This is the moment the Cornish shoreline was left covered in foam, just as Storm Bronagh swept the UK.

Lee James Palmer captured this photo as gusts of over 60mph battered the Duchy on Thursday.

The winds brought down trees and branches and sparked dozens of power cuts, from Truro to Bude.

It is not the first time sea foam has been spotted during wild weather in Cornwall.

Maureen Lord posted this incredible footage from St Agnes when Storm Aileen hit in 2017.

The dog you can see in the middle is called 'big pups' or 'little Boston'.

Maureen Lord's dog was up to his chin in sea foam when Storm Aileen hit Cornwall in 2017

Maureen's pet was all but covered by the sea foam, which gives you an idea of how deep it was.

She added that the pup was "totally bemused by it all" - and you can watch the footage below...

What causes sea foam?

America's National Ocean Service sums up the phenomenon as being when 'dissolved organic matter in the ocean is churned up'.

"If you scoop up some water from the ocean in a clear glass and look at it closely, you'll see that it's chock full of tiny particles.

"Seawater contains dissolved salts, proteins, fats, dead algae, detergents and other pollutants, and a bunch of other bits and pieces of organic and artificial matter.

"If you shake this glass of ocean water vigorously, small bubbles will form on the surface of the liquid.

"Sea foam forms in this way - but on a much grander scale - when the ocean is agitated by wind and waves.

"Each coastal region has differing conditions governing the formation of sea foams".
