NEW VIDEO + YOUR PICTURES: "Tornado" twister that hit Doncaster
New footage and photos have emerged of the "tornado" twister that was seen in the skies above Doncaster earlier this week.
Pictures and video clips of the ominous funnel cloud have been sent in by readers who saw the unusual weather phenomenon across huge chunks of South Yorkshire on Tuesday morning.
Yesterday we reported how workers at a Doncaster office had filmed the cloud on a mobile phone, expressing their disbelief in a crude but amusing commentary which went viral.
Now others who spotted the column spiralling from the clouds have supplied photos and video clips.
Amanda Inman Vickers filmed the cloud in this new video from Mexborough Highwoods while others reported seeing the cloud in Norton, South Kirkby and beyond.
Chris Tucka said he had seen the cloud twisting and added: "I've never seen one before. It was a lot bigger but I didn't get a photo quick enough."
Funnel clouds only become tornadoes when they touch the ground, becoming a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud.
They are often referred to as twisters and most have wind speeds less than 110 miles per hour and travel a few miles before dissipating.
However, the most extreme tornadoes can attain wind speeds of more than 300 miles per hour stretch more than two mile across, and stay on the ground for dozens of miles.
William Mostyn posted on Facebook: "Not a twister, was never anywhere near making contact with the ground still looked pretty awesome though."
