Bizarre clouds that looked like flying jellyfish have left onlookers stunned as Storm Dudley battered the country.
Brian Morrison, from Glasgow, Scotland, filmed the bulbous formation, which is known as Mammatus.
The cloud formation is a rare and spectacular phenomenon which is the result of a process best described as reverse direction conviction.
The clouds are an indicator of severe weather conditions.
During a thunderstorm, warm moist updrafts rise to the top of the troposphere where the temperatures level off, creating the pendulous clouds.
Brian filmed the video at around 4:30pm yesterday in his hometown.
Storm Dudley battered the country yesterday as strong winds and rain ripped trees from their roots and power outages in parts of the country.

Winds speeds of up to 80mph were recorded in parts of the country with an Amber alert issued by the Met Office until midnight.
As the clouds appeared, one local joked: "Oh my God. Giant jellyfish aliens...Run!"
Another onlooker, Jen Edwards, said the clouds were “really cool to see, but also a bit creepy."

Another said: "Ah man you were lucky to see those, I am slightly jealous.
"They often occur when thunderclouds form."
Sue Smith joked: "Sky dumplings."
Storm Dudley saw ferocious winds of up to 80mph strike, as many were left without power in the worst affected regions as an amber weather warning was issued.

This morning, yellow wind and ice warnings remain in place from the northern tip of Scotland to as far south as Birmingham.
From Friday, Storm Eunice is predicted to batter the south and an amber weather warning is in place for the region, along with yellow warnings further north for wind and snow.
There have been stark warnings that it could be one of the worst tempests in 30 years, with winds of up to 100mph possible in parts of the UK.
