Record-breaking wind gusts of 122mph have been recorded in England as Storm Eunice batters Britain.
The jaw-dropping wind speed was provisionally recorded at the Needles on the Isle of Wight, the Met Office said.
Forecasters issued two rare red weather alerts over the winds amid dire warnings of a "significant risk to life".
Millions of people have been urged to stay at home for the day due to safety fears over the impact of Eunice, one of the worst storms to hit the UK in a generation.
Tens of thousands of homes have been left without power, while flights, trains and ferry services have been suspended, and roads, schools and businesses have shut as potentially record-breaking gusts of more than 120mph have been recorded in the most exposed areas.
Among the chaos includes:
Network Rail said a fallen tree around 50 feet (15 metres) long at Ewell West, Surrey is blocking the line between London Waterloo and Dorking, Surrey.
P&O Ferries has suspended all sailings between Dover and Calais.
National Highways said the Britannia Bridge, which connects the island of Anglesey with mainland Wales, is closed.
Both the M4 Prince of Wales Bridge and M48 Severn Bridge are closed to all traffic.
All trains in Wales have been cancelled
Roof of a lifeboat station in Sennon Cove, near Penzance, was blown off and left resting on power cables.
Elsewhere, passengers have been trapped on a train in Kent as Eunice wreaks havoc on traffic and travel amid warnings to stay at home over fears of safety.
South Eastern railway tweeted: "We're working on a plan to safely rescue passengers currently stranded on a train between Tonbridge and Sevenoaks. Apologies for the continued delay, we will get you on the move ASAP."
In London, where a red weather warning was put in place earlier today, city-goers are being urged to avoid any non-essential travel. Gusts were so powerful the Millennium Dome was spotted splitting open gusts rammed the iconic city skyline.
Mala Sharma said “more and more parts are getting ripped off”, adding, “it’s going to be a safety issue for people around”.
She told Yahoo News UK that it happened “right in front of my eyes” and that the damage “started off with a patch” but then a “chunk” of the dome roof ripped off.
