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

The worst flooded roads were totally shut down by authorities due to fear of motorists getting stranded or even drowning.

Transport for London buses stood broken down in 12 to 18 inches deep of rain water.

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.

Torrential downpours, thunder and lightning and potentially some hailstones are settled in the south.

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.

Many London commuters said that they have not seen that level of flooding in London before.
