A new Status Orange Weather warning has been issued for three South East counties.
The low temperature and ice alert details that it will be "extremely cold on Wednesday night with widespread temperatures below -5°C leading to severe frost & ice."
The warning adds to an existing Status Yellow weather alert for low temperatures for Wexford and Waterford until Friday. Met Éireann says it will remain "very cold through the week with widespread sharp to severe frosts and icy stretches.
"Some showers of hail, sleet and snow will occur, mainly near coasts. Accumulations at lower levels are expected to remain low. Freezing fog will occur at times, with winds remaining light over land."

Coldest day in 12 years
Ireland's cold snap is likely to continue until later in the week, according to Met Éireann's senior forecaster Gerry Murphy.
Mr Murphy told RTÉ's Morning Ireland that fog proved to be the most significant obstacle for drivers on Monday after Met Éireann confirmed it was the coldest day on record since 2010.
"It was a very foggy day over much of the country. Some places in the south weren't quite as foggy. So visibility was very poor throughout the day.
"In Ballyhaise in Co Cavan the temperature did not rise above minus 3.1 degrees across the day and that was the coldest daytime temperature since 2010, he said.
"The lowest temperature overnight was in Ballyhaise in Cavan with minus 6.9 degrees. Temperatures are in general ranging between minus one and minus six degrees. Once again frost and significant ice on the roads. Another morning for taking great care."
Mr Murphy added that it will remain very cold over the coming days.
"The nighttime temperatures are still going to drop to minus 7 possibly minus 8 on a couple of the nights. We don't anticipate that the fog is going to be as much of a problem as it was yesterday. But really for the most part dry but very cold, with severe frost and ice on the roads.
Then as you move into Friday some wintry showers returning to the West. Some rain and sleet possibly for a time on Saturday and at the moment it does look like we will see milder air pushing up on Sunday bringing with it rain and possibly some sleet and snow as well."
