Yellow Level 4 Warning: Severe Thunderstorms, Heavy Rain and Flooding Expected Across Parts of South Africa

Introduction

South Africans are being urged to prepare for severe weather conditions after the South African Weather Service (SAWS) issued a Yellow Level 4 warning for severe thunderstorms expected on Friday, 6 November 2026.

The warning highlights the possibility of heavy rainfall, hail, strong winds and excessive lightning, which could create dangerous conditions for residents, motorists and businesses.

Communities in Gauteng, Limpopo and Mpumalanga are among those expected to experience severe weather. Residents are encouraged to remain alert, follow official weather updates and take the necessary precautions to protect their families and property.

Which Areas Are Affected by the Yellow Level 4 Warning?

According to the weather warning, severe thunderstorms are expected over most parts of Gauteng, the south-western Highveld of Mpumalanga and the south-western parts of Limpopo.

The warning is valid from 13:00 until 23:59 on Friday, 6 November 2026.

These weather conditions could result in flooding, damage to infrastructure and settlements, and disruptions to essential services.

Residents in affected communities should prepare for sudden changes in weather, particularly during the afternoon and evening when thunderstorms may become more intense.

Heavy Rain, Hail and Strong Winds Expected

One of the biggest concerns associated with the Yellow Level 4 warning is the possibility of heavy downpours.

Intense rainfall over a short period can overwhelm drainage systems, causing water to accumulate on roads, in residential areas and in low-lying locations.

Hail is another concern, as falling ice can damage vehicles, roofs, windows and outdoor equipment.

Strong winds associated with severe thunderstorms may also cause trees to fall, damage buildings and affect electricity infrastructure.

Excessive lightning creates additional risks for people outdoors, particularly those working in open spaces or travelling during thunderstorms.

Flooding Could Disrupt Roads and Communities

Flooding remains one of the most serious potential impacts of the expected storms.

Motorists may experience difficult driving conditions due to poor visibility, slippery roads and standing water. Some roads and bridges could become dangerous or temporarily inaccessible.

Residents living near rivers, streams and low-lying areas should pay particular attention to rising water levels.

Informal settlements and communities with inadequate drainage infrastructure may also face increased risks during periods of heavy rainfall.
