The Met Office has forecast that the current spell of cold weather is likely to affect all regions of England and will last until 9am on Friday January 1.
All areas are likely to see cold, overnight conditions, with a risk of icy patches and overnight frosts along with wintry showers which could produce some snow down to low levels. Temperatures in some areas will then remain in low single figures during the daytime.
Dr Owen Landeg, Principal Environmental Public Health Scientist at PHE, said:
Looking out for others at this time is really important so remember to check on frail or older neighbours or relatives, especially those living alone or who have serious illnesses, and make sure they have everything they need. Remember to follow the COVID-19 social distancing and restrictions in place in your area.

This year PHE has supplemented the Cold Weather Plan for England with useful resources and advice on the concurrent risks of cold weather and COVID-19 and how to keep warm and keep well this winter.
