Police have warned motorists to only travel when necessary today as heavy snow and sub-zero conditions continue to blight the region’s transport system.

A Met Office yellow warning for snow will remain in place until 11.55pm tonight across the region. It was originally due to end at 11am. Several roads were left impassable following heavy snowfall overnight, with up to five inches reported in some areas. Here is the latest weather forecast.

Travellers reported major traffic delays and stranded cars on the A14, A12, and urban and rural roads. East Anglia was the worst-hit region in the country. Temperatures fell to at least -3C overnight.

Suffolk police were called to around 130 weather-related emergency and non-emergency incidents between 7am and 11am today.

Greater Anglia was forced to cancel or delay over 100 services this morning. Shortly after 11am, it announced a reduced service will operate between:

Meanwhile, Ipswich Buses have decided to suspend all services until further notice due to the dangerous road conditions.

Chief Inspector Matt Rose, of Suffolk Constabulary’s ‘Suffolk Contact and Control Room, said: “Only get behind the wheel if it is completely necessary and, please, if you do travel make sure you make the necessary provisions for your journey and make sure your vehicle is prepared for the journey ahead.

“Our priority is those who are already stuck or have been involved in an RTC. Please bear with us, we have to take the same precautions you do and it may take as slightly longer to get to you.

“My final appeal is for you to look after each other. If you have elderly or vulnerable relatives or neighbours, make sure they are ok and have everything they need.”
