LONDON - Nearly 300,000 homes were left without power in Britain and France on Monday and trains and planes were cancelled as a fierce storm battered the region, leaving at least two people dead.

A 17-year-old girl died after a tree fell onto the static caravan where she was sleeping in Hever, southeast England, and a man in his 50s died when a tree fell on his car in Watford, north of London, police said.

The rough conditions at sea forced rescuers to suspend the search for a 14-year-old boy who was washed out to sea from a beach in East Sussex on England’s south coast on Sunday.

More than 450 people were stranded for several hours on two ferries outside the port of Dover after it was closed to sea traffic, as huge waves lashed the coastline on both sides of the Channel.

Winds reached 99 miles per hour (159 kilometres per hour) on the Isle of Wight off the southern English coast, according to Britain’s Met Office national weather centre.

Heavy rain and winds of 80 mph elsewhere brought down hundreds of trees, while a crane fell onto the roof of a government building in central London. Police said nobody was hurt in that incident.

The Energy Networks Association, an industry body, said 220,000 homes across Britain were without power, as electricity lines were knocked down across the country.

In northern France the storm left some 65,000 homes without power early Monday, according to the ERDF distribution network, after wind gusts reached 139 kilometres per hour. Earlier ERDF had estimated 75,000 homes were affected.

Southern England bore the brunt of the storm, with train operators cancelling services across the region in anticipation.

Many commuters delayed their journeys until it passed, leaving central London stations eerily quiet during what normally would have been the rush hour.

The capital’s Heathrow airport cancelled 130 flights, about 10 per cent, while delays were reported on the Eurostar cross-Channel train service due to speed restrictions.

Meanwhile, more than 30 firefighters were deployed to a gas explosion in Hounslow, West London, after a falling tree caused a gas line to rupture. Three houses collapsed and two others were damaged, the fire service said.

Several major bridges were also closed, including the Severn Bridge over the estuary between England and Wales.

The Met Office said 50 millimetres (almost two inches) of rain fell in some areas overnight as the storm tracked eastwards across Britain.
