( CNN ) -- A major Atlantic storm packing hurricane-force winds pummeled England , France , Belgium and the Netherlands early Monday , knocking out power to 220,000 homes in England and blocking roads and railways with fallen trees . At least nine people were killed . 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-releated deaths were confirmed in England , and a third person was reported missing . Police in Kent said a 17-year-old girl was killed Monday morning 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 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 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 they said they did n't expect the conditions to be 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 .
