Motorists are being urged to take extra care this morning due to potential road hazards following Storm Ciara.
Sleet is reported on many routes across the county, while surface and coastal flooding are major risks.
Donegal County Council has dispatched gritters to all main routes from 6am. However, motorists are being advised to assume that no road is ice-free.
With high wind gusts hitting Malin Head, there are reports of storm debris on roads around Killourt. Donegal County Council was unable to clear the debris last night due to the storm. Staff are set to wait until the storm passes before safely removing the debris.
Meanwhile, there are fears that more floods will affect the Lagg Road in Malin this Tuesday morning. Motorists are to avoid the area and use alternative routes. With the next High Tide due at 7.30am, there will be storm surge due to high winds, this will likely cause further flooding from approx 6.30am to 10.30am.
Two Status Yellow warnings for wind and snow/ice remain in place for Donegal until Tuesday night.
