Families have been stranded, stations flooded and Covid testing centres closed as flash floods pummel London and southern England.
People living in Wood Street, Walthamstow, are reported to be in waist-high water inside their home, with emergency services racing to the scene to help.
Parents and their children are said to have been trapped in vehicles in four feet of water on the M11.
Dramatic footage also shows cars stranded on the A406 with parts of the road closed and rescue service staff wading through water.
Meanwhile, Pudding Mill Lane DLR Station in Stratford is underwater as torrential downpours spur chaos across the capital.
The Metropolitan Police have declared a ‘major incident’ with coronavirus testing centres in Waltham Forest closed tonight.
It comes after amber warnings for storms were issued for London and some of the Home Counties.
A spokesperson from the London Fire Brigade said firefighters were working with police to tackle flooding at Charlie Brown’s roundabout in South Woodford.
‘Met Police are currently at scene, Traffic Officers are on their way to the area to assist.’

IT consultant Jamie Curtis said it was the worst flooding he’d ever seen in the area.
He had to drive through water that was ’12 to 18 inches deep’ while driving through Clapham Common on his way home to Kingston, Hampshire.
Londoner Eddie Elliott, 28, cycled past the area outside Queenstown Road station, where he said the road had been ‘totally shut down’.
He said: ‘Having been born and raised in London, I have never seen anything quite like it.
‘Stands out as the worst I’ve experienced personally… totally shut down the whole road with buses stood broken down in the water.’
Met Office meteorologist Steven Keates earlier predicted parts of the south between south Suffolk and the Isle of Wight could be deluged by 100mm of rain in just a few hours this evening.
He said: ‘There’s torrential thunderstorms around yet again.
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.
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 wrote in a tweet: ‘Do not enter what could possibly be deep water.
‘Watch your speed and distance as stopping distances will be greater.’
It comes days after thousands flocked to beaches as the UK sizzled in a 32C heatwave.
Lightning set fire to houses in Andover, Hampshire, on Saturday morning, forcing residents to evacuate.
Neighbours heard an ‘enormous bang’ as the strike set two homes ablaze on Mercia Avenue, and an elderly woman, 70, was assessed by paramedics.
It will be a mixed bag when it comes to weather next week, with the Met saying: ‘Looking ahead to next week it will remain more widely unsettled with periods of rain expected though some sunshine too at times.’
