LONDON The death toll from a severe storm battering northern Europe has risen to 13, with the United Kingdom and Germany hit the hardest.
A major storm with hurricane-force gusts lashed southern Britain, the Netherlands, and parts of France and Germany on Monday, knocking down trees, flooding low areas and causing travel chaos.
U.K. officials reported at least five deaths. Four people were killed Monday in Germany, adding to two deaths at sea off the German coast Sunday.
Weather forecasters say it's. Gusts of 99 miles per hour were reported on the Isle of Wight in southern England, while gusts up to 80 mph hit the U.K. mainland.
UK Power Networks officials said up to 270,000 homes were without power. Flood alerts were issued for many parts of southern England and emergency officials said hundreds of trees were knocked down by gusts.
London's Heathrow Airport, Europe's busiest, cancelled at least 130 flights and express trains between central London and Gatwick and Stansted airports were suspended. Huge waves prompted the major English port of Dover to close, cutting off ferry services to France.
A nuclear power station in Kent, southern England, automatically shut its two reactors after storm debris reduced its incoming power supply. Officials at the Dungeness B plant said the reactors had shut down safely and would be brought back online once power was restored.
In central London, a huge building crane near the prime minister's office crumpled in the gusts.
Thousands of homes in northwestern France also lost electricity, while in the Netherlands several rail lines shut down, airport delays were reported. Dutch citizens were warned against riding their bicycles - a favored form of transport - because of the high winds, and Amsterdam's central railway station was shut down by storm damage.
Some English rail lines also closed Monday morning, and some roads were closed due to fallen trees and power lines. There were severe delays on many parts of the London Underground and London Overground trains were delayed several hours.
In Britain, police said a 17-year-old girl in Kent and a man in his 50s in Watford were killed after trees fell on her home and his car. A London man died in an apparent gas explosion at his home and a teenage boy drowned Sunday while playing in the surf at Newhaven.
Amsterdam police said a woman was killed by a falling tree and German authorities said two others were killed when a tree fell on their car in Gelsenkirchen, western Germany.
A stretch of the A71 autobahn in the central German state of Thuringia was closed because of winds gusting up to 62 mph.
The storm has hurricane-force gusts but is not classified as a hurricane since it did not form over warm expanses of open ocean like the hurricanes that batter the Caribbean and the eastern United States, according to Britain's national weather service, the Met Office.
Britain does not get hurricanes because hurricanes are "warm latitude" storms that draw their energy from seas far warmer than the North Atlantic, the agency said.
The storm is not named and does not have an "eye" at its center as hurricanes typically do. On social networks it has been called stormageddon.
Sweden's Meteorological Institute upgraded its advisory Monday, warning that a "class 3" storm that could pose "great danger to the public" as it hits western and southern Sweden in the evening.
Still, the damage was less than feared in the 48 hours leading up to the storm, when the British press raised alarm bells about a possibly catastrophic storm.
British Airways said its long haul flights were expected to operate normally but domestic and European flights were operating on a reduced schedule with some cancellations. It said Gatwick and London City airport operations should not be affected.
