Overview
- SAWS issued six active warnings for 15 September, including Yellow Level 4 disruptive‑rain alerts for eastern Namakwa in the Northern Cape and the Central Karoo District in the Western Cape.
- A cut‑off low over the Western and Northern Cape is producing intermittent heavy downpours, small hail and lightning, and SAWS reports very rough seas of 4.0–4.5 metres south of Table Bay.
- Multiple Yellow Level 2 warnings cover severe thunderstorms and damaging winds in parts of the Western Cape, KwaZulu‑Natal, North West and other areas, with localised flooding and property damage possible.
- Authorities warn that heavy rain and gusty winds could make roads hazardous and disrupt the school run, and motorists are advised to avoid crossing flooded roads and to check local updates before travel.
- Separately, SAWS has flagged extremely high fire danger in parts of Limpopo, and a cut‑off low is a detached low‑pressure system that can linger and produce prolonged, locally intense rainfall and storms, so residents should monitor official guidance.
