Storm Boelo killed two men and left around 90,000 properties without power across the UK as it swept through on Sunday.

A man in his 20s died in north London when a falling tree struck his car, while a 60-year-old was killed by a tree in Dumfries and Galloway, Scotland. Two women were hospitalised after a tree fell on them in Aberfeldy. The Energy Networks Association said 90,000 customers remained without electricity as of Monday morning, with sustained winds of 50-85mph hampering repair efforts in Scotland and northern England .

The Met Office issued a yellow warning for strong winds from 18:00 on Monday to 03:00 on Tuesday across western England, Wales, Scotland, and eastern Northern Ireland, with another warning for northern Scotland from 03:00 on Tuesday. Wind gusts peaked at 85mph in Machrihanish and 84mph in Stornoway and Capel Curig over the weekend .

Transport and infrastructure faced severe disruption. Network Rail reported closures on the Crianlarich to Oban and Inverness to Wick and Thurso lines, while ScotRail said most services were running. CalMac and NorthLink Ferries warned of possible cancellations until Thursday. Some schools in Scotland closed due to lack of power, heating, or water .

Businesses also suffered. Marcus Reed, operations director at Wax Lyrical in Cumbria, said his factory and shop would remain without power until Tuesday evening, forcing him to turn away employees and customers during the busy pre-Christmas period. "To lose two days manufacturing and distribution is going to be really disruptive," he said .

Leo Slade, CEO of the Energy Networks Association, called it "a tough weekend" and noted that engineers could not safely restore power until the weather system passed. He added that the UK’s power network was resilient but that a debate was needed on further investment to mitigate future storms linked to climate change .
