Weather update: Storms, snow and flooding expected in South Africa this week

The South African Weather Service warns that a “spell of fairly active weather is already unfolding” this week, thanks to the development of a steep upper trough over the western and southwestern parts of SA, including storms, snow and flooding.

Weather update for the week

Western Cape

As per the South African Weather Service (SAWS) media release dated 30 September 2020, residents in the Western Cape can expect “cold, overcast and windy conditions”.

Heavy rain and localised flooding is also expected this week and will “dominate the circulation pattern”. There is also a possibility of localised flooding across the Overberg and Garden Route region.

Coastal region residents should “exercise caution” as rough sea conditions are expected as a result of strong winds. This could result in steep waves of up to six metres at times.

“It should be noted that these steep wind-seas will cause an unusual dominant wave direction. Combined with the underlying south-westerly swell, chaotic and confused seas should be expected”.

Greater Highveld region

Residents from the Free State, North-West, Gauteng and the eastern parts of Mpumalanga can expect a “spell of early summer rain in the form of scattered showers and thunderstorms.

The eastern and north-eastern parts of the country (Gauteng, western Limpopo, Mpumalanga Highveld and eastern North West province should be prepared for widespread thunderstorms.

These conditions are predicted to last from Wednesday 30 September 2020 into the weekend. The SAWS warn that these weather conditions could result in localised flooding of low-lying areas.

Possibility of snow

Thunderstorms will continue on Friday “with the possibility of these storms becoming severe in places. However, the SAWS didn’t see the need to issue alerts for severe storms at the time of publishing.

“The upper trough intensifies and cuts off over the south-western part of the country [on Thursday 1 October], resulting in further showers in the south and west, as well as possible snow over the high-lying areas of the Western and Eastern Cape”

Monitoring weather developments

The SAWS assures citizens that “weather developments are being monitored closely, using its dedicated weather radars and the Lightning Detection Network (LDN). Updates will be shared in due course.

“Should the need arise, radar-based warnings will be issued accordingly for areas considered most at risk”.
