Motorists in Cornwall are being warned to prepare for snow and ice on many of the county's roads.
The Met Office has warned that snow showers are expected to continue during Friday night with widespread ice forming on untreated surfaces.
Paul Allen from Cornwall Council said 25 gritters would grit the primary roads twice overnight
He said: "Check the forecast, make sure you're prepared, if out driving reduce speeds."
He added: "Further snow showers are forecast right through the night and into tomorrow morning and as temperatures drop any untreated roads are going to be very icy."
Heavy snow began falling on Friday in the west of the county affecting areas including Bodmin, Pensilva and Saltash.
The BBC travel website reported that some roads were slippery because of compacted snow through Bodmin Town, the A3083 Helston to Lizard road and the A388 between Launceston and Callington.
First Bus said the number 25 route between St Austell and Fowey was unable to serve St Mary's and Roselyn Road but that all other services were operating with care and some delays.
Early flights between Plymouth and Newquay had to be cancelled and nearly 20 schools were closed bringing an early start to the Christmas holidays for many students.
