Weather warnings, Saturday, 18 October
Impact-based warnings
The weather service has issued a yellow level 2 warning for severe thunderstorms over most parts of the Free State, western parts of North West and KwaZulu-Natal, and north-eastern parts of the Northern Cape. This could result in strong damaging winds, large amounts of small or large hail in open areas. Expect heavy downpours leading to localised flooding of susceptible areas (settlements, roads and bridges), and excessive lightning.
A yellow level 1 warning has also been issued for damaging winds resulting in localised disruption of small harbours or ports for a short period of time along the KwaZulu-Natal coast between Port Edward and Durban. Small vessels are at risk of taking on water and capsizing in a locality and difficulty in navigation is expected.
Fire danger warnings
Expect extremely high fire danger in the Eastern Cape’s Walter Sisulu Local Municipality.
