A 'flash flood' has hit London following the Met Office's amber thunderstorm warning.

Social media users have been sharing their experiences of the rising water levels after the national weather service confirmed the amber weather alert earlier on Wednesday.

There is currently an amber thunderstorm warning for those living in London and the South East of England until 10pm on August 17.

Other areas affected by the amber warning include other parts of the South East such as Brighton, Chelmsford, and Canterbury among others.

Much of the south-east is covered with a yellow thunderstorm warning including neighbouring Hertfordshire as well as Berkshire, Wiltshire and much of the South Coast.

One user with the handle, @AndrewsVisual , shared a shocking video as the heavy rain arrived, writing: "The Flash flood that just happened in London is insane… the rain was incredibly mad."

The video, which was filmed at King's Cross, shows an unnamed man knee-deep in water as he attempts to sweep the water away.

Meanwhile, various vehicles including several cars and a London bus are shown to be driving through the deep water.

Met Office issues amber weather warning for thunderstorms in South East London

Met Office has said that we should expect the following:

  • Flooding of homes and businesses is likely and could happen quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds
  • Fast flowing or deep floodwater is likely, causing danger to life
  • Where flooding or lightning strikes occur, delays and some cancellations to train and bus services are likely
  • Spray and sudden flooding probably leading to difficult driving conditions and some road closures
  • Some communities likely to become cut off if roads flood
  • Power cuts likely to occur and other services to some homes and businesses could be lost

A Met Office spokesperson said: "Heavy showers and thunderstorms are expected to break out today leading to some flooding and disruption.

"Some places will miss these, but where they do occur, 30 to 50 mm of rain could fall in less than an hour and a few places may see in excess of 100 mm in a few hours where storms are slow moving.

"Lightning and hail will be additional hazards. Showers and storms will slowly die out this evening."
