Storm Dudley's weird and wonderful clouds

Mammatus clouds formed over parts of Scotland during Storm Dudley on Wednesday evening.

According to the Met Office, the unusual clouds with their pouches and bulges form in association with huge and unstable cumulonimbus clouds, which often bring heavy rain.

Mammatus comes from the Latin mamma which translates to "udder" or "breast".
