Thunderstorms are expected to cause flooding, lightning and power outages across parts of the UK, with warnings of road and transport disruption.

The Met Office has issued an amber warning for thunderstorms stretching from Norwich in East Anglia to Brighton on the south coast, including London, Chelmsford and Canterbury.

The warning is in place from 4pm to 9pm on Monday, with the Met Office saying thunderstorms and heavy rain may cause travel disruption.

Forecasters warned of sudden flooding which could lead to difficult driving conditions and road closures, as well as power cuts and flooding of homes and businesses.

"Flooding of homes and businesses is likely and could happen quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds," the Met Office said.

A yellow weather warning for rain is also in place which covers central and southern parts of the UK stretching from Brigg in North Lincolnshire to Weymouth in Dorset and Canterbury in the South East.

People in those areas have been warned of heavy rain and a small chance of flooding and disruption.
