Snow and stormy weather has led to treacherous conditions and traffic chaos across Northern Ireland.
In Londonderry, schools were closed and bus services were suspended after heavy overnight snowfalls.
Snow made driving conditions difficult in Counties Tyrone, Fermanagh, Donegal and north Antrim.
Traffic came to a standstill on the Northland Road in Derry
The Met Office issued a severe weather warning. Motorists have been urged to take care on icy roads. There have been a number of minor collisions in Derry.
Several secondary schools and some rural primary schools in the area are shut.
The principal of St Mary's Primary School, Altinure, Tom O'Kane, said the snow was four to five inches thick.
"Usually somebody makes it in, but not one child has turned up," he said.
"Our teachers also have to make it across mountain roads from south Derry to get here.
"If even one child was injured, or one teacher... it's not worth it."
At the Glenshane pass, snow ploughs are waiting to ensure that the road remains clear.
It's understood that conditions will ease in the afternoon but more icy weather is expected later.
