Storm Amy is set to batter northern parts of the UK with potentially life-threatening conditions as the Met Office issues amber warnings for exceptionally strong winds and heavy rainfall.
The powerful autumn storm could bring gusts exceeding 95 mph in exposed areas of western Scotland and up to 80 mph along western Northern Ireland’s coastlines. More widely across amber warning areas, winds of 60-70 mph are expected to cause significant disruption.
Neil Armstrong, Met Office Chief Forecaster, explained the severity: “Within the Scotland amber warning area, gusts in excess of 95mph are possible from Friday evening and into Saturday morning as Storm Amy brings a risk of power cuts and damage to buildings and trees.”
The timing of these warnings differs by region. Western Northern Ireland’s amber alert runs from 3pm until 8pm on Friday, while Scotland’s warning begins at 5pm Friday and continues until 9am Saturday. Both warnings highlight a danger to life, particularly near coastal areas where large waves pose additional risks.

Heavy rain adds to the danger, especially in western Scotland where 30-50mm could fall in just 6-9 hours. This combination of wind and rain has prompted warnings about potential landslides.
“BGS records show that landslides have been triggered in western Scotland by similar amounts of rainfall to that being forecast,” said Claire Dashwood from the British Geological Survey. “Both natural and infrastructure slopes are likely to be affected with potential for disruption to roads and railway within the warning area.”
The storm’s rapid development is linked to a weather phenomenon called “explosive cyclogenesis” – a process where storms intensify extremely quickly. Dr. Simon Lee, an atmospheric science expert, explained: “You can think of Amy a little bit like a surfer, which catches the jet stream. Amy catches this wave to perfection and it undergoes explosive cyclogenesis on Friday, which just means it rapidly intensifies.”
This development has been influenced by the remnants of Hurricanes Humberto and Imelda, which have accelerated the jet stream across the Atlantic.
Widespread disruption to travel networks is already beginning. In Northern Ireland, the Education Authority ordered schools in counties Antrim, Londonderry, Tyrone and Fermanagh to close at midday Friday “in the interests of safety.”
Transport Scotland’s Martin Thomson warned: “Storm Amy is set to bring heavy rain and strong winds to parts of Scotland and we expect to see disruption to the transport network in the warning areas. The rain and wind will bring difficult driving conditions, such as reduced visibility and surface water.”
Sarah Cook from the Environment Agency added a crucial safety reminder: “We advise people to stay away from swollen rivers and coastal paths, and not to drive through flood water as just 30cm of flowing water is enough to move your car.”
Storm Amy is particularly dangerous because it arrives in early autumn when many trees still have their full leaves, making them more vulnerable to being toppled by strong winds. This increases the risk of power outages and road blockages across affected regions.
Members of the public are urged to stay updated with forecasts, sign up for flood warnings where appropriate, and avoid unnecessary travel during the height of the storm.
