Gusts close to 100 mph batter the southern coast of England

(CNN) —  

Southern Britain is getting hammered by a major Atlantic storm, which could be its worst in years, and the search for a missing teenager swept out to sea ended for the night with no sign of the boy.

Wind gusts as strong as 99 mph battered the south coast of England, and authorities warned of travel disruptions across the region.

At least two storm-related deaths were confirmed Monday in England, and a third person was missing after being swept out to sea.

Police in Kent said a 17-year-old girl was killed when a tree fell on the home where she was sleeping in Hever, south of London. A man in his 50s was killed when a tree fell on a vehicle in Watford, northwest of London, according to Hertfordshire police.

A man in his 50s was killed when a tree fell on a vehicle Monday in Watford, northwest of London, according to Hertfordshire police.

In Germany, five people were killed, four of them by fallen trees. A woman in the city of Heiligenhafen was killed when a wall supporting a terrace fell on her.

A tourist was killed by a falling tree in Amsterdam, police said.

And in France, the body of a woman was found on a beach near Belle-Ile. Witnesses said the woman was swept away by a wave.

As the storm approached, rescuers had to suspend their search for a missing teenager believed to have been swept out to sea. The unidentified teenager disappeared from Newhaven, East Sussex, on the southern coast, according to the Royal National Lifeboat Institution.

Authorities were checking whether two other deaths were related to the storm. A man and a woman died – and a third person was hospitalized – as a result of a gas explosion at a house in Hounslow in West London, London’s Metropolitan Police said. Investigators were checking whether a tree that had fallen in the area damaged gas pipes and caused the blast.

The storm also affected France, Belgium and the Netherlands. A woman was killed by a falling tree in Amsterdam, local media reported. Officials said 42,000 homes in northern France were without electricity. Overnight, the number of homes in France without power peaked at 75,000.

The strongest wind gusts in England – 99 mph – were recorded on the Isle of Wight, which is off the southern coast, the Met Office said.

The storm cut power to people across the southern part of England.

The Energy Networks Association, which represents British and Irish power operators, said that 220,000 homes were without power in the southeast, southwest and midlands of England.

Energy companies said they were working to restore power as quickly as possible.

Authorities warned that the heavy rain from the storm could cause flooding in some areas. Eighteen flood warnings were in place in southwest England, the government said.

In the southeast, Sussex Police said they had had reports of more than 125 trees down across the county. They warned drivers to be careful, especially on smaller roads.

Network Rail, which manages Britain’s rail infrastructure, said Monday that more than 100 trees were on rails in the network across the southeast.

Heathrow Airport said it was reducing the number of flights Monday because of the severe weather.

Weather forecasters had said before the storm arrived that it could be the region’s worst in a decade.

But conditions were not as severe as those during the Great Storm of 1987, which was responsible for the deaths of 18 people in Britain and four in France.

In 1990, the Burns Day Storm left a trail of destruction from the Isles of Scilly to Denmark, killing 100 people, including 47 in the British Isles, according to the Met Office.
