Intense cold waves hit Hokkaido at the end of the year The impact continues until the beginning of the year
Extremely strong cold air, which can be called a “year-end cold snap”, is expected to continue to flow in the vicinity of Japan later this year from the end of the year to the beginning of the year. Let’s take a closer look at next week’s weather.
Tomorrow (26) there will be a snowstorm on the side of the Sea of Japan
Tomorrow, the winter-type pressure distribution will get stronger near Hokkaido, and the strong cold winter air will flow into the sky. Therefore, it is easy to snow mainly on the Sea of Japan side. The wind from west to west-northwest is easy to blow and there is a risk that the snow will intensify mainly in the Rume, Kamikawa, Sorachi and Goshi regions. Snow clouds are likely to enter the area around Iwamizawa, which has turned into a record heavy snowfall, and there is a possibility that it will be hit again by heavy snowfall, so caution is likely required. Even around Sapporo, there will be time for snow to fall around noon. Furthermore, due to the greater winter-type pressure distribution, the wind is strong along the coast and there is a risk of a snowstorm in the northern part of Ishikari and the Rumo region. Tomorrow, we must watch out for traffic obstacles caused by blizzards and puddles, and watch out for heavy snowfall.
27-29 The cold air in the sky once relaxes
The pressure distribution around Hokkaido on the 27th is winter-like, but the cold mid-winter air will gradually escape. There are places where it snows, mainly on the Sea of Japan side, but the way it rains is weakening, and there are expected to be many places where it will pass gently in winter.
The 28th will be in a valley with little pressure, but the weather will not change much, so this day is recommended for shopping during the end of the year and end of the year holidays.
Around Hokkaido on the 29th, the pressure valley will pass to the east. The temperature is expected to return to normal during the day from 28 to 29. Some people may be planning to remove snow from the roof in preparation for the next snow, but watch out for falling snow and make sure two or more people clear snow to ensure a lifeguard for safety. Please use it. Also, be careful when walking under eaves.
In the afternoon of the 29th the next pressure valley will approach. For this reason, it is expected that it will be easier to snow again from the west.
30 to 1 “New Year’s cold wave” invades Strong winter-type pressure distribution
On the 30th it will pass the valley of pressure. After going through the pressure valley, there will be very strong cold air that only enters a few times a year. This cold air is likely to linger for years to become a “year-end cold snap” rather than a year-end cold snap. Due to this effect, the temperature will be significantly lower than normal from day 30, and it will be very cold. Snow will increase intermittently on the Sea of Japan side and on the Sea of Okhotsk side, causing heavy local snowfall. From 13 to 21, snow increased intermittently in Iwamizawa, causing a record of heavy snowfall. The characteristic of the snow caused by this cold wave is that the places where the snow becomes stronger move one after another. Since the wind direction is not constant, the place where the snow clouds generated in the Sea of Japan enter will move. For this reason, there is a risk that the snow will intensify even around Sapporo, where there was little snow last time. You need to pay attention to traffic obstacles due to heavy snowfall in a wide area.
