Coastal Warnings: Rough Seas and Strong Winds
SAWS warns of rough seas along the coasts of the Western Cape, Eastern Cape, and KwaZulu-Natal. These conditions are expected to persist through Saturday, creating hazardous conditions for small vessels and coastal activities. A yellow level 2 warning has been issued for damaging waves between Saldanha Bay and East London, with small boats at risk of capsizing and navigation difficulties expected. Mariners and coastal communities should exercise extreme caution.
Additionally, strong damaging winds are forecast along parts of the Eastern Cape, particularly over the Kouga and Nelson Mandela Bay local municipalities. These winds may cause localised damage to formal and informal settlements and disrupt maritime operations offshore between Plettenberg Bay and East London.
High Fire Danger in Interior Provinces
The interior regions face a high fire danger warning, especially in the Northern Cape, central and western Free State, and western North West Province. Dry, windy conditions combined with low humidity increase the risk of wildfires. Residents in these areas should remain vigilant, avoid open flames, and comply with any fire restrictions issued by local authorities.
