Streets all over west London have been hit by flooding, causing delays for traffic and public transport.
Residents from Harrow to West Drayton have been affected along with London Underground and Heathrow Airport services.
Some residents made the most of the weather and donned wellies to brave the waterlogged streets and parks.
Buses have been severely affected including Route E10 on Rowdell Road, Northolt which is blocked due to flooding.
At one point London Overground had no service between Willesden Junction and Harrow and Wealdstone. There were also severe delays from Euston to Queen's Park due to flooding at Kenton.
The registry office at Harrow Council was closed, while roads in the area were also closed off from Headstone Drive under the Bridge between Ellen Webb Drive/Cecil Road to Princes Drive.
H9 and H10 bus routes have been diverted and the A4090 Imperial Drive in Harrow has been shut at North Harrow station.
Drivers and cars have been caught out by waterlogged roads.
...and Heathrow Airport warned of delays for passengers making their way to catch flights:
The airport added on Twitter: "Please expect delays if travelling to Heathrow.
"We are working to clear these areas up as quickly as possible, sorry for the disruption."
The Met Office issued a yellow weather warning on Monday, as more torrential downpours made a very soggy start to the week.
The outlook for the bank holiday weekend looks brighter.
Scattered showers and sunshine are expected on Thursday, while Friday will see less rain.
The driest conditions over the weekend will be in the south, with a chance of some cloud and rain further north - but temperatures will remain a bit chilly.
Early indications suggest conditions will improve next week.
