Cut-off low to bring cold, wet and windy weather

A powerful cut-off low-pressure system is set to bring cold, wet and windy conditions to parts of South Africa from Thursday (3 September 2026), with severe thunderstorms, flooding, damaging winds and large waves among the potential hazards.

The South African Weather Service (SAWS) said the system will develop over the western interior on Thursday, triggering a significant change in weather conditions across several provinces.

Very cold conditions are expected over high-lying areas, with maximum temperatures potentially remaining below 10°C in some places

Parts of the Western Cape could experience disruptive rainfall, with a risk of localised flooding, particularly across the south-eastern parts of the province.

Strong to damaging winds are also expected over the interior, while gale-force winds could hit the south-western and southern coastal areas.

SAWS warned that waves of between 4.5 and 5.5 metres could pose a danger to coastal activities and infrastructure.

Weather warnings issued

SAWS has issued several Yellow Level 4 warnings for Thursday and Friday:

*Disruptive rainfall and flooding: The Overberg and Garden Route districts in the Western Cape are at risk on Thursday, with flooding of roads and settlements and major traffic disruption possible.

*Damaging winds: The Namakwa District in the Northern Cape, parts of the Cape Winelands and Central Karoo, and the Little Karoo could experience damaging winds from Thursday afternoon into Friday. Temporary structures could be damaged, while flying debris could pose a danger to people and transport routes.

*Damaging winds and waves: Coastal areas between Alexander Bay and Plettenberg Bay face dangerous winds and waves that could disrupt ports and harbours and create hazardous conditions at sea.

More provinces in line for severe weather

As the system moves eastwards over the weekend, temperatures are expected to drop noticeably across parts of the Free State, Gauteng, Eastern Cape, KwaZulu-Natal and eastern North West.

Scattered to widespread showers and thundershowers, along with windy conditions, are expected from Friday into Sunday.

Severe thunderstorms possible

SAWS said there is a growing risk of severe thunderstorms developing over parts of the Free State, North West and Gauteng from Friday afternoon into Saturday evening.

The threat is expected to shift eastwards on Sunday, potentially affecting parts of Mpumalanga and KwaZulu-Natal, with the risk possibly extending into southern Limpopo.

Severe storms could bring:

-Heavy downpours and localised flooding
-Strong, potentially damaging winds
-Excessive lightning
-Hail

SAWS said the exact location and intensity of the storms will depend on how the atmospheric system develops and urged residents to monitor the latest forecasts and warnings.

Snow also possible

There is also a possibility of snowfall over the Drakensberg Mountains in the Eastern Cape on Friday morning, potentially spreading into the high-lying areas of Lesotho.

Motorists travelling through mountain passes are urged to remain alert as conditions could deteriorate rapidly, with reduced visibility, freezing temperatures and hazardous driving conditions possible.

SAWS has advised the public and small-stock farmers to take precautions, including:

-Monitor the latest SAWS forecasts, advisories and warnings.
-Never attempt to cross flooded roads, bridges or streams.
-Take extra care during heavy rain, particularly in flood-prone areas.
-Secure loose outdoor objects that could be blown away.
-Stay away from isolated trees and metal structures during thunderstorms.
-Exercise extreme caution along the coast where strong winds and high waves are expected.
-Dress warmly and take precautions to protect vulnerable people from the cold.
-Ensure livestock has adequate shelter in areas expecting very cold, wet and windy conditions.
-Motorists travelling through mountainous areas should be prepared for possible snowfall and rapidly changing road conditions.

Western Cape urged to prepare for El Niño risks


Western Cape Premier Alan Winde has urged residents to prepare for the growing risks associated with climate change and the current El Niño Southern Oscillation (ENSO) climate pattern.

Speaking during a digicon on Thursday, Winde, Western Cape Local Government, Environmental Affairs and Development Planning Minister Anton Bredell, and provincial officials outlined the province’s preparedness for possible weather-related impacts.

“The Western Cape has learned difficult lessons over the past several months and years; we must all always be prepared for the pressures of climate change and associated risks,” Winde said.

Understanding the risks

ENSO is a global climate cycle driven by changes in Pacific Ocean temperatures that can influence weather patterns around the world.

The system is currently in an El Niño phase and is expected to strengthen over the coming months. While its most severe effects in South Africa are generally felt in summer-rainfall regions, the Western Cape could still face increased temperatures, extreme heat, higher fire risks and additional pressure on water resources.

The fire risk has been compounded by a relatively dry winter so far.

Winde noted that while the province experienced severe flooding and heavy rainfall in May 2026, this does not necessarily mean enough rain fell to secure water supplies through the summer.

“We must all be aware of our water usage,” he said.

Climate modelling raises concerns


The provincial government has worked with the University of Cape Town to model future climate patterns in the Western Cape.

Karen Shippey, Chief Director of Environmental Sustainability at the Western Cape Government, said the province is experiencing significant temperature increases and an acceleration in climate change.

The modelling points to increasingly frequent and intense droughts, more hot days and fewer cold days, reduced autumn rainfall across most sub-regions, and changes in wind patterns and strength.

More than R65 million for water resilience

Western Cape dam levels are currently 5% lower than they were at the same time last year.

To strengthen water security, the provincial Department of Local Government has allocated R40.5 million through its Water Resilience Grant for the 2026/27 financial year.

A further R25.2 million has been allocated through the Groundwater and Response Programme, bringing total targeted investment in water resilience initiatives to more than R65 million.

The funding is aimed at helping municipalities improve infrastructure, reduce water losses, strengthen monitoring and management systems, and develop alternative water sources.

Winde said the province is investing proactively in preparation for future natural disasters.

“We must be more proactive and predictive in our planning. We must ensure we are prepared for any eventuality. But this responsibility does not only fall on us as a provincial government; all of us play a role,” he said.

Bredell stressed that disaster preparedness must begin before an emergency develops.

“Preparedness cannot begin when the first major wildfire breaks out, or when water systems come under pressure, or when a prolonged heatwave starts affecting vulnerable communities. By then, we are already responding to a crisis,” he said.

Graham Paulse, Head of the Department of Local Government, also stressed the importance of cooperation between municipalities, disaster management structures, stakeholders and residents to reduce the growing risk of fires.

Head of the Provincial Disaster Management Centre, Dr Colin Deiner, said disaster planning is an ongoing process and requires the support of residents.

“Our planning does not start now; it starts at the end of every summer. And we need the help of every single resident of our province,” he said.

Winde urged residents, particularly those living in high-risk areas, to prepare now.

“Where you live matters and if you know that there is a fire risk in your area, now is the time to prepare,” he said.

Icy, wet and windy conditions expected across SA this week


The South African Weather Service (SAWS) is warning of typical winter weather across large parts of South Africa this week, with a cold front being supported by an upper-air cut-off low.

SAWS said today (Tuesday, 11 August 2026), that wet, very cold and windy conditions are expected across the southern parts of the Free State, Northern Cape, Gauteng and Mpumalanga, as well as the interior of the Eastern Cape and KwaZulu-Natal.

Snowfalls are possible over mountainous areas, while rough seas and damaging coastal conditions are expected along parts of the coastline.

“Farmers and the public in general are advised to take necessary precautions,” SAWS said.
