Weather Alert: Thunderstorms in KwaZulu-Natal and Fire Danger Across Five Provinces

The South African Weather Service (SAWS) has sounded a weather alert for Saturday, 13 September 2025, warning of severe thunderstorms in KwaZulu-Natal and extreme fire danger conditions in five provinces. Communities have been urged to stay alert as the weather could disrupt transport, damage infrastructure, and put public safety at risk.

Severe Thunderstorms Expected in KwaZulu-Natal

KwaZulu-Natal faces a yellow level 2 warning for severe thunderstorms, excluding the far north. Meteorologists say residents should prepare for:

• Flooding on vulnerable roads and bridges
• Damage to homes and infrastructure in low-lying areas
• Treacherous driving conditions caused by slick roads and poor visibility

The province has already endured a week of unstable weather, and authorities have emergency crews on standby. “Motorists and homeowners must take extreme care. Heavy downpours can trigger flash floods in minutes,” warned SAWS officials.

Weather Alert: Fire Danger Stretches Across Five Provinces

While KwaZulu-Natal braces for storms, Limpopo, Mpumalanga, North West, Free State, and the Northern Cape face a different threat: runaway fires. SAWS flagged exceptionally high fire danger for:

• The Lowveld of Mpumalanga and Limpopo
• The western stretches of the North West and the Free State
• The central and eastern Northern Cape

Dry brush and strong winds create the perfect recipe for veld fires. Farmers and residents have been urged to hold back from lighting fires or burning refuse. As SAWS cautioned, “A single spark can fuel a blaze that spreads out of control within minutes.”

Gauteng: Heat With a Stormy Twist

Gauteng residents will wake up to fine and warm weather, but the sky is expected to cloud over in the afternoon. Showers and thundershowers are likely in the south.

The UVB sunburn index sits at ‘very high’, meaning unprotected skin could burn quickly. Health experts are advising people outdoors to use sunscreen, wear hats, and take shaded breaks.

Weather Alert Across South Africa

Mpumalanga:

Clear skies will dominate the northern Lowveld, while the southern Highveld sees partly cloudy, warm to hot conditions with isolated afternoon thundershowers.

Limpopo:

A hot morning sets the tone before cloud cover builds over the south. Dry northern conditions continue to feed the fire risk.

North West:

Expect partly cloudy, hot, and windy conditions. Showers and thundershowers are likely in the west, adding to the fire threat.

Free State:

The province will be windy and partly cloudy, with cool to warm temperatures. Scattered showers and thundershowers to be expected in the far south-west, with isolated showers elsewhere.

Northern Cape:

Residents in the west can expect clear skies, though fog may form in the morning along the coast. The east will be hot, windy, and partly cloudy, with scattered storms. The south-west remains cool to cold.

Western Cape:

Morning fog will lift in the north-west, giving way to fine conditions. Other areas will be cloudy to partly cloudy with showers and thundershowers along the south coast and north-eastern interior. The UVB index is also ‘very high’.

Eastern Cape (Western half):

A cloudy and cool day is on the cards with scattered showers and thundershowers. The north will see lighter rainfall with isolated showers.

Eastern Cape (Eastern half):

Conditions worsen here, with widespread showers and thundershowers expected. Communities in flood-prone areas are advised to take extra precautions.

KwaZulu-Natal:

Morning fog patches may slow down travel in the interior. The rest of the province will be partly cloudy and warm, cooler in the south. Scattered storms are forecast, except in the far north, where rainfall will remain isolated.

Why The Warnings Matter

Spring weather in South Africa often swings between flooding rains and fire-prone heat. This weekend captures both extremes.

For farmers, veld fires threaten grazing lands, crops, and livestock. In KwaZulu-Natal, heavy downpours could wash away early harvests. For everyday residents, flooded roads, power disruptions, and fire hazards raise serious risks.

Meteorologists stress that preparation saves lives. Avoid risky driving in storm-hit areas, stay cool during heat spells, and keep flames off open ground in fire zones.

• Check SAWS updates daily
• Use sun protection outdoors
• Drive cautiously in storms and avoid open fires

South Africans enter the weekend under sharp contrasts – searing heat inland, stormy skies on the coast. Both demand vigilance.
