The Met Office has upgraded the snow warning in parts of the Anglia region from yellow to amber.
The main risk is on Tuesday morning in the north west and south east corners of the Anglia region though Northamptonshire, north Cambridgeshire and south east Essex.
A yellow weather warning is in force for most of the Anglia region from the early hours of Monday until Thursday
What an amber weather warning means
"There is an increased likelihood of bad weather affecting you, which could potentially disrupt your plans and possibly cause travel delays, road and rail closures, interruption to power and the potential risk to life and property.
"Amber means you need to be prepared to change your plans and protect you, your family and community from the impacts of the severe weather based on the forecast from the Met Office."
