Donegal County Council gritters are also back in action overnight on all main routes.
However with temperatures falling to -5c, the council says that motorists should not assume that any road is ice free and to drive with extreme caution.
Gardai and the Road Safety Authority have issued similar warnings.
This is the Met Eireann warning: Snow-ice Warning for Dublin, Carlow, Kildare, Kilkenny, Laois, Louth, Wexford, Wicklow, Meath, Donegal, Mayo, Cork, Kerry, Tipperary and Waterford.
Scattered snow showers this evening, tonight and on Monday will give accumulations of between 3 and 8 cm.
Snow will lie at lower levels as well as on high ground. Amounts will be highest in coastal counties of Leinster.
Fresh to strong, gusty northeast winds will make for blizzard conditions in places during snow showers. A widespread sharp or severe frost tonight, lingering in many areas tomorrow.
