Government health chiefs and the Met Office have issued an update as a "severe" cold weather alert has been extended.
The UK Health Security Agency (UKHSA) says the level 3 alert is now in place until 9am on Thursday, March 16, for the North East and North West of England, as well as Yorkshire and the Humber. A level 2 alert is in place for the West Midlands, East Midlands and East of England for the same period.
There is a "90% chance of severe cold weather/icy conditions/heavy snow" between 3pm on Monday and 9am on Thursday, according to the Met Office.

Part of its cold weather alert update reads: "Colder air will spread southwards Monday evening and overnight behind a band of rain, which will turn to snow in places, particularly in northern England. Temperatures will then fall, with widespread frost and ice forming by Tuesday morning.
"Tuesday will see cold conditions with hail, sleet and snow showers, and another cold night will follow. On Wednesday milder air will spread in from the Atlantic again, with a brief spell of snow on its leading edge turning quickly to rain."
People are being urged to "check in on the wellbeing of those most vulnerable to the cold". Dr Agostinho Sousa, Head of Extreme Events and Health Protection at UKHSA, said: "Cold weather can have a serious impact on health, particularly older people and those with pre-existing health conditions, as it increases the risks of heart attacks, strokes and chest infections.
"If you have a pre-existing medical condition or are over the age of 65, it is important to try and heat your home to at least 18C if you can."
