A thunderstorm warning has been issued by the Met Office for much of southern England on Thursday, with the risk of torrential downpours which may cause travel disruption and, in a few places, flooding.

The yellow thunderstorm warning is in place between 10am and 11.59pm.

The Met Office said there was a small chance homes and businesses could be flooded as well as the possibility of fast flowing floodwater causing danger to life.

Flooding could also cause some road closures, with heavy traffic on the roads already expected around the UK due to rail strikes.

Thousands of people heading to Glastonbury Festival, which opened on Wednesday, could bear the brunt of the conditions – with the event being held on the edge of the weather warning area.
