Around 500 homes in Fermoy in Cork are still without power this lunchtime along with less than 30 homes in Ballybeag in Wicklow.

Met Éireann forecaster Joanna Donnelly said the weather conditions for the coming nights will not be as severe.
"There will still be some showers around and some of them will be heavy," she said.
"[There is] still a risk of thunder too for the rest of today and tonight as well. Not quite as significant as it was last night, but certainly it is still there."
