MET Éireann has issued a Status Yellow weather alert for over half of Ireland as the nation prepares for a snowy St Patrick's weekend.
Some 15 counties in Leinster, Ulster and Munster are set to get the worst of the cold weather.
The warning is in place until 11.59pm on Sunday for Dublin, Carlow, Kildare, Kilkenny, Laois, Longford, Louth, Meath, Offaly, Waterford, Westmeath, Wexford, Wicklow, Cavan and Monaghan.
Night-time temperatures as low as -4c will move in over the bank holiday, so take that into account if you're out celebrating late.
