it.
If you pour boiling water over it, the water pipe may burst.
In addition, it is safe to store drinking water or fill the bathtub with water in case the water supply is cut off.
The Ministry of Health, Labor and Welfare said, ``Since low temperatures are expected nationwide, we want each family to prepare early.''
Government set up "Information Liaison Office" in preparation for heavy snowfall
From the 21st to the 21st, there will be a blizzard centered on the Sea of Japan side of northern Japan, and next week there is also a risk of heavy snow over a wide area including the Pacific Ocean side. We have set up a communication room to gather information and take precautions.
