It runs from midnight until 7am on Monday, with warnings also in place for counties on the Republic of Ireland's west coast. Gusts of up to 80mph are expected.

There will be heavy rain on Sunday and Monday, the Met Office said, adding that "flying debris" could put people's lives in danger.

Franklin will bring "gale force westerly winds with severe and damaging gusts", Met Eireann said, "combined with very high seas".

This is the first time the Met Office has had three named storms within a week since the current system was introduced, meteorologist Becky Mitchell said.

"We had Dudley on Wednesday, Eunice on Friday and Franklin today," she pointed out.

The reason for the sequence is because "we've got a really active jet stream, which is why we're seeing so many storms track right towards the UK", Ms Mitchell added.

The damage from Franklin is not expected to be "as severe" as that caused by Eunice because the strongest winds will be confined to the coast, Ms Mitchell said.

But conditions could still be "treacherous" and up to 80mm of rain may fall in northwest England.

Franklin's arrival comes just days after widespread damage caused by Storm Eunice.

Power companies have revealed that a record 1.4 million homes were affected by cuts on Friday during the worst of Eunice.

The Energy Networks Association (ENA) said 83,000 people were still without power on Sunday morning.

Ross Easton, from the ENA, said 8,000 engineers are working to reconnect customers but many homes will still be without power during the week.

Scottish and Southern Electricity Networks said it was making "good progress reconnecting customers".

As of 11am on Sunday, it said it had restored power to more than 164,000 homes, with 18,000 still awaiting reconnection.

Network operators can be contacted free on 105 in England, Scotland and Wales, while the number in Northern Ireland is 03457 643 643.

Western Power Distribution said the South West saw the most widespread power cut ever recorded.

The company said power had been restored to nearly 461,000 of its customers, and work was continuing to restore supply to the remaining 60,000.

Operations director Graham Halladay said: "Storm Eunice has brought some of the worst conditions we have ever seen - it is truly unprecedented.

"But I would like to reassure customers that we are working round the clock to get the lights back on as quickly as we can safely do so."

The storm saw a record wind gust of 122mph at The Needles on the Isle of Wight on Friday, and at least four people were killed in the UK and Ireland.

There are two more Met Office weather warnings in place:

• A yellow warning for rain covering Cumbria, Lancashire, and West Yorkshire until 6pm on Sunday, with a chance of flooding and difficult driving conditions

• A yellow warning for wind across most of England and Wales from midday on Sunday until 1pm on Monday, with damage and disruption possible

Sunday could see gales of up to 70mph in parts of England - the same speed recorded at Heathrow on Friday as thousands of people tuned in to YouTube channel Big Jet TV to see planes trying to land.

Speaking on Saturday, Met Office meteorologist Greg Dewhurst said: "We will see a slight easing in the wind over the evening time tonight, but it's not long before they pick up again tomorrow to lead to another windy day across the UK.

"This will have an impact on the clearing up process over the course of the day."

Rail disruption is also expected to continue on Sunday:

• Great Western Railway trains will have a 50mph speed restriction resulting in a reduced service with delays and cancellations

• CrossCountry routes will be open, except for trains between Bristol and Exeter

• Southern Rail: no trains between Redhill and Tonbridge; no trains between Dorking and London Victoria; no trains between Ore and Ashford until at least 8am; no trains between Horsham and Epsom via Dorking until at least 8am; trains will not call at Battersea Park in the direction of Sutton/West Croydon; trains will not call at Christ's Hospital; trains will not call at Hever or Cowden until 8am; rail replacement buses will continue between Three Bridges and Brighton/Lewes.

• Southeastern Railway said trains between Hastings and Tunbridge Wells would be suspended until at least midday, while the Canterbury East line will also be partly suspended until at least midday

• Great Northern said there would be no trains between Stevenage and Hertford North - and a reduced service between London Kings Cross, Cambridge, Ely, Kings Lynn.
