"The county council's gritters will be treating many of the main routes across the county overnight, with a widespread heavy frost and icy conditions expected tomorrow morning.
"Untreated surfaces could be hazardous."
Please drive carefully this morning, numerous accidents already. Not just snow, but hidden ice patches too. Please slow down and be alert.— DevonCornwall Police (@DC_Police) January 30, 2019
"Haldon and Telegraph Hills may see a small amount of snow.
The picture is still mixed for tomorrow but there's a high chance of heavy snow forecast in some parts of Somerset - much of Devon is expecting heavy rain according to forecasters.
Councillor Stuart Hughes, Devon County Council Cabinet Member for Highway Management, said: "We would urge everyone to be prepared.
"Our advice is to plan your journey, keep an eye on the weather forecast and please take extra care when travelling."

The County Council is reminding people of the following advice:
- Avoid overnight travel unless absolutely essential as roads will always be more hazardous at night with less traffic and colder temperatures;
- Never assume a road has been salted. Remember that showers or rain will wash salt off roads leaving them prone to ice, and in extreme cold even salting will not stop ice from forming;
- Allow additional time for your journey and reduce your speed;
- Drive with care and according to the conditions;
- If you have vulnerable or elderly neighbours, think about how they could be helped through the cold spell;
- Try to maintain indoor temperatures to at least 18C, particularly if you are not mobile, have long term illness or are 65 or over;
- Listen to local radio for updates on current weather conditions and ensure you are stocked with food and medications.
Dusting of snow in higher ground in the north of the county, salt applied to the main routes but please take care. #drivesafelyplease— Travel Dorset (@TravelDorset) January 30, 2019
