The storm brought high winds, with gusts reaching up to 141km/h (88mph), according to Met Éireann. These winds caused widespread damage to the electricity network, affecting areas such as the North West, Midlands, and South East most severely.

At the height of the storm, nearly 400,000 customers experienced power outages. By 5 p.m. on Sunday, ESB Networks reported that power had been restored to the majority of affected properties, although tens of thousands remained without supply.

The utility company compared the storm’s impact to Storm Ophelia in 2017, which left 385,000 customers without power at its peak but caused more widespread disruption across the country.

ESB Networks said all crews and partner contractors were working through Sunday night under challenging conditions to restore power. They also announced that teams from the French utility company Enedis would arrive on Monday to assist with repairs in the hardest-hit areas.

Despite their efforts, ESB warned that significant numbers of customers would remain without electricity for several days, with some facing outages lasting up to a week. The public was urged to stay safe, avoid downed power lines, and report any damage to the network by calling 1800 372 999.

Meanwhile, An Post resumed deliveries in many areas on Sunday after postal services were disrupted the previous day.

“In severely affected areas, deliveries will resume as soon as it’s safe,” a spokesperson said. “Thanks to ESB’s tireless efforts, we expect all post offices to reopen on Monday.”
