Weather warnings for 29 April 2026
Impact-based warnings
The weather service has issued a yellow level 2 warning for severe thunderstorms with heavy downpours, leading to localised flooding and damages to susceptible formal and informal settlements and infrastructure in the western parts of the North West, northwestern parts of the Free State and the northeastern parts of the Northern Cape.
Saws has also issued a yellow level 1 warning for damaging waves between Port Edward and Kosi Bay in KwaZulu-Natal.
This could result in localised disruption of small harbours and/or ports for a short period of time, small vessels being at risk of taking on water and capsizing in a locality, and difficulty in navigation at sea.
Advisories
Expect conditions that are favourable for the first frost of the season along the Lesotho border, the southern parts of both the Free State and Northern Cape, and the northern parts of the Eastern Cape.
