The storm brought gusts of almost 80mph (129km/h) to some areas over the weekend, causing flights and ferries to be cancelled. Around 40 flights were cancelled at Belfast International Airport and about 30 at Dublin Airport. About 12,500 properties were without power in Northern Ireland at the peak, NIE said.
In the Republic of Ireland, an ESB spokesperson said a number of homes, farms and businesses still had no electricity on Monday morning, with crews working to restore supply. About 5,000 properties were without power on Sunday evening.
The Department for Infrastructure reported around 470 incidents including fallen trees and flooding across Northern Ireland. The Foyle Bridge was closed on Saturday due to high winds but reopened on Sunday evening. SDLP MLA Mark H Durkan said the prolonged closure caused major traffic congestion and showed the city needed a third bridge. "The infrastructural capacity of Derry needs increased; I don't think two vehicular bridges for a city of this size and a population of this city is enough," he told BBC Radio Foyle's North West Today.
A Translink spokesperson said some bus services were diverted over the weekend due to fallen debris and rail restrictions were in place. "Stormy conditions also increase 'leaf fall' at this time of year which can impact train services and our infrastructure crews will be deployed to clear any debris potentially blocking railway lines," they added.
A Met Office yellow warning for strong winds is in effect from 18:00 GMT Monday until 03:00 Tuesday along the Antrim and Down coasts, with gusts up to 50mph (80km/h) and up to 65mph (105km/h) on exposed coasts.
