Weird clouds formed over Lancashire and Mersyside on Sunday. People have been sending in their pics to the BBC. This one is from Chloe Mould, from Ormskirk, Lancashire.
The clouds are formed by swirling winds, and are like tornadoes. Courtney Reid sent this shot of one forming over Hesketh Bank, Preston.
Joe White, from Ormskirk in Lancashire, sent this one in. He said: "Me and my family got a great display of the clouds from our attic."
Stan White was at the Martin Mere Wetland Centre in Burscough, Lancashire when the weather changed. He said: "Strong winds from the funnel frightened birds away."
Paul Bolton said: "My wife and I saw this from our flat in Birkdale, Southport on Sunday afternoon."
