The Met Office and Government health bosses are warning all regions of England over "severe winter weather" this week.
A Level 2 cold weather alert, which means people should be "alert and ready", is in place from 6pm on Sunday, February 5, to 6pm on Tuesday, February 7.
The Met Office said there is "60% probability of severe cold weather", and that this could "increase the health risks to vulnerable patients and disrupt the delivery of services".
