The Met Office has issued a Level 3 (Severe Weather Action) Cold Weather Warning for the period between 0900 on Thursday 14th January and 1200 on Tuesday 19th January in parts of England.
What does the cold weather warning mean?
This is issued when the weather described in Level 2 actually happens. This means that a mean temperature of 2°C is predicted for at least 48 hours and/or widespread ice and heavy snow is happening now, and is expected to impact on people's health and on health services.
Although there are usually fewer days at these low temperatures, the risk of negative health impacts increases as the temperature falls. Aside from cold temperatures, snow and ice are associated with an increase in injuries and severe disruption to services.
You should refer to the Public Health England Cold Weather Plan and the "Keep Warm, Keep Well" information leaflet for further information, links as follows:
