Wednesday, September 2, 2020 at 7:10 PM – In Asia, tropical activity is at its height: two typhoons, one after the other, will make landfall near South Korea. Japan is at risk of being seriously affected. To a lesser extent, Canada will experience consequences that may cast a chill on the country!

Gigantic storms in the Pacific
Typhoon Maysak located in the south of South Korea on Tuesday morning reached category 4 according to the Joint Typhoon Warning Center, the tropical cyclone forecasting center between the US Navy and the US Air Force.
As this typhoon heads straight for South Korea, Haishen, another typhoon, will in turn intensify before taking a similar course.
Maysak is, for the moment, the strongest typhoon of the 2020 season, with maximum winds of 230 km / h, slightly less strong than those of Laura.
On its way, it has already spilled more than 220 mm on the Japanese islands, with gusts of more than 150 km / h. It is believed to be the strongest to make landfall in South Korea since 2012. According to NOAA, only five or more Category 2 typhoons have made landfall in that part of the world.
For its part, Haishen is currently a tropical storm. It is predicted to intensify by the weekend and become a Category 4 or higher super typhoon.
For the moment its trajectory seems to favor an impact on the coasts of southern Japan by the end of the week, or even the beginning of next week. It is still too early to certify its trajectory and its future category.
If these countries expect the worst, it is because of an atmospheric blockage in the Pacific. An area of high pressure blocked over Japan allows these typhoons to take an inland path, not eastward. But that’s not all … These typhoons threaten to upset the Canadian atmosphere!
North America is scooped
This serpentine path of the jet stream causes arctic air to flow southward. This cold is drained to Texas while the temperature anomalies are close to 10 ° C below normal. In contrast, British Columbia is expected to experience the hottest temperatures this season with highs of 30 ° C.
The weather station in Alert, Nunavut, is already recording highs below freezing. This arctic air is therefore present and can flow southwards if the atmospheric pattern lends itself to it.
Quebec at the center of a battle
While the atmospheric circulation is slowing down at altitude, Maysak then Haishen will accentuate the atmospheric ridge present in Japan but also in British Columbia. A strong temperature contrast will then be present across Canada. A struggle to end between hot and cold is emerging. For Quebec, it will be double or nothing!
