What is the weather forecast for Japan from January 8th to 10th?
From January 8th to 10th, a strong cold air mass will flow into the upper atmosphere over Japan, leading to heavy snowfall, especially on the Sea of Japan side of Honshu. Snow is expected to continue, with significant accumulation even in flat areas. The Japan Meteorological Agency warns of potential heavy snow in regions like Tohoku, Hokuriku, and Tokai, particularly in Gifu Prefecture.
What precautions are recommended for drivers during the heavy snowfall?
Drivers are advised to equip their vehicles with winter tires or chains, carry shovels and sand, and avoid sudden acceleration or braking. If stranded, it is crucial to prevent carbon monoxide poisoning by turning off the engine and clearing snow around the exhaust pipe. Stretching inside the vehicle is also recommended to prevent economy class syndrome.
What are the potential impacts of the heavy snowfall on transportation?
The heavy snowfall is expected to cause vehicle standstills, road closures, and significant delays or cancellations of public transportation. Last year, a similar situation on the Meishin Expressway near Sekigahara Interchange led to a 34-hour road closure. Preventive road closures may be implemented on highways and parallel national roads to avoid large-scale vehicle congestion.
What is the JPCZ, and how does it affect snowfall in Japan?
The JPCZ (Japan Sea Polar Air Mass Convergence Zone) is a band of developed snow clouds that forms over the Sea of Japan. It is known to cause heavy snowfall when winds collide, leading to active snow clouds. This phenomenon is expected to bring significant snow to regions like Hokuriku, Niigata, and southern Tohoku, with the potential for rapid snow accumulation if the clouds remain stationary.
What are the expected snow accumulations in various regions of Japan?
Over the next 24 hours, Niigata, Hokuriku, Tohoku, and Gifu Prefecture are expected to receive up to 70 cm of snow. Other regions like Chugoku may see 50 cm, Hokkaido 40 cm, Kinki 35 cm, Shikoku 20 cm, and northern Kyushu 5 cm. Snowfall is expected to continue, with further accumulation in the following 24 hours.
What measures are being taken by logistics companies due to the heavy snowfall?
Logistics companies like Yamato Transport and Sagawa Express are experiencing delays in deliveries, particularly in Aomori Prefecture. Some areas, such as Aomori City and Hirosaki City, have suspended deliveries entirely. Companies are warning of potential delays in other regions like Hokkaido, depending on weather conditions.
What is the significance of the joint press conference by the Japan Meteorological Agency and the Ministry of Land, Infrastructure, Transport and Tourism?
The joint press conference highlights the severity of the upcoming snowfall and the need for public preparedness. It is the first such conference this season, reflecting the heightened concern over the potential impacts of heavy snow on transportation, infrastructure, and daily life.
What are the risks associated with heavy snowfall beyond transportation disruptions?
Beyond transportation issues, heavy snowfall poses risks such as roof avalanches, snow accumulation on power lines and trees leading to power outages, and the potential for avalanches. The Japan Meteorological Agency urges caution and preparedness for these hazards.
