Strong thunderstorms with heavy rain, damaging winds, hail, and lightning are expected across most of KwaZulu-Natal and in the far northern areas of the Eastern Cape on Monday.
A Yellow Level 2 warning has been issued for these areas, which may lead to localized flooding and damage to infrastructure and settlements. However, the northeastern part of KwaZulu-Natal is excluded from this warning.
A Yellow Level 1 warning regarding damaging winds is in effect separately for the western part of the Free State and the far eastern Northern Cape.
Weather and fire hazard warnings
The warnings emphasize the following potential consequences: strong thunderstorms may cause localized flooding and damage infrastructure and settlements in affected parts of KwaZulu-Natal and the Eastern Cape.
Damaging winds are capable of causing local damage to settlements and agricultural production in the western part of the Free State and the far eastern Northern Cape. Furthermore, transport routes and services may be affected by wind, falling trees, or dust storms.
Extremely high fire danger is expected in the North-West, central and eastern parts of the Northern Cape, most of the Free State and Limpopo, as well as in some areas of western KwaZulu-Natal and western Northern Cape.
