· The South African
KwaZulu-Natal residents are being urged to brace themselves as a fast-moving weather system sweeps across the province this week, bringing damaging winds, storms and a sharp drop in temperature right into the weekend.

WHAT’S BEEN ISSUED
The South African Weather Service (SAWS) has issued a Yellow Level 4 warning for severe thunderstorms across the southern parts of KZN, including areas south of Underberg and Pietermaritzburg, valid for Friday, 4 September.
A separate Yellow Level 4 warning for damaging winds has also been issued for most of the province, with the exception of the south-west. According to SAWS forecaster Masego Nhlapo, wind speeds in affected areas could reach up to 90 kilometres an hour.
WHY THIS IS HAPPENING
The system driving this week’s chaos is a cut-off low-pressure system, a weather feature notorious for triggering rapid, disruptive changes as South Africa moves into meteorological spring. SAWS forecaster Sihle Dlamini explained that a 30% chance of showers was expected over the far south of the province on Thursday evening, with conditions worsening significantly into Friday.
By the weekend, the system is expected to shift eastward, bringing scattered to widespread showers and thundershowers, windy conditions, and a noticeable drop in temperatures across KZN, alongside parts of the Free State, Gauteng and the Eastern Cape.
WHAT TO EXPECT ON THE GROUND
For Newcastle and surrounding areas, this translates into partly cloudy, windy and cold-to-cool conditions, with isolated to scattered showers and thundershowers expected, becoming more widespread in the south-eastern parts of the province on Friday.
The damaging winds warning brings its own set of risks. SAWS has cautioned that affected areas could see disruptions to power and communication lines, damage to informal settlements and structures, and danger to pedestrians and motorists from flying debris. High-sided vehicles have been specifically flagged as vulnerable to serious crosswind hazards on exposed routes.
Coastal communities aren’t off the hook either, with a further Yellow Level 4 warning covering damaging winds and waves along the KZN coastline, posing risks to ports, harbours and sea navigation.
HOW TO STAY SAFE
SAWS has urged residents across the affected areas to avoid unnecessary travel during peak storm activity, steer clear of rivers and low-lying bridges prone to rapid flooding, and secure any loose outdoor items before the weather turns.
Motorists heading through the province’s mountainous and high-lying areas should stay alert for suddenly changing conditions, including reduced visibility, and should not rule out the possibility of snowfall at higher elevations as temperatures drop.
As always with cut-off low systems, the exact intensity and path can shift, so SAWS is encouraging KZN residents to keep checking official updates rather than relying on a single forecast.
“The exact location and intensity of severe thunderstorms will depend on the evolution of the atmospheric system, and the public is encouraged to remain updated with the latest forecasts and warnings,” the weather service said.
