People in Devon are being urged to take extra care when travelling later today and overnight, with widespread snow forecast.

Localised showers are expected to turn wintry from around 6pm tonight onwards, with The Met Office issuing a yellow alert for the risk of snow, particularly on higher ground and in the north of the county. However, snow may fall across any part of Devon.

Devon County Council, the Highways Agency, and Devon and Cornwall Police are advising motorists to check the weather forecast and road conditions before setting out.

The authorities have mobilised teams across the county, gearing up for the potential of snow. Vehicles have been deployed at Haldon Hill, Telegraph Hill and the North Devon Link Road to monitor the situation, and are prepared to step up their response should conditions become more severe.

Devon County Council is warning that conditions on the local highway network will be challenging with a mix of rain, sleet and possibly up to 5cm of snow on higher ground, including Haldon Hill and Telegraph Hill.

Devon County Council gritters are treating around 1,700 miles of the precautionary salting network across the county from around 3pm and again overnight. Road surface temperatures are expected to drop as low as -2.5 C overnight which could mean that ice could be a problem tomorrow morning, particularly on untreated roads.

The Highways Agency, which is responsible for motorways and major A-roads, is treating the 170 miles of the strategic road network in the county.

Councillor Stuart Hughes, Devon County Council Cabinet Member for Highway Management, said: “The potential combination of rain, sleet and snow makes conditions extremely challenging on our roads. The rain can wash the salt from the roads, so our highways teams are working to ensure that travelling conditions do not become hazardous, particularly while people are travelling this evening and tomorrow morning. I would urge everyone to be alert to the conditions, plan your journey accordingly – particularly if it isn’t essential – and be prepared for the possibility of disruption, so allow extra travel time.”

Highways Agency Emergency Planning Manager, Rob Llewellyn, said: “The Highways Agency and its partners are well prepared for severe weather at Haldon Hill but we would remind drivers they also need to check the latest weather and traffic reports before setting out and decide if their journey is absolutely necessary if conditions worsen.”

Motorists are reminded 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 possibly be helped through the cold spell; • Listen to local radio for updates on current weather conditions.
