The South African Weather Service has forecast a high risk of fires in at least four provinces, but cold, wet and windy conditions are expected elsewhere in the country.

Impact-based warnings 

An Orange Level 5 warning for a storm surge has been issued for the coast between Plettenberg Bay and Buffalo City, leading to flooding of low-level coastal regions, especially estuaries.

Disruptions to small harbours/ports and damage to beaches, dunes and estuaries – as well as breaching of river banks upstream – are also expected.

A Yellow Level 2 warning has been issued for disruptive rain resulting in flooding of roads and susceptible settlements, as well as vehicle accidents due to slippery roads and reduced visibility over the south-western parts of the Western Cape.

A Yellow Level 2 warning for damaging winds and waves leading to difficulty in navigation at sea of small vessels and personal watercraft has been issued for between Plettenberg Bay and East London.

Fire danger warnings

Extremely high fire danger conditions are expected in Limpopo’s Modimolle Local Municipality, the eastern parts of the Free State and North West, and the southern parts of Gauteng.
