Flurries of snow across Norfolk have caused problems for motorists today with further showers expected throughout the day. Although Norfolk is expected to escape the worst of the wintery weather, temperatures in Norwich are predicted to stay at freezing and dip to -2 or -3 tonight - although not the -10 which was recorded at Marham today.

Forecasters said Hampshire, Oxfordshire, West Berkshire, Surrey and Buckinghamshire would see 'exceptionally heavy snowfall' as the blizzards moved south but this region would not escape altogether.

Drivers were urged to take extra care as temperatures are unlikely to get above zero in many places - and hit -10 at Marham overnight.

The Met Office has issued a warning of 2-5cms of snow in Norfolk and Suffolk today and is advising drivers to take extra care.

A spokesman said: 'Snowfall this morning will give accumulations of 2 to 5cm quite widely. Widespread icy roads and pavements are also expected. The combination of snow and ice means widespread disruption to traffic is expected.

'The public are advised to take extra care and refer to the Highways Agency for further advice regarding traffic disruption on motorways and trunk roads.'

Delays are already being reported on many roads and there are problems on the trains with National Express East Anglia warning of a revised timetable and First Capital Connect running an emergency timetable.

John Law, forecaster at Weatherquest which is based at the University of East Anglia, said: 'It is not nearly as bad for us as in other areas. It is going to be cloudy today with some snow showers moving in from the north and the west which will leave a covering in many places. There is also more on the way overnight and tomorrow.

'We had a report of -10 at Marham which was the coldest place in Norfolk but it is more likely to be -2 or -3 tonight which will lead to a crust of ice which could cause problems for drivers.'

The team of gritters trying to keep the county's roads moving were out in force again overnight with a fresh delivery of salt arriving by boat at King's Lynn yesterday.

However, the heavy snow is still causing delays and cancellations to bus and train services in the west of the county.

Norfolk Green buses are currently not stopping in Burnham Overy Staithe on the Coasthopper, Shouldham Thorpe on the 39 or Harpley or Great Massingham on the 48.

The 63 between Wisbech and King's Lynn is running again because of improved road conditions.

Trains are running on an emergency timetable from Lynn station. One train leaves at 50 minutes past each hour between King's Lynn and Royston, calling at all stations to Royston; there are two trains an hour between Cambridge and King's Cross, leaving Cambridge at 58 and 28 minutes past each hour.

The Isle College, Wisbech Campus, of the College of West Anglia is still closed and this morning there were delays on the roads leading in an out of Lynn, including long delays on the A148.

East Midlands Trains is currently running a normal service on all of its key routes.

A spokesman said: 'We are currently running a normal train service on all of our key routes, and are committed to ensuring this continues throughout the day. The majority of our services are running punctually, and yesterday we successfully ran more than 97pc of our London services on time, proving that we can run a reliable and punctual service despite the severe weather conditions.

'However, we understand that many of our passengers may have difficulty reaching the station to catch their train, and arrangements have been put in place for those passengers.'

There has been some heavy snow this morning in Lowestoft, with a covering on the town's roads and paths and it is bitterly cold.
