Do you remember? – Roll cloud draws eyes to sky
EYES all over Durban were drawn to the sky on Wednesday, 20 November (2013) as an unusual cloud formation rolled its way across the skies and preceded a flash storm in South Durban.
Where were you when this strange looking cloud rolled past?

Southlands Sun journalist Erin Hanekom reported this:
THE roll cloud, which is one of two types of arcus clouds, is identified by being low, horizontal and cylindrical in shape and isolated from other clouds.
It is rare and will only form if very specific and uncommon conditions are met. When warm air is pushed above cool, the wind direction and speed is altered, creating the cloud, which appears to roll.
Thunderstorms often follow these clouds and this was definitely the case in South Durban, with reports of a heavy storm following the sighting. Bluff residents said the storm, which included hail stones and flash flooding in some areas, was intense for a few minutes, but abated quickly.
