Terry Douris, Cabinet Member for Highways at Hertfordshire County Council, said: “The forecast tells us temperatures are predicted to drop by 10 degrees with a chance of wintry showers falling on Hertfordshire over the weekend.
"Because the weather’s been so mild it’s unlikely any snow we might have will settle, but we want to make sure there’s no risk of surface water freezing on our roads. “Salt is the best material we have to treat ice and snow, but it's by no means perfect, so we recommend that residents take great care when driving or walking in ice or snow."
