The arrival of mammatus clouds over west Lancashire on Sunday afternoon gave residents a strange sense of foreboding.
Local resident Stephen Cheatley described the scene over Blackpool as "apocalyptic" on X (formerly Twitter).

The bizarre cloud formation, whilst looking somewhat scary, is more common than you may think and was linked to the arrival of cumulonimbus clouds on the Fylde coast.
The air turbulence within the cumulonimbus clouds can cause plumes of colder air to emerge from the base of the cloud. This then forms the bulges or pouches that give the cloud their name.
The name "mammatus" is actually derived from the Latin "mamma", which means "udders" or "breasts".

Their appearance was still enough to make locals uneasy, with Esther Parkinson on X (formerly Twitter) saying the skies "looked a bit like Armageddon".
Mammatus clouds can often indicate that heavy rain, hail, or thunder and lightning are nearby.
Their appearance is always much more dramatic around sunrise or sunset, as the low angle of the sun captures their unusual shape.
