County Durham funnel cloud footage causes stir on social media
What looked like a tornado, but was actually a funnel cloud, has caused a stir in County Durham.
Dozens of people captured the sighting on Friday, with many on social media speculating the weather phenomenon was a tornado.
Funnel clouds form around localised areas of intensely low pressure, in the same way as tornadoes. But they are only classed as a tornado if they touch the ground.
