Norfolk County Council’s gritters will be back on the roads this afternoon following news that more snow is set to fall.
BBC weather has forecast heavy snow to fall across south Norfolk and north Suffolk from midnight tonight, with four to ten centimetres predicted.
Gritters will be carrying out two runs this afternoon and this evening to make sure the priority routes are well salted before the arrival of snow.
Forecasters are also warning that as the snow clears tomorrow morning it may turn to rain, followed by a sudden dip in temperatures as skies clear. Motorists are warned that there is therefore an increased risk that roads will be icy tomorrow morning, in spite of the efforts of the gritting crews.
County council gritters are preparing to work nonstop, however it takes up to three hours to treat the priority network of just over 2,000 miles.
The county council has also put farmers on alert around the county in case minor roads need clearing tomorrow morning, and Norwich City Council will have nine teams out on foot from 7am at known troublespots around Norwich.
With thousands of supporters expected from Luton for the sell-out FA Cup match against Norwich City at Carrow Road, special arrangements are being made to treat pedestrian routes to and from the football ground.
A slow thaw is expected to start on Saturday, becoming a rapid thaw as rain and gales arrive on Saturday night.
Temperatures on Sunday are expected to reach 8 or 9 degrees - the highest since the cold spell began more than two weeks ago.
In addition, the thaw is likely to be followed by an increase in the number of potholes caused by the big freeze. Potholes can be reported online at www.norfolk.gov.uk, and dangerous road defects needing urgent action can be reported on 0344 800 8020.
