Snow and sleet is forecast around the country for the next few days.
Met Éireann has issued a yellow snow and ice warning, which is in place until Wednesday afternoon.
Areas in the west and north are expected to get the heaviest snowfalls.
Snowfall is expected as a cold airmass passes over the country from Canada.
Meanwhile, snowfall in Dublin and nearby counties on the first day of meteorological spring has prompted a slew of frost-dappled snaps on social media.
