Elsewhere, firefighters were called to rescue 200 sheep trapped when a barn roof caved in under the weight of snow near Alnwick, Northumberland.
Rescuers from Northumberland Fire and Rescue Service and Northumbria Police dug their way through deep snow to clear a path to the trapped animals at Dyke Farm, Newton-on-the-Moor, near Alnwick.
Alex Bennett, acting chief fire officer for the fire and rescue service, said: "As the severe winter weather continues into week two the amount of snow building up is putting farm buildings at risk.
"We would advise farmers to regularly inspect their sheds containing animals.
"People should not get on to shed roofs without the correct safety equipment but where possible evacuate animals until the snow can be removed."
Hazardous conditions were also reported on a number of roads including the A68, A69 and A1 in Northumberland.
Passengers due to travel from the airport were advised to contact their airlines if they had any concerns and be prepared for disruption to their flights.
