Met Eireann is warning motorists to take extra care this weekend as wintry weather arrives in Donegal.
Snow and hail are forecast to fall on Friday night and Saturday, leading to localised accumulations. Snow will compact into ice in some areas and cause hazardous driving conditions.
Temperatures will dip to between 3 and 0 degrees Celsius tonight and snow will lie on high ground, according to Met Eireann.
Council gritters will be out on all main routes from 8pm, but motorists are advised to assume that no road is ice free.
There is also a wind warning in place for Donegal tonight and tomorrow, with strong westerly winds reaching mean speeds 50 to 65 km/h gusting to 90 to 110 km/h. There is a risk of stronger winds at the Donegal coasts.
The wind warning takes effect from 5pm Friday to 5pm Saturday.
The snow/ice warning is in place from midnight Friday until midnight on Saturday.
Frequent showers during the day on Saturday will be “heavy at times and wintry on hills,” said Met Eireann.
Temperatures are forecast to drop to lows of -3C and highs of +1C on Saturday night, with more snow possible over high ground.
