100 days on from the Boxing Day floods many people affected are still struggling to rebuild their lives.
More than 2,000 homes and businesses were flooded in the deluge in December 2015.
One of the worst hit areas was Whalley, Ribble Valley, where the River Calder burst its banks.
Flood defences are being restored but there is no promise that they will hold in the future.
A severe flood warning remains in place for St Michael's on Wyre after more heavy rainfall overnight.
The Environment Agency says the area south of the River Wyre is at high risk of flooding due to raised river levels and pressure on temporary defences.
It says there is a significant chance the defences may not be able to cope with rising levels of water.
Environment Agency staff remain on site in the village.
Police say the situation poses a potential risk to life.
A533 Runcorn Road in Whitley is closed in both directions due to flooding at the A49 Tarporley Road (Tall Trees Junction).
A number of vehicles have become stuck in very deep water.
Rescue workers walked along a four-mile stretch of the M6 in Lancashire overnight to check on the condition of drivers.
A diabetic man was taken to Royal Blackburn Hospital, while an ambulance taking a female patient to Royal Preston Hospital had to be dug out of the snow by Bowland Pennine Mountain Rescue team.
ITV News Reporter Nick Thatcher reports:
Louise Jones was stuck on the M6 for hours overnight because of the heavy snow and she described it as the "scariest experience" she had had in 26 years of driving.
Mrs Jones, from Bootle, was travelling home from a restaurant in Wigan where she had been celebrating her father's 65th birthday when she got stuck on the motorway.
It took her more than five hours to travel the 20 miles home.
The Environment Agency has issued seven flood alerts in the North West.
