Homes were damaged following reports of a tornado in east London.
Footage shared on social media showed collapsed garden walls, bricks scattered across driveways and fallen branches scattered across the street in Barking on Friday.
Police said they were called around 7:20 p.m. to report damage to roofs, electrical equipment and vehicles in the Hulse Avenue area.
The Metropolitan Police in Barking and Dagenham Twitter account said: “This is a weather-related incident which resulted in a lightning strike.
“In addition to the lightning strike, we have seen reports of a tornado but cannot confirm this.
“There are no reports of victims. The officers are in contact with the local authority to ensure that assistance is available to anyone affected by property damage.
Barking and the Dagenham Council tweeted, “We are aware of the storm damage in the Barking area and our emergency response team, along with the police and fire brigade, are on hand to resolve any issues.”
Met Office forecaster Matthew Box said, “A brief tornado is likely to have occurred.”
A number of meteorological conditions are required to create a tornado, including a cloud funnel reaching the ground, and these various factors have not been confirmed by experts.
Mr Box said: “The associated thunderstorms resulted in very heavy and heavy rains over parts of north and east London and Essex, which resulted in flooding and travel disruptions.”
In some places it is likely that there was more than 40mm of rainfall in an hour.
Mr. Box added that none of the Met Office locations recorded the wind associated with the event, mainly because “it was relatively small”.
He said, “The winds were very noxious for those affected.”
The Met Office had issued a yellow thunderstorm warning on Friday evening, which expired at 11 p.m.
There are an average of around 35 tornadoes in the UK each year, potentially covering “tens to hundreds of meters” and not as large as you might find in the US, Mr. Box said.
