Heavy rain has caused flash flooding across south London with severe transport delays and rivers running through the streets.

The deluge hit the capital between 2pm and 3pm this afternoon. Thunder and lightning accompanied the torrential rain, which is expected to continue through Tuesday afternoon. Some areas are predicted to receive 20mm of rain in a single hour.

Wallington was one of the worst hit areas. Locals took to social media to share their pictures from the floods, including shocking images of fully submerged cars and rivers running through the streets.

The weather has also caused travel disruptions. BBC Surrey issued alerts on twitter warning of delays between Sutton and Croydon.

Roads in Sutton were left flooded while problems were reported on the railway between Caterham and Purley where all lines are blocked.

The London Fire Brigade tweeted that they were attending a number of flash flooding and lightning strike calls in Mitcham and Croydon.

Temperature highs of 27C were recorded in London yesterday (Monday 6), following another fine day on Sunday.

The Met Office said that the “warm conditions across the country” allowed the rain, thunder and in some places hail to develop. Two yellow warnings for rain were also issued for Tuesday.
