An 84-year-old man died after a car collided with a fallen tree as Storm Isha brought winds topping 100mph to the UK.
Police in Scotland say the man – a front-seat passenger – was pronounced dead at the scene in Grangemouth on Sunday night, while others in the car were unhurt.
It comes as commuters faced travel disruption on Monday morning, with tens of thousands left without power.
Rush-hour trains were axed for many as more cancellations and delays are expected for rail, air and sea travellers.
At least 30,000 people have no power across the north of England and Scotland, with another 40,000 affected in Northern Ireland, according to Lawrence Slade, the chief executive of the Energy Networks Association.
A yellow warning for wind is in place for the entire UK until midday, after the Met Office had issued two amber wind alerts and a red warning for parts of northern Scotland, which have expired.
At its height the storm brought winds gusting up to 107mph on the Tay bridge in Scotland.
There was still the possibility of more damage to homes and buildings, falling trees, power cuts, flying debris, large waves and even some flooding in places into Monday morning.
Key points:
• Electricity North West said crews have been stood down until Tuesday evening due to the conditions;
• Network Rail has imposed 50mph speed restrictions across most routes;
• Scot Rail has cancelled all rush-hour trains and services may not resume until “later on Monday”;
• Sellafield nuclear site closed on Sunday as a precaution.
In northwest England, crews won’t carry out repairs until Tuesday evening due to the conditions, as Electricity North West says 8,500 remain without power.
Scottish and Southern Electricity Networks (SSEN) said weather conditions were “more severe than initially forecast”, with “full network restoration not expected today” and 10,500 properties having no power supply as of 8.45am.

Storm Isha is the ninth named storm to hit the UK since the season began in September.
Each storm is named when it poses a risk to people and they are given names beginning with consecutive letters of the alphabet.
The record number of named storms in one year is when the Met Office began the practice in 2015/16, with Storm Katie being the 11th and final storm of the season.
