Commuters across Donegal have been warned to take extra care with falls of sleet and snow overnight.
While most roads are passable, motorists have been advised to slow down.
And the forecast is for more sleet and snow and freezing conditions in the coming days.
According to the national forecaster, showers of snow are expected this morning.
While accumulations of snow of up to 3cm are possible on a local level, it is likely to gather mainly on hills and mountains in the West.
Met Eireann forecaster Jean Byrne told RTE Radio One’s Morning Ireland that it is set to be very cold over the next few days.
“There will be frost and a risk of wintry showers.
“Today will be very cold with frost, ice and snow,” she said.
“During the day, these wintry showers will turn into rain, hail and sleet.
