A burst water main has left Londoners trapped in their homes without electricity and water for more than 14 hours.
Footage posted on social media showed cars completely submerged in water on a residential street and people wading through huge puddles on their morning commute.
One boy was even filmed climbing out of his window to get to school as the water had barricaded his front door.
Thames Water said the pipe burst last night, but it didn't know what had caused the damage.

Firefighters were filmed knee-deep in the floods with rubber dinghies to deliver bottled water to trapped residents.
Residents were seen standing on walls to avoid getting soaked while separate footage showed water pouring from the damaged pipe into a nearby canal.
Kris Lee, whose home overlooks the flooding, told the Hackney Gazette: 'The pipe burst where the big tree is that's stuck in the middle of the hoarding.
'It started at 10pm and it's getting worse and worse. The London Fire Brigade are here now but they are trying to suck the water out through a 6in pipe. The burst pipe is 36in. I think they're fighting a losing battle.
