"Police attended the sudden death of a man, aged in his 20s, in the Slieve Gullion Park, Drumintee Road area of Newry this afternoon," said a spokesperson for the Police Service of Northern Ireland.
Earlier in the day, a woman in her 50s died in County Galway after the caravan she was sleeping in was blown down a coastal hill by the gusting winds of Storm Ali.
In a tragic freak accident, the caravan was lifted by the heavy winds and blown down a rocky hill on to Acton's beach at Claddaghduff, near Clifden on Wednesday morning. Gardaí were notified of the incident at 7.45am after winds in the area kicked up considerably.
Shortly afterward local emergency services found the caravan and accessed the scene. The woman’s body was “located on the stretch of coastline.” Ireland’s national broadcaster, RTÉ, reports.
It is believed that the woman was a tourist, visiting from Europe, and had been holidaying at a campsite in Claddaghduff, in Connemara.
Gusts of up to 89mph (143km/h) have hit Mace Head in Galway classing this as a serious wind event. Winds recorded in the area had reached Gale Force 11.
President Michael D Higgins said he was “deeply saddened to learn that storm Ali has already claimed one victim today in Claddagduff, County Galway.
“As President of Ireland, may I express my deepest condolences to her family. I would also take this opportunity to pay tribute to all those, in statutory and voluntary organizations around the country, who are helping and stand ready to assist their fellow citizens, and who are working to maintain essential services around the country.”
Storm Ali has left more than 55,000 homes and businesses in Ireland without power. Also due to the gusting winds dozens of flights, across the island, have been canceled.
A “Status Orange” wind warning remains in effect for more than half the country. Ireland’s meteorological experts Met Éireann have advised "extreme caution" in western coastal districts.
The storm, the first of the season for Ireland, is predicted to move quickly eastwards. However, forecasters had predicted heavy rain, flying debris, fallen trees, power cuts, flooding and travel disruption are possible in the worst-hit areas.
The Orange alert will remain in place until 1 pm on Wednesday. A less extreme Yellow warning will be lifted at 5 pm at the earliest.
