Around 7,000 homes and businesses are without power this morning after Storm Atiyah.
Parts of the southwest are among the worst affected areas, with ESB Networks saying its crews are working to restore power to impacted areas as soon as possible.
Meanwhile, a major clean up is expected today due to fallen trees and debris around the country.
A number of weather warnings that were in place overnight have been lifted as of 6am this morning.
Kerry - where there was a status red wind warning in effect yesterday evening - was among the worst impacted counties.

Drivers are being urged to take care on the roads this morning following the bad weather overnight.
National Directorate for Fire and Emergency Management spokesperson Keith Leonard said: "The key advice to road users today is that the roads remain very dangerous.
"There's a lot of hazards from trees down and debris across roads.
"Local authorities are doing their best to clear these, but we would ask motorists... [to think about] the safety of their journey, and be mindful of other road users as well."
Meanwhile, Irish Rail says services are operating as normal this morning - with "no issues" arising from the storm.
