Met Éireann has issued an updated Status Yellow snow/ice warning for 11 counties for tonight, Wednesday, February 12.
In an update announced by the national meteorological office at 12:29pm this afternoon, the alert will be valid from 8:00pm this evening through to 10:00am tomorrow morning.
The warning will affect: Galway; Mayo; Sligo; Roscommon; Leitrim; Cavan; Monaghan; Donegal; Dublin; Louth; and Wicklow.
Some snow accumulations are possible before morning, mainly across the north and on higher ground elsewhere, it was added.
Meanwhile, for the country in general, Met Éireann says that many areas will be dry and bright this afternoon with spells of sunshine. However, there will be scattered showers which will become mainly confined to the north-west.
Another cold day is on the cards, but with less of a wind chill factor than recent days; highest temperatures of 4° to 8° are expected with it to be coldest in the north.
Later in the afternoon, rain will move into west and south-west counties, and southerly winds will begin to freshen.
It will become windy then too, as southerly winds increase fresh to strong, with gales developing on some southern coasts.
Whilst a clearance to showers will develop, it will remain wintry across Ulster until morning, with frost and ice in parts too.
Lowest temperatures of -1° to 4° coldest across the north and north-west. Winds will ease overnight, but will still be strong though near some coasts.
