Gritters will be out treating North Devons roads with temperatures set to plummet tonight (Thursday). A cold weather warning has been issued for the region with the possibility of up to 2cm of snow over Exmoor this evening. Devon County Council is advising people to take extreme care if travelling overnight and tomorrow morning, particularly on untreated roads. Councillor Stuart Hughes, DCC cabinet member for Highway Management, said: Weve had a relatively mild winter so far, so it may come as a shock to some people with temperatures dropping to their lowest of the season so far. I would urge everyone to take extra care overnight and tomorrow, plan ahead and reduce your speed. There are still a lot of damp roads around which means that ice could be a hazard, particularly on untreated minor roads. Its possible for ice to form on treated roads. Every effort is being made to keep our highways as clear as possible in order to keep Devon moving. Over the past few days the countys highways teams have been responding to flood and storm clear up, and addressing blocked drains to get our main salting network in the best condition possible. Road surface temperatures could drop to -5C on Saturday evening and freezing conditions are expected to continue into next week.
