Londoners are being warned to brace for heavy rain tomorrow, with a yellow warning in place until Friday morning.

The downpour, expected from 5am tomorrow (Thursday) to 10am on Friday (September 27), could bring the potential for some flooding and disruption to transport, according to the Met Office.

People across London are advised to “stay alert” and take precautions as the weather worsens tomorrow.

The heavy rain expected this Thursday could lead to power outages in homes, localised flooding, delays or cancellations on train and bus services, and difficult driving conditions, with some roads potentially closing, according to the Met Office.

Some areas may also become inaccessible due to flooded roads, with a small chance of fast-flowing or deep water posing a danger to life.

While some areas may avoid the worst of the weather, heavy rain is expected to spread widely across parts of England and Wales on Thursday evening and into Friday morning.

Though details are still uncertain, some places could experience 20-30 mm of rain in just 2-3 hours, and possibly 40-60 mm in 4-6 hours.

Earlier this week, London recovered from flash flooding which saw homes damaged and travel disrupted.

London Fire Brigade responded to 350 emergency calls on Monday (September 23) due to overnight flooding, while three tube lines were suspended.

Train services were also affected, as London Northwestern Railway said its Marston Vale line, which operates services between Bedford and Bletchley, would be suspended until September 30.

In Wimbledon, a driver was rescued by firefighters after his car was stranded in flood water following severe weather in the middle of the night.

Firefighters attended the vehicle, which was stranded in floodwater on Manor Road in Wallington at 1.15am on Monday (September 23).

The vehicle was stranded in around one metre's worth of floodwater.

One person was assisted from the vehicle by firefighters and a crew from Wallington Fire Station put a cordon in place.
