According to the City's disaster management spokesperson, Charlotte Powell, a gale force north-westerly wind of between 60 to 65 km/h is expected between Cape Columbine, on the west coast, and Cape Agulhas, on the south coast, on Tuesday evening.

"Strong to gale force interior winds (55 to 75 km/h) and gusting winds (65 to 85 km/h) are expected over the Cape Metropole on Wednesday," said Powell.

Very rough seas are expected from Wednesday morning, with wave heights of 4 to 5m, reaching 6 to 7m between Cape Columbine and Cape Agulhas.
