Thousands of homes across Devon and Cornwall are without power as Storm Eunice strike.
It comes after the Met Office issued a red weather warning a rare second code red warning as the storm covers London, the southeast and east of England.
BBC Weather said it “could well be one of the worst storms in three decades” as forecasters predict gusts of up to 90mph.
This is a breaking story. More to follow.
There have also been warning of danger to life.
Western Power is now scrambling to help more than 8,000 homes in Cornwall and nearly 7,000 homes in Devon.
Devon and Cornwall County Councils have advised people against unnecessary travel and many schools across the region are closed.
Cornwall councillor Martin Alvey said: “We have got past the first concern which was the high spring tide along our north coast.
“Those communities that we were anticipating may be badly impacted seemed to have got away fairly lightly although certainly there may have been some minor incidents still to come into us.”
And the Royal National Lifeboat Institution (RNLI) have echoed those fears.
RNLI lifeguard Tom Bolt said: “I would not recommend people go on cliff tops and get close to the sea, always watch from the distance.
“Please do not hesitate to call 999 or ring the coastguard if anyone is in danger, however, people should not enter the water in the first place.”
Cornwall has declared a “major incident” until 12pm today.
The Met Office has issued a “stay indoors” warning with Storm Eunice set to move in with winds reaching 100mph.
Tens of thousands of households of households have already suffered power outages after Storm Dudley pummelled the UK and Ireland with winds of more than 80mph.
And now millions more could be impacted.
Helicopters have been put on stand-by to help speed up repairs to areas which see their power supplies cut.
Western Power has put in place a number of preparations to allow it to quickly restore power.
The helicopters are available to fly and identify badly affected areas and quickly get people back online.
Operations Director Graham Halladay said: “Preparations are in place so that, whatever the weather, we can work to restore power supplies quickly and safely if they are disrupted.”
