People across the county are being warned to take care when travelling 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.
The flood warning at Billing Aquadrome near Northampton is likely to remain in place for several days.
Boaters are also being warned that the River Nene currently has Strong Stream Advice in place, making navigation inadvisable.
Although rivers are likely to remain high for several days, on current forecasts the Environment Agency hopes there will be sufficient time for levels to recede between bands of rain.
Andy Wilkinson form 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.”
