In the second half of the week, cold weather will aggravate it
On the 6th, Sapporo is expected to have 12 consecutive days in the middle of winter, and the maximum temperature in Tokyo and Fukuoka will be below 10 ℃. The severe cold continues throughout the country. After 7 AM, it will be even colder due to the invasion of cold waves, and the cold peak will be from 8 to 9. You also need to be careful about freezing the water and the road surface.
It has been cold for 6 days in Sapporo for 12 consecutive days, and the maximum temperature in eastern and western Japan is below 10 ℃.
Even on the 6th, cold air flows into the vicinity of Japan. Around 1500 meters above the Japanese archipelago, except for the Okinawa region, it is completely covered in air below 0 ° C.
In Hokkaido and Tohoku, there are places where midwinter days with a daily maximum temperature of 0 ° C or lower continue every day. The maximum temperature until 3:00 pm on the 6th is -2.8 ℃ in Sapporo City, -1.2 ℃ in Aomori City and -0.3 ℃ in Morioka City. Aomori City and Morioka City will be midwinter days for 7 consecutive days.
Also, it was very cold during the day outside of northern Japan. The lowest temperature in each area until 3:00 pm was 6.8 ° C in central Tokyo, which was more than 4 ° C lower than yesterday.
Also, as the stronger cold air has begun to flow from the west, there are many places in western Japan where the maximum temperature has dropped below 10 ° C. The maximum temperatures in each area until 15: 00 hours are 8.9 ° C in Osaka City, 7.9 ° C in Hiroshima City, 8.3 ° C in Takamatsu City, 8.3 ° C in Fukuoka City
and 8.9 ° C in the city of Kagoshima.
(* Fukuoka City observes the highest temperature before sunrise)
Starting on the 7th morning, the cold air intake will gradually increase. It will be even more severe across the country over the weekend, as the cold air is blowing through more forcefully than the recent end-of-year cold snap.
In particular, the cold peak is from 8 to 10, and the lowest temperature in the morning will be below freezing in the entire country, except in some areas like Okinawa. On the morning of the 8th, it is expected to be -3 ℃ in Nagoya and Hiroshima.
Even during the day, Hokkaido and Tohoku are expected to have a subzero midwinter day, and there are many places where the maximum temperature does not reach 5 ° C from Tokai to Kyushu, and on the 8th, even in Hiroshima and Fukuoka, expected to rise to just 2 ° C.
During the end-of-year cold snap, water supply freezes occurred one after another in Hokkaido, but in this cold snap, it is necessary to be careful about freezing the water supply in eastern and western Japan.
When the temperature drops below -4 ° C, the water supply can freeze. However, if the water pipe is outdoors, if it is in a sunny location on the north side of the building, in a location where strong winds are likely to blow, or if it is exposed, even if the temperature does not drop below -4 ° C, The water supply is easy to freeze. Therefore, be careful on days when the temperature drops below freezing.
Also, in areas where snow or rain is expected, watch out for freezing of the road surface in addition to snow accumulation.
To prevent “water supply freeze” caused by severe cold, the following is effective.
We drain the water from the water pipe in advance. There are various types of drain plugs, so if you check the method of use in advance and check the location of the drain plug, the work of draining the water will be smooth.
Wrap exposed water pipes and outdoor meters with special tape tightly with a heat insulating material, such as foamed styrene, to keep them warm.
<参考>
Still, if the water supply freezes, leaving it frozen can cause the water line to break, and hot water can be poured directly into the tap to defrost the ice. It is also dangerous and prohibited. Be sure to check with your local government or ask a water supplier to do repair work.
