The alert advises people to “ask if your friends, family or neighbours need any support”.

They should also “stock up foods and medicines”, the warning adds, so there is no need to venture outdoors during the icy conditions.

Those who don’t go outside should ensure that their homes are warm enough, heated to at least 18C.

Colder than average homes can prove dangerous for vulnerable people, as low temperatures can raise the risk of strokes or heart attacks.
