The South African Weather Service (SAWS) has issued a Yellow Level 4 warning for severe thunderstorms in southern Mpumalanga.
Heavy downpours and damaging winds could cause flooding, damage to infrastructure and major travel disruptions.
The warning takes effect at 14:00 on Monday, 26 October, and remains valid until 23:59 on Tuesday, 27 October.

Severe weather could also disrupt major transport routes, with some roads and bridges potentially closing because of flooding.
Municipal and essential services, including electricity, healthcare, education and communications, could experience disruptions.
Farmers could also face agricultural losses, including damage to livestock and livelihoods.
Staying safe during severe thunderstorms
Residents should monitor weather warnings and avoid travelling through flooded roads or bridges.
Motorists should reduce their speed during heavy rain and avoid unnecessary travel when conditions become dangerous.
People living in areas at risk of flooding should remain alert to rising water levels and follow instructions from local emergency services.
SAWS advises residents to keep checking official weather updates as conditions change.
