The southeast of England has been hammered by thunderstorms and torrential rain today, flooding London Victoria, and other stations, and prompting warnings of a "risk to life" from swift-moving, deep floodwater.

The severe downpours in London have caused considerable disruptions to public transportation by closing tube stations and flooding parts of the M25 and A406.

Commuters have been struggling to get home amid these disruptions.

Much of southern England is under a yellow thunderstorm warning till midnight, which means there is a chance of flooding, lightning strikes, snarled traffic, and power outages.

Up until 8:00 BST, it will continue to blanket a sizable portion of Kent.

The Environment Agency has issued 17 flood alerts in England due to the possibility of up to 100mm of rain.

Following weeks of intense heat and tinder-dry conditions, heavy rain on Tuesday caused roadways in England, Wales, and Scotland to become flooded.

According to the BBC weather presenter Simon King, Worksop in Nottinghamshire received 93mm of rain between 17:00 and 20:00 BST on Tuesday, nearly double the monthly normal of 54mm.

Cars have been spotted in Brent Cross driving across floodwater as the opposite side of the road is closed off owing to the deep water.

The Environment Agency advised against driving through floodwater, stating that a car can float in "only 30 cm" of flowing water and that the water is frequently deeper than it appears to be.

The Met Office has issued yellow and amber warnings for a sizable portion of England and Wales.

Roads are already flooded, drains are overflowing, and people are urgently trying to hold back floodwaters as a result of torrential rains that have hit large portions of the nation.

Today's thunderstorms were covered by an amber weather advisory from the Met Office in areas of England, including Chichester to Ipswich and London, Brighton, and Essex.
