Residents of Gauteng and KwaZulu Natal were told to prepare for dangerous storms. Here is what the warning said and how to stay safe next time.
If you live in Gauteng or northern KZN, you probably saw the alert pop up on your phone. The South African Weather Service (SAWS) put a Level 4 severe weather warning in place for both areas, and it ran until midnight on 6 November 2026. The big worry was a severe thunderstorm that could bring hail, strong winds, heavy rain and a lot of lightning.
That warning period has now ended, so if you’re checking the weather today, head to the official SAWS page for the latest update. Still, this one is worth a proper look. Summer storms in South Africa don’t give much notice, and the same risks come back every season.
What SAWS warned about
A Level 4 warning is not a “grab an umbrella” kind of alert. It sits near the top of the impact based scale, and it tells you the storm could actually cause damage and disruption.
SAWS said homes, informal settlements and infrastructure could be hit by localised damage. Fallen trees might slow traffic or block roads. Flooding was also possible on roads and bridges that are already prone to it. Power and communication could drop out for a short time too. On top of all that, hail, strong winds and heavy downpours could arrive together.
None of that is hard to picture. Most of us have seen what a bad storm does to a street in about twenty minutes.
Johannesburg and Tshwane face the hail risk
The alert for Johannesburg and Tshwane carried one extra danger. SAWS said there was a chance of large amounts of small hail falling over a populated area.
Small hail might sound harmless, but it isn’t. It can dent cars, shred plants and make roads slippery. It also clogs drains fast, and that’s when low streets start to flood.
Anyone who follows johannesburg weather knows how quickly a hot, still afternoon can flip. One minute it’s sunny, and an hour later the sky is nearly black. That’s exactly why the warning came with such strong language.
A simple look at who was under which warning
The warnings weren’t the same everywhere. Here’s how they broke down.
| Area | Warning level | Main concern |
|---|---|---|
| Gauteng, including Johannesburg and Tshwane | Level 4 | Severe thunderstorm, hail, flooding |
| Rustenburg and Potchefstroom | Level 2 | Severe storms |
| Richards Bay and Mtubatuba (KZN North Coast) | Level 4 | Heavy rain, localised flooding |
| Durban and Pietermaritzburg | Level 2 | Storms moving west |
SAWS also said the system was drifting west towards the Free State. So even people outside the main warning zones needed to stay alert.
What it means for KwaZulu Natal
In KZN, the Level 4 warning covered parts of the North Coast, with Richards Bay and Mtubatuba named. Durban and Pietermaritzburg were under the lower Level 2 alert.
Residents in the north of the province were asked to watch for localised flooding. That makes sense. Rivers and streams in that part of the country can rise very quickly, and a low water crossing that looks fine can turn deadly in minutes.
SAnews, the government news agency, described the Level 4 alert as covering heavy downpours, hail and severe lightning. It also said SAWS would keep watching conditions and update its warnings when needed.
How to stay safe during a storm
The good news is that SAWS’s advice is easy to follow if you think about it before the clouds roll in.
At home, stay indoors if you can. Keep away from metal objects, and switch off electrical appliances where possible. If your area could flood, move your valuables somewhere higher than the likely water line. Farmers and rural families should move livestock to higher ground.
On the road, the safest move is to stay off it altogether. If you have to travel, take extra care where water may cover the road. SAWS said people shouldn’t cross rivers or swollen streams when the water is above their ankles. If your car gets trapped in floodwater, leave it and climb to higher ground. Don’t wait for the water to rise first.
These are simple rules, but they matter. Many flood deaths happen because someone tried to drive through water that looked shallow.
Golf, fishing and lightning
This part surprises a lot of people. SAWS told residents not to play golf or go fishing during the severe weather. Golf clubs and fishing rods both conduct electricity well, and being out in the open or near water makes a lightning strike more likely.
So if you hear thunder, you’re already close enough to be in danger. Get indoors or into a vehicle with a hard roof. And please don’t shelter under a lone tree.
Power cuts and communication problems
SAWS said power supply and communication could be disrupted for a short time. Many of us already live with outages, so it’s tempting to shrug that off. But storms bring a few extra risks.
A little preparation goes a long way. Charge your phone before the storm hits and keep a torch somewhere you can find it in the dark. Save emergency numbers on paper as well as on your phone. When lightning is close, unplug sensitive devices like TVs and routers. And if you see a fallen power line, stay far away and report it to your municipality.
Why these warnings matter
Impact based warnings are more useful than old style forecasts because they tell you what a storm could do, not just how much rain might fall. A Level 4 alert is asking you to change your plans, not just pack a raincoat.
Plenty of people ignore warnings because the sky looks calm when the alert goes out. Interior storms often build through the afternoon, then hit hard and fast. A few minutes of preparation costs you nothing, and it can save you a lot of damage and stress.
Where to get updates
For forecasts and warnings, the best place is the official South African Weather Service at weathersa.co.za. It’s the easy way to confirm the weather today for your area. For wider government updates during severe events, SAnews is a reliable source.
Your local municipality and disaster management teams often share alerts on social media too. If you live in a flood prone or hail prone area, it’s worth following them.
The bottom line
This Level 4 warning showed how fast a single thunderstorm can bring hail, lightning, flooding and power cuts to Gauteng and KZN. Johannesburg, Tshwane, Richards Bay and Mtubatuba were among the places at greatest risk.
The warning period is over, but summer is only getting started. If you live or work in the city, keep an eye on johannesburg weather updates. Stay off flooded roads, keep your phone charged and follow the official advice. It’s simple, and it works.
