Fresh snow shuts schools and Durham Tees Valley Airport
An airport has been closed and drivers have once again been warned of hazardous conditions in the Tees area.
Flights from Durham Tees Valley Airport have been suspended, with passengers advised to contact their airline.
Fresh snow falls have led to problems on many roads, including the A66 which will remain closed at Bowes until at least Thursday lunchtime.
More than 60 schools in Middlesbrough, Stockton, Hartlepool, Redcar and Cleveland and Darlington were closed.
There was a restricted timetable on the East Coast Mainline.
The Met Office issued a severe weather warning of widespread icy roads and snow for the North East.
Work to clear snow at Durham Tees Valley Airport will continue through Wednesday night and it is hoped it will reopen on Thursday.
