The SA Weather Service (Saws) has issued a storm warning for parts of KwaZulu-Natal for Wednesday evening.
Saws said a surface trough situated over the central interior of the country extending to the eastern parts of the country had caused high instability and surface convergence over KZN resulting in scattered showers and thundershowers over the western and southern parts.
"These thunderstorms may be severe and are expected to be accompanied by heavy downpours, strong damaging winds, hail and excessive lightning," warned Saws.

The warning is in effect from 5 pm to 9 pm. Saws added that heavy downpours may lead to localised flooding of roads and low lying bridges. There could also be localised damage to settlements and infrastructure over open areas due to strong winds. Severe lightning could possibly result in localized fire incidents, injuries to humans and livestock and there could be localised damage to vehicles due to hail.
They advised people to stay indoors, and if outdoors to seek shelter immediately but not under trees, telephone lines and power lines.
"Take caution or avoid traveling on bridges and roads in low
lying areas as these may be susceptible to flooding and there may be sinkholes.
Avoid outdoor activities as lightning may result in injuries. If possible
stay indoors well clear of windows, shelter pets, cover vehicles and
disconnect electrical appliances."
