The power outage has occurred due to Storm Brendan as it leaves over 21,000 homes and businesses without power across the nation.

They are advising the public to be aware of potential dangers and to heed the advice "Stay Back, Stay high and stay dry."
Tipperary County Council is echoing that sentiment and advising drivers to take extreme caution on the roads and to watch out for fallen trees and debris.
