Johannesburg woke to a bitterly cold, wet winter morning on Tuesday, with rain falling across the city and temperatures struggling to climb above freezing. Across the country, snow blanketed parts of the Eastern Cape and KwaZulu-Natal, mountain passes were closed and motorists faced hazardous conditions, while rain and strong winds swept across large parts of the interior. Rather, it was the combination and positioning of the cold front and an upper-air cut-off low that has amplified the impacts. Again, the cut-off low on its own is also bringing cold weather, disruptive rainfall and all these characteristics are the same. The cold front has moved out of the country, leaving its remnants and a lingering pool of cold air.
