As the cut-off low-pressure system exits along the south-eastern coastline, a surface high-pressure system is expected to ridge across the central and eastern parts of the country this weekend according to the SA Weather Service.

This weather pattern is likely to bring partly cloudy to cool conditions across many areas with isolated to scattered showers and thundershowers expected over the central and eastern interior of the country.

Warnings from the SA Weather Service from Saturday:

A. level 2 warning for severe thunderstorms accompanied by heavy downpours, lightning, damaging winds and large amounts of small hail resulting in localised flooding and damage to infrastructure and settlements are expected over the eastern parts of KwaZulu-Natal.
