Schools and colleges are set to close in nine counties due to Storm Eunice.
It comes after red weather warnings have been issued for Waterford and Clare.
The two latest alerts mean red warnings are now in place in four counties - Cork and Kerry, in addition to Waterford and Clare.
Schools and colleges will shut in these counties, as well as five others where high winds combined with snowfall are expected to create “blizzard like” conditions.
These are Donegal, Mayo, Leitrim, Sligo and Roscommon.
