The Nelson Mandela Metro said shelters are open to communities from Katrina Felix Hall (Thornhill) and Loerie Community Hall.
Farmers are strongly advised to urgently relocate livestock, farming equipment, machinery and vehicles to safer areas to avoid severe flood damage.
This is due to the Kouga Dam exceeding its full capacity and now at 113%, resulting in a serious flood risk to surrounding communities.
Communities urged to evacuate are from Kingsway Village, Big Fish, Gamtoos Mouth Resort, Ferry Hotel and all low-lying areas in the Gamtoos Valley.
The Metro urged residents to avoid all river crossings and flooded roads.
