Flood warnings have been issued as thunderstorms and torrential downpours look set to replace the sunshine over the rest of the bank holiday weekend.

The Met Office is warning of a risk of flooding to homes and businesses in the south of England, with possible damage to buildings from lightning strikes or strong winds.

A yellow weather warning is in place until Monday morning.

However, temperatures are forecast to remain unseasonably high and could still reach up to 29C on Sunday in some places.

Forecasts suggest it will be warm and humid in London and the South East over the remainder of the long weekend.

Met Office meteorologist Sarah Kent said: "It is going to be warm and I think nearly everybody will see some sunshine, but the big caveat is that because it's been quite humid, particularly southern parts are at risk of seeing some quite heavy showers.

"It could possibly develop into some heavy thundery outbreaks over the next 48 hours."

Despite the "quite torrential" showers, Ms Kent said temperatures are set to reach 24C in the south while Glasgow could be as high as 22C on Sunday.

Ms Kent warned the rain could affect drivers over the holiday weekend, which would add to the disruption from engineering works and industrial action.

Network Rail issued a warning over services to and from Birmingham New Street, no trains stopping at Swindon and bus replacements between Oxenholme and Glasgow Central and Edinburgh due to rail improvements.
