Residents of Billing Aquadrome may not be able to return to their homes until next week as a flood warning is likely to be in place for several days, the Environment Agency has said.
About 650 people were evacuated from the caravan park yesterday and 60 people were forced to spend the night at Lings Forum Leisure Centre.
The Environment Agency has advised people across the county to take care when travelling today and into the weekend as standing water and high river levels could remain for several days.
Forecasts are currently for more bands of rain to sweep across Northamptonshire over the next few days as the unsettled weather continues.
People are being advised to avoid driving or walking through flood or standing water and to check they are signed-up for flood warnings.
Boaters are also being warned that River Nene currently has Strong Stream Advice in place, making navigation inadvisable.
The horse racing at Towcester Racecourse on Sunday has been abandoned due to a flooded course.
Andy Wilkinson, spokesman for the Environment Agency, said: “Although we’re hoping river levels don’t get any higher, it does all depend on the weather. We’ll be monitoring this closely over the next few days and issuing warnings as necessary.
“People need to keep an eye on local conditions and make sure they are signed-up to receive flood warnings.”
