Northamptonshire weather: Heavy snow warning
Road users across the East of England are being advised to check the latest weather forecast and road conditions before they travel.
The Highways Agency said it was expecting weather conditions on Sunday to become increasingly difficult.
Snow is falling in Northamptonshire and is expected to become heavier later.
"Road users are advised to take extra care when travelling due to the increased risk of adverse driving conditions," the agency said.
"Drivers are also advised to plan their journey before they set out, to check the forecast and road conditions."
Where conditions prove to be poor and a journey is unavoidable, drivers are asked to leave extra time or to consider delaying their journey if the weather becomes severe.
The Highways Agency is working closely with the Met Office to monitor weather conditions.
