Storm Boelo knocked out power to thousands of homes and forced flight cancellations across Ireland on Sunday after bringing winds gusting up to 85 miles per hour overnight.

Northern Ireland Electricity reported 7,000 customers without power, while approximately 41,000 homes, farms and businesses across the Republic of Ireland lost electricity. ESB Networks, which operates in the Republic, said crews deployed to affected areas expected to restore power to the vast majority of customers by Sunday evening. Properties in Ireland's north-west region faced the heaviest impact.

The Department for Infrastructure recorded about 350 incidents including fallen trees and flooding. Foyle Bridge in Londonderry remained closed Sunday morning, though other roads gradually reopened after initially being impassable. Police urged drivers to exercise caution due to debris.

Belfast City Airport cancelled flights to London, Aberdeen, Glasgow, Edinburgh and Liverpool. Belfast International Airport cancelled 17 flights Sunday morning, with an airport spokesperson saying the storm "continues to cause some disruption to flights." Dublin Airport saw 12 inbound and 12 outbound flights cancelled, mainly due to adverse weather conditions affecting other countries as well. Airports advised passengers to check directly with airlines.

Ferry services also faced disruption. Stena Line cancelled sailings from Belfast to Cairnryan and Liverpool on Sunday morning, as well as the Cairnryan to Belfast route. P&O Ferries cancelled sailings at 08:00 and 12:00 GMT from both Cairnryan and Larne, though the 16:00 GMT departures were expected to proceed as scheduled. The Dublin to Holyhead Stena Line crossing remained unaffected.

Wind gusts reached 78 miles per hour at Orlock Head in County Down on Saturday, with Malin Head in Donegal recording 83 miles per hour. Castlederg and Lough Fea in the Sperrins received nearly 40 millimeters of rain. A yellow wind warning remained in place for County Donegal until 15:00 local time Sunday, with gusts expected to persist near 70 miles per hour in exposed coastal areas through the afternoon.

Another storm system with strong winds was forecast for Monday and Tuesday.
