A severe weather warning has been issued for south-west Hertfordshire after temperatures plummeted over the weekend.

Public Health England (PHE) issued a Level 3 Cold Weather Alert for the region due to the bitterly cold conditions.

The weather warning is issued when severe weather is occurring, when average temperatures have dropped to 2C or below and widespread ice and heavy snow is present.

Doctor Angie Bone, of PHE, said: “Many places are going to feel really cold for the next few days, which may be a bit of a shock after our recent milder weather, so it’s really important people take extra care when out and about.

“It’s worth remembering that while most outdoor slips, trips and falls in weather like this are of those who are of working age, accidents can happen to anyone.

“If you’re staying indoors have plenty of warm food and drinks to stay warm. Try to maintain indoor temperatures to at least 18°C, particularly if you are not mobile, have a long term illness or are over 65, and check weather forecasts and plan your day around them.

“Although most of our advice on keeping warm and well in cold weather may seem like common sense, it’s important to remember that cold kills, even in places where the temperatures aren’t at their lowest.”

Forecasters said the cold blast is expected to continue into the early part of this week with temperatures dropping to -3C tonight.
