It comes as the Met Office has a yellow weather warning for thunderstorms covering vast swathes of the UK as forecasters expect more heavy rain and potential disruption.
It said up to 60mm of rain could fall inside three hours in some places as showers and thunderstorms develop into Wales and northern and central England.
A thunderstorm warning runs until 6am on Wednesday.
Ten flood alerts are still in place in England, six of them inside the M25.
It's not over:

That sounds to me as if there'll be terrible floods in the places where there have been many before, like parts of Yorkshire.
