A yellow weather warning has been issued for Merseyside and other parts of the UK as thunderstorms and rain are set to hit after the first official heatwave of the year.
Meteorologists have said people should expect "sudden flooding" which can lead to difficult driving conditions and "some road closures". Forecasters are also warning of potential delays or cancellations to public transport services.
The storms are predicted after a spell of balmy weather in recent weeks.
