Tomorrow, the 2nd, the low pressure that has developed near the Soya Strait will almost become stagnant, and the gradient of the pressure near Hokkaido will increase. Extremely cold air will flow into the sky for this time of year, and snow and wind will become stronger mainly on the Sea of Japan side.
The predicted maximum instantaneous wind speed is 35 meters on land on the Sea of Japan side, creating a risk of storms. The heavy snowfall will reduce visibility and may lead to whiteout conditions in some areas. A blizzard warning is expected to be issued for the Rumoi region, northern Ishikari, southern Hiyama, Okushiri Island, and the western coast of Oshima Island, so vigilance is needed to avoid traffic impacts.
If you do go out, it is a good idea to avoid coastal roads as much as possible, and if you are traveling by car, it is a good idea to prepare cold weather gear and a shovel in case you get stranded. Also, as there is a risk that transportation may be affected, please consider rescheduling your plans to a later date and act with safety first.
There is also the risk of power outages due to power lines being cut due to strong winds, so be sure to take precautions such as making sure your cell phone or smartphone is fully charged even when you are at home.
In addition, as the temperature drops due to the effects of cold air, there is a risk of frozen roads in various places even during the day. Please be careful about slips and falls.
Depending on the trend of the low pressure system, there is a risk that the blizzard will continue for a long time.
On Sunday the 3rd, the low pressure near the Soya Strait will gradually move eastward, and the peak of the winds near Hokkaido is expected to pass. However, if the low-pressure system moves slower than expected or develops more strongly, the storm could continue into the third day and spread across the area. In addition, cold air remains in the sky, and a trough in the atmospheric pressure is expected to pass from the 3rd to the 4th, so intermittent snowfall will continue mainly on the Sea of Japan side.
It seems that you will need to pay close attention to the latest weather and traffic information from the 3rd onwards.
