“Very rough seas with waves in excess of 6m are predicted for the coastal areas from Wednesday,” spokesman Richard Bosman said in a statement.
Residents were urged to stay away from areas like the Atlantic Seaboard, False Bay coastline and Strand/Gordon’s Bay beachfront.
Bosman said the SA Weather Service had predicted cold and wet conditions in the country. A cold front was expected on Wednesday and snowfall anticipated in high-lying areas.
“The first of two cold fronts is expected to make landfall early tomorrow [Wednesday].”
He said the second one was expected to start developing late on Wednesday with strong onshore winds and persistent, widespread showers which could result in flooding in places.
“The City of Cape Town has put in place measures to try and mitigate the impact. Our operational staff will be on standby to assist residents in need over the next few days.”
Residents were urged to be cautious, especially on the roads. Bosman said the weather would start clearing on Friday.
