The South African Weather Service is expecting a well-developed cold front to pass over the country over the weekend.
This will result in hazardous weather along the coastal areas from Table Bay to Port Alfred.
Weather phenomena such as gale force winds, high seas and possible storm surges or destructive coastal waves could result in damage to boats and/or infrastructure at sea and along the coast.
A rapidly deepening low pressure system associated with a cold front will pass through the Western and Eastern Cape from Friday the 22nd through until Saturday 23rd April 2016.
Strong to gale force north-westerly to westerly winds, high seas and the progression of the cold front combined with the rapidly intensifying low pressure system and spring tides, may result in storm surges or destructive coastal waves along the Cape South and South East coast from Table Bay on Friday afternoon spreading along the South and South East coast reaching Port Alfred by Saturday evening.
Big swells are expected to batter the Jeffreys Bay coastline and could signal the start of the winter wave season.
