Around one square mile in Wembley was flooded up to a depth of approximately one metre.
Six fire engines and about 40 firefighters responded to the flooding in the area, extending from Tokyngton Avenue to Stonebridge Road and Harrow Road.
The crews successfully diverted flood water to prevent further property damage and led around 19 people to safety. Additionally, they rescued a man trapped in a van near Stonebridge Station.
The fire brigade utilised various equipment, including inflatable rescue boats, rigid flood rescue boats, paddles, rigid floating pontoons, and flood barriers, to rescue people trapped by floodwaters and protect properties in such situations.
They also have protective dry suits and boots for their safety during rescue operations in flooded areas.
A London Fire Brigade spokesperson said: “Recent heavy rain has shown how quickly a flash flood can inundate a street.
“Our firefighters know what they need to do in a flood, but it’s important Londoners know as well. We’d encourage you to follow our flooding advice.”
