I went to South Africa over Christmas in 1995. One of my memories from Christmas Eve was the thunderstorm in Ermelo on Christmas Eve. I turned 10 years old on that trip as well.
Been living with such storms all my life. Central and eastern south africa gets a lot of severe thunderstorms during the storm season and just 2 days ago there was a tornado near Ermelo.
By far not as much as in the USA. But 2 I do know of here in South Africa, however most videos they have are on facebook. 1 of them living in the same city as me, called: Storm Report SA
I've never in my life seen that much snow! This part of South Africa has very dry winters but freezing temperatures and frost is common. So if it does snow it's usually light.
This storm actually built up fast, I'd say around 30 minutes. It lasted for about 10 minutes but was followed by more storms from behind, so it was storming for about 2hours.
