Northumberland has been warned to expect icy conditions on the roads into tomorrow as snow is already causing disruption.
The Met Office has extended its yellow warning of ice throughout Northumberland tonight. It now applies to tomorrow morning.
The alert says: "Icy patches are expected on untreated surfaces from Friday evening onwards into early Saturday morning, particularly across eastern, southern and central Scotland. Please be aware that this could lead to some difficult driving conditions."
The chief forecaster added: "A cold airmass covers northern Britain. Under clear skies, rapidly falling temperatures early this evening will lead to the formation of icy patches on untreated surfaces, especially where rain, sleet or snow has fallen today or where the is seepage of water as a consequence of recent wet weather. Further outbreaks of snow, mainly over hills, are likely to return to parts of northern England and during the early hours of Saturday."
Sleet and snow, as forecast yesterday, will continue on the western side of Northumberland today, before clearing east into the North Sea by evening. Some of this will be heavy and could bring accumulations of 5-10cm on ground above 200 to 300 metres, with 1-3cm settling to low levels in places.
The Met Office says: "Please be aware of some difficult driving conditions and the risk of travel disruption."
Northumbria Police have also reminded the public to drive carefully as adverse weather hits our region.
Officers said: "Parts of rural Northumberland are already experiencing heavy snow which could lead to potentially dangerous road conditions. Drivers travelling on the A696 Otterburn Road should be particularly careful. There is snow on the road but it is 'passable with extreme care'.
"There are also pockets of heavy snow along the A68 between Redesdale and Carter Bar on the Scottish border. The A697 is also slippery and our officers will be in the areas affected to assist if required. Motorists should drive responsibly and keep their speed down as stretches of both roads will be slippery."
