Urgent flood warning issued by London Fire Brigade as thunderstorms hit the capital
“Firefighters know what they need to do in a flood, but it’s important Londoners know as well.”
It’s set to be a washout day here in London, with hours of torrential rain and thunderstorms on their way.


The Met Office has issued a yellow thunderstorm warning for the capital, and forecasts and showing significant downpours over the next 12 hours.
London Fire Brigade has issued some urgent advice to Londoners, warning them to expect potential flooding.
A London Fire Brigade spokesperson said: “With a thunderstorm warning in place for Thursday, we’re encouraging Londoners to familiarise themselves with what to do in case of a flood.
“The warmer weather we have been having will dry out and crack soil. This makes it harder to absorb and soak up a sudden and heavy downpour. Couple this with torrential rain and we could see streets and homes flooded.
“Our firefighters know what they need to do in a flood, but it’s important Londoners know as well and follow our flooding advice.”
