Shop owners in Appleby-in-Westmorland - the first town to be affected by the floods at the weekend - have been speaking of their devastation.
Catherine Hoggins was among them. She had only opened Appleby Barber Shop in Bridge Street last Monday - having relocated from the market arcade, which has escaped much of the damage.
Quote Message: What can you say? Self employed, three kids, single mum, three weeks before Christmas, what do you do?

Jackie Kilpatrick, 58, who runs interior furnishings firm Jak & Co - a new business venture which has only been open four weeks - said many businesses would not be reopening until February.
Quote Message: I'm devastated. Everybody has been affected but I will say there has been an amazing community spirit.

Labour leader Jeremy Corbyn - speaking at the Trade Unions for Energy Democracy meeting in Paris - has accused the government of failing to deliver on its promises when it comes to dealing with flooding.
Quote Message: Last year, the prime minister of Britain promised that 'money is no object' in dealing with flooding, itself a consequence of the destruction of our environment.
