Storm-force winds gusting up to 99mph have battered southern parts of the UK, bringing death, widespread travel disruption, flooding and power cuts.
A 17-year-old girl died after a tree fell on to her static caravan at Hever, Kent, and a man in his 50s died after a tree fell on to his car in Watford. A 14-year-old boy was feared dead after being swept out to sea at Newhaven, East Sussex.
The intense storm, one of the worst to hit Britain for a decade, swept in overnight, causing a chaotic start to the working week, leaving roads impassable because of fallen trees and disrupting rush-hour rail services.
UK Power Networks said 220,000 homes were without power as the storm cut a devastating path through southern counties in the early hours of Monday before hitting London and East Anglia with greater severity than anticipated.
Tracy Elsey, communications manager for UK Power Networks, told BBC Radio 4's Today programme: "We have still got about 40,000 people off in the south-east, which is our region which runs from Brighton up to Kent.
"In our east of England region, which goes from Essex up to the north Norfolk coast, we have seen a huge rise in reported power cuts. We have got 100,000 properties off power in the east."
Scottish and Southern Energy said more than 38,000 customers were without power in Cornwall, Devon and Somerset, while Western Power reported more than 3,800 power cuts in the same areas.
