Heavy snowfall has left some roads in the west of the country impassable tonight.
There is a yellow state weather warning for snow, sleet, hail and ice for all counties in the Republic, along with Fermanagh and parts of Tyrone, Armagh and Down.
The notice will run until Sunday at noon.
During the night there will be a strong and widespread frost with some icy spots, as temperatures will drop between 0 and -4 ° C.
Tomorrow it will start very cold and icy, while the winter showers will continue throughout the morning with possible accumulations.
The Bantry / Drimoleague road (R586) is closed west of Drimoleague after a serious car collision.
Kerry County Council says the Conor Pass northeast of Dingle is impassable, as are sections of the N59 near Clifden, Co Galway.
Gardaí advises avoiding the Wicklow Gap and the Sally Gap due to the icy conditions.
Drivers are reminded that it can take up to 10 times longer to stop a vehicle on icy roads. Anyone driving in icy conditions should make sure to slow down and stay well behind whoever is in front of them.
Andrew Doran-Sherlock, Met Éireann forecaster, says snow may not stay everywhere, but people everywhere will have to watch the ice.
“Even where there are not very large accumulations or where there is more dust, with low temperatures there will be icy conditions on the roads and highways, so people will have to be careful.”
Doran-Sherlock said winter conditions appear to continue well into some parts.
“There will be sleet, snow and hail in most areas with developing accumulations.
“By tomorrow morning it will reach the east and sink into the Irish Sea.
“But this is associated with a low-pressure system. It will stagnate in the Irish Sea and end, so there will be a little more that will reach the eastern coastal counties tomorrow morning, possibly in the afternoon and in the evening. “
#Sneachta and #snow tended to Twitter as people across the country shared snapshots of the snowfall, scenic landscapes and children playing.
