Weather Extremes in Tasmania

There's been a lot of vague comments regarding the extremes of weather in Tasmania at all times of year in many forum topics. However, there's not been a lot of specific examples as yet.
What are some of the extreme weather conditions that you've experienced while bushwalking in Tasmania?
I'd particularly like to see some examples of harsh weather in Summer, but extremes of winter would also be interesting to see here.
As for myself, I've not experienced weather as bad as others I've heard from.
I've had about 3cm of snow on January 26th in the Walls of Jerusalem one year, and 3cm on February 28th in the Walls of Jerusalem another year.
I've seen about 30cm of snow on the Overland Track while doing a Lees Paddocks, Reedy Lake, Kia Ora, Mersey River circuit in late November, so that's about the beginning of Summer. I know it was fresh snow, because it wasn't there when I did another walk which overlapped the same area a few weeks earlier.
So that's a quick example of snow falls occurring at any time in summer (one being a moderately substantial fall).
I've also been on Shelf Camp (next to Mt Anne) in mid-March (ie, the end of Summer) on what started off as a perfectly calm evening, but during the night a wind storm came up which caused the large pole on my old tunnel-tent to hit me in the face repeatedly during the night while trying to sleep (it kept springing back and didn't break, thankfully). When I got up in the morning, I had one foot in the tent, and one foot out of the tent when it blew away, thankfully I caught it with the one foot still in the tent, but it did tear along one of the seams in the process. I would estimate that the wind was well over 50 knots (I've sailboarded in 45 knots, and it was somewhat stronger than that). When walking out across the plateau, it was actually quite humorous to watch the line of walkers in our party all fall over at the same time every time a gust of wind hit (including myself) - sure was glad to get back to High Camp Hut for a break!
Not from personal experience, but my brother was doing the Mt Anne circuit another time during summer with two other people, and the others' tent blew away completely never to be seen again!!! They all had to cram into the one tent for the remainder of the trip.
