The weather front from Siberia has caused significant snow fall across the region and, combined with freezing temperatures, is still causing travel chaos today with reports of crashes and snowdrifts blocking roads across the region.

A Norfolk police spokesman said there are reports of three to four feet snow drifts on many roads across the county.

Inspector Paul Rush, of Norfolk police, said: 'Please just because it's not snowing, it remains really challenging driving conditions. So please, expect the unexpected. There is drifting snow there is significant ice and at the minute we would urge people not to drive if they can avoid it. If you must drive, please, please drive to those conditions.'

Norfolk County Council said it had its gritters and ploughs out throughout the night but warned 'snow is blowing back onto roads and there are deep drifts in some areas'. It has all its 49 gritters, 80 farmers and excavators out to try and remove snow.

On public transport Sanders Coaches has said all its services are suspended, including school buses, due to drifting snow making roads impassable, and Konect are running a very limited service and no Park and Ride buses are running.
