A cold St Patrick's Day weekend is being predicted with a risk of snow showers and a "significant wind chill".
Met Eireann has forecast that there will be "a few wintry showers" in parts on March 17.
In a forecast it said: "Cold and breezy on St Patrick's Day, with a significant wind chill due to fresh and gusty easterly winds. Afternoon temperatures will be just 1 to 3 degrees in eastern half of the country and between 4 to 6 degrees further west.
"Most places dry, but a few wintry showers are likely in the east and south.
"Very cold Saturday night, with mainly clear skies and some snow showers in the east and southeast. Amounts are looking small at this stage. Lowest temperatures -1 to -4 degrees.
On Sunday temperatures are expected to peak at around 4C, but easterly winds will make it feel even colder.
Met Eireann said: "Some sleet or snow showers will occur again, mainly in eastern areas. A few flurries are possible elsewhere.
"Another very cold night on Sunday. Lowest temperatures 0 to -5 degrees with a widespread severe frost. Less cold perhaps on Leinster coasts. "
Rain along the east coast will clear this morning & it will become mainly dry. There will be some sunshine in west Munster but a few showers as well.
