Weekly Weather Update 8 January 2018

The heatwave conditions across the interior and northern parts of the country are expected to continue until Tuesday, according to the South African Weather Service (SAWS).

SAWS issued a continued heatwave advisory for Monday, 8 January across the northern parts of South Africa including the Northern Cape, the Free State, the North West province and Gauteng. Temperatures are only expected to ease from Tuesday, 9 January.

It says severe storms are also possible in places as the “heat wave breaks with a drop in temperatures and the return of thundershowers in the eastern and north-eastern provinces”.

Fire dangers and gale force winds

Added to this, SAWS says extremely high fire danger warnings remains in place over the northern and eastern parts of the Northern Cape, Free State, western and southern parts of Gauteng, Limpopo’s western bushveld and Limpopo Valley as well as the  eastern parts of the North West.

Rain and thunderstorms

A watch has been issued for severe thunderstorms over the western parts of KwaZulu-Natal and the western parts of Mpumalanga.

Monday will also see widespread coastal showers, as a 30% chance of rain is expected from the Western Cape’s Cape Town through the Garden Route all along the the Eastern Cape’s Port Elizabeth and Port St John. The rain forecast for KwaZulu-Natal strengthens to a 60% chance of showers, extending from the east coast of South Africa, across the eastern most parts of Gauteng, Mpumalanga and Limpopo.

Tropical storm for Madagascar

This, as a tropical storm strengthens off the east coast of Madagascar in the Indian Ocean. SAWS says moderate tropical storm Ava has strengthened from an initial depression on Sunday 7 Janaury, bringing with it wind speeds of about 33 to 64 knots. There is no risk of the storm impacting South Africa, according to SAWS who will continue to monitor its weather patterns.

Visitors to certain areas in Limpopo, Mpumalanga and KwaZulu-Natal are also advised of a malaria risk due to extended seasonal rains.  The National Institute for Communicable Diseases released an advisory on the increased malaria risk in these three provinces earlier in December, with travellers advised to take precautionary measures.
