Untreated surfaces could be hazardous. Councillor Stuart Hughes, Devon County Council cabinet member for highway management, said: There is a risk of snow this week, with the first spell of wintry showers expected from tomorrow afternoon, so 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.
