An atmospheric monster has blossomed in the western Pacific Ocean, and it could have a devastating impact
on Hong Kong this weekend.
On Thursday, Super Typhoon Usagi—now officially Earth’s strongest storm this year—rapidly grew from tropical storm strength to the equivalent of a category five hurricane, the scale’s highest level. That transformation occurred in an impressively short period of time: the storm’s estimated winds increased in speed by about 85mph (140kph) in less than a day—good enough for one of the fastest intensification rates ever recorded. Maximum wind gusts within Usagi are now estimated to be an incredible 170 knots (see below), or 195 mph (315 kph).
And it may be even stronger than that. Unlike in the Atlantic Ocean, there are no direct ‘hurricane hunter‘-style aircraft observations of typhoons in the Pacific, so we don’t really know how strong this mega-storm is. One satellite-based estimate shows the storm’s minimum central pressure to be around 882 millibars, good enough to be the planet’s strongest storm since 1984.
The Joint Typhoon Warning Center, a US Military forecasting command post in Pearl Harbor, Hawaii, said there is “high confidence” that the track of Usagi will skirt the southern tip of Taiwan on Friday and make landfall near Hong Kong late Saturday. The storm is gathering in the Pacific as Hong Kong, mainland China, and much of Asia, celebrates the mid-Autumn festival, a time when far-flung families gather and neighborhoods host outdoor carnivals.

I didn't see a thread about this. Accuweather seems to think a swath of 2-4 inches of rain will fall in Southern Ontario. I checked the weather networks site and they seem to think close to 100 millimetres will fall around my area of Chatham Kent. Seems to be a pretty strong system for August as we usually get these in the fall.
