Emer Flood, a forecaster with Met Éireann said that the weather this week is below average temperatures for the time of year.
“We have a cold air mass moving down over the country at the moment from the north, so that is going to give quite cold conditions tonight with a late season frost,” Ms Flood said on Monday morning.
The ESB said that there had been “a few relatively small power outages” on Monday morning, which their crew had been responding to as they arise.
