Motorists are being warned of treacherous driving conditions in Huntingdonshire tomorrow (Friday).
The Met Office has issued a yellow warning of ice from 12.05am to 9am.
A forecaster has said: "Surface temperatures will fall to around or just below freezing late on Thursday night into Friday morning across parts of England and Wales. With a lot of standing water present in many areas from the recent wet weather and flooding icy stretches are expected to form, particularly on untreated surfaces.
"The public should be aware of the potential for disruption to travel on the roads.
"With clearing skies and easing winds overnight Thursday temperatures will fall with surface temperatures dropping below freezing in places late on Thursday night and early on Friday morning. Large amounts of standing water remain on the ground in many places following recent wet weather and flooding. This will result in icy stretches forming in places, despite only small amounts of rainfall on Thursday."
