Where are the floods in London? Latest travel advice as capital is hit by heavy rain

After a comparatively sunny, warm few weeks, this past weekend saw the skies above London open up and drench the city in rain. A little rain is nothing new to Londoners, of course, but the downpour has raised the risk of flooding in some parts of the capital.

The Met Office’s official verdict as of this morning (September 23) is a low overall risk of flooding for London, with the risk reducing to very low as the week goes on. Still, those living on low ground or near a river should take care over the next few days.

Nothing like the great British weather to humble us all in the face of mother nature, eh? Below, find the key info and travel advice you need to know.
