The satellite image below shows the immense storm that is on its way to the coast of Cornwall.
The county is bracing itself for the ferocious weather system about to hit the coast.
The gale-force winds and heavy rain could cause serious damage to communities still recovering from an unprecedented succession of heavy weather.
The storm building up in the Atlantic is expected to bring with it some of the biggest waves ever seen in the UK.
The Met Office has issued weather warnings for wind and rain for the next two days and the RNLI is warning people to stay away from the coast.
Will Stephens, RNLI Coastal Safety Staff Officer, said: "With more stormy weather forecast, we're asking people to take extra care if they're going down to the coast. Rough seas and extreme weather might look exciting, but getting too close can be risky.
“So respect the water and, in particular, avoid exposed places where big waves could sweep you off your feet."
Sur forecasting website Magic Seaweed has predicted a swell height of up to 42ft (12m) at Sennen near Land’s End.
The storm is expected to come into Cornwall later tonight and last through Saturday.
