Typhoons of 4th category are called "supertyphoons" and if really Korea hit supertyphoon this week, it can be the worst weather event in the region for last years.
South Korea, Japan and China already have valid warnings before a superstorm and North Korea too prepare population to hit of strong tropical system /https://www.nknews.org/2020/08/north-korea-issues-warnings-ahead-of-typhoon-bavis-touchdown-on-pyongyang//.
Typhoon will have track along west coast of Corean Peninsula and it can hit North Korea in full power. Except of west coast of South Korea, western parts of North Korea are in most danger, according to the newest forecasts.
