"A yellow weather warning has been issued by the Met Office
Tornadoes could hit parts of London as thunderstorms drench the city, storm chasers are warning.
A yellow weather warning is in place for the whole of London from 6 pm today (Tuesday, June 18) to 9 pm on Wednesday (June 19).
Forecasters at the Met Office have said there is a high chance of thunderstorms, torrential rain, hail and lightning. This could mean flooding and disruption to travel.
Essex Live reports that some forecasters are even warning that tornadoes could hit South East England.
Parts of South London, Kent and East Sussex are the areas most likely to see a tornado but there is a chance they could hit other parts of the capital.
One storm chaser on the UK Weather World forum said that there is the potential "for a significant tornado event" during the spell of bad weather.
Funnel clouds, which are rotating columns of wind that become tornadoes if they touch the ground, are more prevalent in the south of England than the rest of the country.
Although the Met Office has no formal way of documenting the numbers of funnel clouds forming, the Met Office estimates that around 30 form each year.

The Met Office issue different colours of weather warning to help the public stay aware of the potential dangers caused by the weather.

A spokesperson for the Met Office, talking about the weather conditions expected over the next 24 hours, told MyLondon: "If you’re going to get a tornado, it is this sort of system."
In 2006 six people were left injured and 150 homes were damaged after a tornado tore through Kensal Rise in North West London.
According to the Met Office, there is a small chance that homes and businesses could be flooded during the predicted thunderstorms over the next 24 hours, causing potential damage to some buildings as a result of floodwater, lightning strikes, hail or strong winds."
