More snow is expected to hit Donegal, Cavan and Monaghan, as drivers are being warned to slow down to avoid accidents after a fatal collision and series of mini-crashes.

Meanwhile, the AA Roadwatch are asking drivers to slow down and increase stopping distances in areas of ice and frost.
Conor Faughnan, AA director of consumer affairs said he urged caution for all road users, including pedestrians at risk on icy pavements.
"Unfortunately there was a fatality on the M7 on Tuesday night near Nenagh on the road from Dublin to Limerick and the motorway was closed," he said. "And there was another significant crash on the motorway near Galway just east of the city on Tuesday night.
"We won't know what caused these crashes for some time but we must remind drivers in these conditions to slow down and increase their stopping distances.
"Black ice is a real danger. It isn't visible to the eye, so if you're driving too fast for the road conditions, you could skid out of control."
Mr Faughnan called on motorway users to drive well below the 120kmh maximum speed limit and said it was vital for drivers to increase stopping distances.
