A man in his 20s died a couple of hours later. A tree fell onto his moving car in Mill Hill, Finchley, north London. London's Air Ambulance sent a trauma team. The London Ambulance Service and the Metropolitan Police say he was pronounced dead at the scene.
Separately, Police Scotland has recovered a body near Largs, on the Firth of Clyde. It has not been formally identified. Police have told the family of Jim Withers, an 82-year-old man from Johnstone, that a body has been found. One report says the search for a man overboard from a ferry actually began more than a week before Storm Boelo arrived.
That's everything we know.
Why this mattersSo let's start with the scale of this.
Two confirmed deaths from falling trees, hundreds of miles apart, in a single day. And a six-figure number of homes without power as winter starts to bite.
Wind gusts peaked earlier today at 85mph in Machrihanish, Argyll and Bute. And 84mph in both Stornoway and Capel Curig, North Wales.
A Met Office amber wind warning covered Scotland and parts of northern England until 9pm this evening. A yellow warning covered the north of England too — Liverpool, Manchester, Leeds, Sheffield, Newcastle — and North Wales, for the same hours.
And the damage goes well beyond the two deaths.
Two women were taken to hospital in Aberfeldy, Perth and Kinross, after a falling tree hit them. The main road between Skelmorlie and Largs was badly damaged. A number of businesses in Largs flooded overnight.
In Dumbarton, phone shop owner Muhammad Zubair Ashraf is facing between £5,000 and £10,000 of flood damage. He says quote "heartbroken".
That's one shop owner. Multiply that across the country.
Several trunk roads in Scotland were shut — the A1 at Ayton, the A75 near Collin, the A82 at Bridge of Orchy, the A78 at Skelmorlie, the A83 at Kilchenzie. The M74 and M8 were both briefly closed overnight too, one for a fallen tree, one for flooding. Both reopened before 5am.
Ferries were disrupted. So were some flights to and from Belfast, Glasgow, Aberdeen and Dublin. So were trains across the UK.
Four flood warnings are in place across England and Wales. Seventeen more across Scotland.
The Scottish Government's Resilience Room met this afternoon to discuss the response. And here's the thing — they're warning more bad weather could arrive early this coming week.
Because it isn't over.
Met Office forecaster Aidan McGivern says the next two days will look much like Boelo did. The strongest winds will hit the north of the UK again, with gusts of up to 70mph possible. If an amber or red warning gets triggered, the next storm on this year's list is called Chloe.
So this storm has already cost two lives and cut power to hundreds of thousands of homes. And the Met Office is warning the next one could be close behind it.
One thing is still not known. Whether the body found at Largs is Jim Withers. Or whether it has anything to do with this storm at all.
