SEVERE weather warnings have been issued for parts of Suffolk and Norfolk by the Met Office.

Up to five cm of snow is expected to fall overnight in some parts of the east.

Motorists are being advised to allow extra time for their journeys and to slow down, as black ice is expected and roads look set to be treacherous in places.

There is currently heavy traffic queuing on the A12 at Lowestoft, with the roads around Hopton and Corton described as being 'very busy' at the height of the evening rush hour.

With the Met Office warning locals of 'heavy snow and widespread icy roads' overnight, a spokesman said: 'Locally heavy snow showers will continue to affect south eastern England and East Anglia through the remainder of Wednesday afternoon and Wednesday night.

'There will be fresh accumulations of 2cm to 5cm of snow locally, although the snow showers will tend to ease later in the night leaving widespread icy stretches on untreated roads and pavements. Some drifting snow is likely in a strong north to north-easterly wind.

'The public are advised to take extra care and refer to the Highways Agency for further advice on road conditions on motorways and trunk roads,' the spokesman added.
