Torrential rain has flooded roads and Tube stations in London after thunderstorms struck the south of England on Sunday.

Greater Anglia trains into London from Essex have been disrupted because of a flood on the track and a tornado was even spotted in Essex.

Essex Weather Centre said it was likely Essex would also be seriously affected by thunder storms tonight. Essex Fire and Rescue Service has been called out to at least 20 calls this afternoon. 

Essex Fire and Rescue Service said its control centre had been inundated with calls from people in Harlow and Chigwell after flash flooding.

Group Manager Mark Eaglestone said:“Firefighters from across the County have been working very hard to help as many people as possible who are experiencing flooding to their homes particulary in the Chigwell and Harlow areas.

“We are prioritising incidents which involve vulnerable members of the community and flooded properties with serious safety concersn such as where water is affecting electrics.

“We are expecting the rain to reduce within the next hour, but there will still be a substaintial amount of standing water so more flooding is possible. We will continue to help as many people as possible.”

Locals on a street in Woodford have had to block floodwater from entering their homes.

Mariya Peeva said her son and neighbours worked quickly with buckets, brooms and wooden boards to create flood defences and scoop the water away from their homes.

“My son went to buy some food from the local shop – by the time he came back the whole street and the pavement were already flooded and the water was coming into our front door,” the 46-year-old told PA.

The restaurant manager said one of her neighbour’s bedrooms was flooded, but another neighbour arrived with a pump and was able to drain the water from the home.

A London resident said flooding in the city was the worst he had seen in his lifetime, while water gushing from an Underground station was caught on video.

Londoner Eddie Elliott cycled past the area outside Queenstown Road station, where he said the road had been “totally shut down”.

“Having been born and raised in London, I have never seen anything quite like it,” the 28-year-old writer told PA.

“Stands out as the worst I’ve experienced personally… totally shut down the whole road with buses stood broken down in the water.”

Jamie Curtis said the roads near Clapham Common were blocked due to floodwater which was “12 to 18 inches deep”.

“(I’ve) not seen that level of flooding in London before,” he said.

The Met Office has issued an amber warning for storms covering London and some of the Home Counties where homes and businesses are at risk of flooding, lasting until 7pm on Sunday.

A yellow warning for storms which could cause travel and power disruption also covers a wider area of the south from Norwich to Plymouth, and lasts until midnight.

Met Office meteorologist Steven Keates said parts of the south between south Suffolk and the Isle of Wight could be deluged by 100mm of rain in just a few hours on Sunday evening.

“There’s torrential thunderstorms around yet again,” he said.

“Into the evening, from Norfolk to Bournemouth we are going to see some pretty lively showers.

“Torrential downpours, thunder and lightning and potentially some hailstones are settling in the south.”

Mr Keates said the storms are being caused by a “convergence” of air currents, due to warmth in the earth’s surface from the recent heatwave rising into cooler air in the atmosphere.

It comes after lightning set fire to houses in Andover, Hampshire, on Saturday morning, forcing residents to leave.

Neighbours heard an “enormous bang” as the strike set two homes ablaze on Mercia Avenue, and a 70-year-old woman was assessed by paramedics.

Kingston Police, who oversee a borough in the amber zone for storms, warned motorists to “drive carefully” and remember they are “not driving a submarine”.

The force said in a tweet: “Please remember to drive carefully.

“Also remember that you’re not driving a submarine.

“Do not enter what could possibly be deep water.

“Watch your speed and distance as stopping distances will be greater.”

The rain brought an end to the heatwave earlier this week, potentially disappointing anyone who hoped for a dry, sunny trip to the coast.

The rest of the country was forecast to experience a cloudy, more settled end to the week while sunshine is expected in Scotland.

Temperatures are set to rise in most places again on Monday as the storms clear, with the mercury predicted to reach 26C in London, 25C in Edinburgh, 24C in Cardiff, and 22C in Belfast.

The Met Office has predicted early cloud in some northern and eastern parts which will move up to Scotland, and sunny spells and scattered showers in most places throughout the day.

Essex firefighters have given the following advice:

If you or someone you know is currently experiencing flooding to their home our advice is:

  • If possible block your doorway as best you can to stop water entering your home
  • Move yourself and any personal belongings upstairs
  • Do not try to walk or drive through flood water – the roadway may be damaged and it is very common for man holes to be displaced during floods which pose an extra risk
  • If the flooding is not affecting residential properties, please call your local authority to help
  • The fire service is unable to provide sandbags
