Heavy snow has hit parts of the North East, prompting fears of travel chaos.
The Met Office has upgraded its "cold weather action" warning to level three - one underneath a national emergency - for all of England. They are urging social and healthcare services to concentrate on at high-risk groups.
It said: "This weather could increase the health risks to vulnerable patients and disrupt the delivery of services."
A number of yellow and amber warnings are also in place across the country to highlight the hazardous conditions and likelihood of disruption to travel services caused by the ice, snow and freezing temperatures.
