I have always said we are lucky in SA with our weather not having extreme type of weather condition but seems things are changing this side. Now I have not really heard of us having tornadoes before but reading this seem we have.

Johannesburg - Two children were killed and more than 200 people injured when storms wreaked havoc across parts of country, but a forecaster on Monday said it was not unusual weather.

Tornadoes in spring and summer were not uncommon, the SA Weather Service's Puseletso Mofokeng said.

"It happens from time to time. Over the past three years it has happened on a yearly basis."

He explained that some tornadoes happened in unpopulated areas.

"It's only when they reach cities that we notice them."

Tornadoes were more common in the central Eastern Cape, KwaZulu-Natal and the Free State. He explained that tornadoes were a by-product of a mesocyclone (a small low pressure system) which caused a severe storm. These storms, in their extreme form, could result in tornadoes.

Mofokeng said the system which caused the severe weather over the weekend would shift to Limpopo, Mpumalanga and KwaZulu-Natal on Monday. However Gauteng could still expect rain.

An eight-year-old child died and 166 people were injured when a tornado hit Duduza outside Nigel, south-east of Johannesburg on Sunday, Ekurhuleni spokesperson Justice Mohale said.

A nine-year-old boy was killed in Ficksburg early on Monday morning when the wall of his house collapsed on him during a storm in the Free State town, police spokesman Captain Phumelelo Dlamini said.

The storm hit around 02:00 and destroyed Jama Mokhekhe's house, seriously injuring other members of his family.

In the area, 42 people were injured and 122 RDP houses and shacks destroyed.

The injured were taken to hospitals in Bethlehem and Bloemfontein.

On Sunday evening two people were killed by lightning in KwaZulu-Natal’s Estcourt area, the provincial co-operative governance department said.

"Two people were killed by lightning and eight have been admitted to hospital," department spokesperson Vernon Mchunu said.

MEC Nomusa Dube would visit the area on Monday morning to assess the damage and hand lightning conductors to residents.

Tornados in Canada were all but unheard of decades ago, but over the past few years some small ones have touched down in central Canada and done damage.
Things are changing and probably not for the better.
 
We had a huge storm here in Joburg yesterday afternoon. Hail, very strong winds - I thought we were going to lose roof tiles again. The hail stones were fairly big but very jagged - we normally get smooth round hail stones. These were wicked looking things. But we were fine - no damage to the house this time - some plants in the garden look a miserable and worse for wear though - guess I'll be pruning this weekend.

But really bad in the areas the tornadoes struck.
 
the global climate is changing for sure ! the last 3 days have seen us have 30c i say again 30c !!!!!!! un heard of this time of the year . and just today 11c hows that for a swing ! snow tomorrow !
you just dont know whats next :y78:

This sounds somewhat like the yo-yo weather we've been getting over that last decade here on the eastern coast of Canada.
There was a time when winter set in and you had a good 6, 7, maybe 8 weeks of steady, very cold weather.
There would be the occasional "January thaw", but it was fairly rare.
These days the temp can be down in the -14 - 15C (5-6F) range and a day later it would be above freezing - and then back down again.
When I retired 20 years ago I could look forward to a solid, very cold spell in January and February. That was winter time here - but not anymore.
-18 - 20C (0 to -4F) was common and we got used to it. I don't think it has hit -20C in several years.
But don't get me wrong, we still get pretty cold days in the winter time :y2:
 
:y23::y23: well, I guess it's all about what you're used to.
When the really cold weather arrives we just adapt to it and that's the way it is.
But that's not to say that we like it, enjoy it or look forward to it.
It comes and it goes.
Today, after Ophelia passed by, it's 20C (68F) and a really nice day. Slighty warmer than usual for early October.
 
This was the one that cased a lot of damage, never seen something like this in SA before :y7:

I wonder if there are more tornadoes than there used to be or is it a product of greater population, less isolated areas and faster communications?

BINGO. The technology has advanced so much they can now see the rotation in the thunderstorms even if they don't produce a funnel cloud. After some storms they relook at the data to see if what in the past would have just been high winds to see if it was a tornado. Many times they are reclassified when in the past it would have just been high winds.

Population growth also plays a big part in the number of tornados, more folks to see more tornados in isolated areas plus improve communication equipment. It's all Al Gore's fault for inventing the Internet.
