Today, the 23rd (Tuesday), the coldest air of the season moved south, causing intermittent snowfall and increasing snowfall across a wide area of western Japan, including Kyushu and China. The cold air will peak from tonight until tomorrow, the 24th (Wednesday), and there is a risk of snowfall in the Nobi Plain, including Nagoya City, and the Kansai region, and areas such as Hokuriku should be on guard against heavy snow.
Extremely cold air will move south tonight
Snow clouds are developing as cold air, which can bring heavy snow, is moving south with temperatures below -36 degrees Celsius at around 5,500 meters above the ground. Snow has fallen in various parts of western Japan, and not only the northern part of Kyushu but also southern parts such as Kagoshima Prefecture are also covered in snow. Active snow clouds are covering the Hokuriku region, and the snow is increasing locally.
As of 3:00 p.m., 3 cm of snow had fallen in Sakaiminato City, Tottori Prefecture, 34 cm in Kitahiroshima Town and Yahata, Hiroshima Prefecture, and 1 cm in Kanazawa City. A blizzard warning, strong wind warning, and heavy snow warning were announced for Nagasaki Prefecture just before 3 p.m.
Snowfall in Kyushu, Chugoku, and Shikoku is expected to increase in intensity from the evening onwards, and combined with the drop in temperature, snowfall will rapidly increase. In addition, heavy snowfall of 5 to 10 cm per hour is expected in Hokuriku, where active snow clouds associated with the JPCZ (Japan Sea Polar Air Mass Convergence Zone) are present.

There is a risk of snow on the roads even in Nagoya city.
As the strong cold air moves southward, snow clouds will develop, so tomorrow it will not remain on the Sea of Japan side but will also spread to the Pacific Ocean side. As the wind direction shifts to the northwest, snow clouds will more easily flow into the Nobi Plains from near Wakasa Bay, and snow is expected to fall in earnest around Nagoya City.
In addition, snow will spread not only to the northern part of the Kinki region but also to the central part, and there is a possibility that it will snow heavily even within Kyoto City. Heavy snow is expected even in the southern part of Shiga Prefecture, which is the path of snow clouds. Although it may snow temporarily in Osaka city, it is not expected to fall to the extent that it will accumulate.
More than 1m of snow has fallen along the mountains.
The increase in snowfall from now until the evening of the 26th (Friday) is expected to exceed 1 meter in some places, including along the mountains of Hokuriku, where it will be the most. The snow is expected to reach more than 50 cm in wide areas from Hokkaido and Tohoku to Hokuriku, and from northern Kinki to the San’in mountains, making it the heaviest snowfall of the season.
A sudden increase in snowfall could lead to strandings and large-scale vehicle backlogs. If you need to move, you need to be prepared to avoid getting stuck, such as winter tires and chains.
More than 30 cm of snow is expected to fall in areas affected by the Noto Peninsula earthquake, and there is a risk that houses damaged by the earthquake may collapse. Please spend tonight in a place where there is no danger of collapse.
Snow will accumulate over a wide area in Kyushu and Shikoku, with some snow clouds extending as far as the Pacific Ocean, and snow is expected to accumulate in the Nobi Plains and Kansai area, including Nagoya City. Avoid driving with normal tires when the roads are covered in snow.
Winds will blow across a wide area of the country tomorrow.
Winds are increasing in many places, with gusts of over 25 m/s blowing momentarily in coastal areas of Hokkaido, especially near the developed low pressure system.
Strong winds will continue from now until tomorrow, averaging 15 to 20 m/s along the coasts of western and northern Japan. Winds are expected to gust at around 25 m/s depending on the location.
Please be careful in areas where it snows, as blizzards may reduce visibility and cause whiteouts. Even on the Pacific side, where the weather is sunny, the strong cold winds will lower the perceived temperature, making it bitterly cold.
