SUB-ZERO overnight temperatures are expected to continue throughout the week and Herts County Council is urging residents to take extra care when out and about.

With icy conditions exacerbated by thawing snow during the day and overnight temperatures that could reach as low as minus seven, Stuart Pile, cabinet member for highways and transport, said that while the council is continuing to salt main roads and clear pavements, caution was still needed.

He said: “If you have to drive, please leave plenty of room between you and the vehicle in front, steer and brake very gently and reduce your overall speed. Pedestrians are also asked to take a great deal of care on pavements and when crossing the road.”

Anyone with vulnerable family members or neighbours is also being asked to check on them as a precaution and contact the county’s Keep Well, Stay Warm campaign if they have any concerns or need extra support via the HertsHelp number on 0300 123 4044 or visit www.hertsdirect.org/hertshelp

Residents have also been reminded by the county’s Fire and Rescue service that they should not venture onto frozen water at any time. Pet owners are also advised to avoid walking their pets near frozen water or make sure dogs are kept on leads.
