Storm Amy, the first named storm of the 2025/26 season, made a significant impact across the United Kingdom and Ireland on October 3, 2025, bringing severe gales and torrential downpours. The storm's rapid intensification led to widespread amber and yellow weather advisories.
Scotland experienced the brunt of the storm's fury, with wind speeds reaching approximately 100 mph (161 km/h) in exposed areas. This resulted in considerable transportation disruption, including the closure of bridges and roads due to fallen trees and flooding. Rail services were extensively suspended, leaving many travelers stranded. In Ireland, the storm also caused severe impacts. Tragically, a weather-related fatality was confirmed in County Donegal, where a man in his 40s died following an incident at a domestic residence, identified as Tommy Connors who died following a fall from a shed roof. At its peak, an estimated 234,000 properties across the UK and Ireland lost power. This figure included approximately 184,000 in Ireland and over 50,000 in Northern Ireland.
The storm's development was rapid, linked to the interaction of the remnants of Hurricanes Humberto and Imelda with a powerful jet stream over the North Atlantic. This led to explosive cyclogenesis, a process of rapid pressure drop, setting a new record for the deepest low-pressure system recorded in the UK for October. Storm Amy set a new record for the deepest low-pressure system recorded in the UK for October, with a pressure of 947.9 hectopascals (hPa) in Shetland, surpassing the previous record from 1988. The comparison article in Chinese (Simplified) mentioned the previous record was 950.9 hPa.
As of midday on October 4, approximately 49,000 homes and businesses in Ireland were still without power, with restoration in the most affected areas, particularly Donegal, expected to extend into the early part of the following week. Utility companies are working to restore electricity amidst challenging conditions, emphasizing public safety around damaged infrastructure. The storm's passage has highlighted the importance of community preparedness in the face of extreme weather events. The comparison articles noted that in total, over 263,600 power outages occurred across Ireland and the UK, and in Ireland, nearly 120,000 properties were without power at one point.
