Two people were killed as storm swept the southern parts of Britain on Monday morning, cutting power supplies and disrupting traffic.

Both were killed by trees falling in the storm, according to local reports.

One of the victims was a 17-year-old girl, who was sleeping in Hever, Kent at 7:20 a.m.. A tree collapsed and crushed her caravan. She was pronounced dead at the scene.

A man in his 50s was killed in his car, which was battered by a toppled tree in Watford, Herts.

Trees fell in the high wind also cut power supplies to 220,000 homes, while many roads were forced to close.

The numbers are subject to changes as effect of the storm still lasts.

The Met Office said the gale at the Needles, Isle of Wight, reached the speed of 159 km per hour at 5 a.m. Monday morning.

Martin Young, Chief Forecaster, said in a press release on the Met Office's website: "While this is a major storm for the UK, we don't currently expect winds to be as strong as those seen in the 'Great Storm' of 1987 or the 'Burns Day storm' of 1990."

Sources with the Heathrow airport confirmed that some 130 flights were cancelled, and suggested passengers check before making their journeys.

Railway companies significantly reduced train services on Monday morning, while Easyjet, a local airline company, warned passengers to plan in advance as no train would be running between city center of London and major airports including Luton, Gatwick, Southend and Standstead before 9 a.m.

TfL (Transport for London) reported severe delays of several lines, as well as suspension of the overground services on its website. The changes brought troubles to commuters. A picture on BBC website showed a long queue outside an underground station in London.

The storm also affected the UK government.

Deputy Prime Minister Nick Clegg said on his twitter that a press conference was cancelled after a crane collapsed on top of the Cabinet Office.

"Today's press conference moved to a day when there isn't a crane on the roof and journalists travelling on the train are able to join us," he tweeted.
