A huge section of roof on a building in Slough High Street has reportedly been ripped off after strong winds battered the UK.
Footage taken in the High Street shows a large part of a roof in the middle of the road on Tuesday evening.
There are currently no injuries, according to the ambulance service.
Thames Valley Police are on the scene now, the road has been closed and specialists are attempting to make the scene safe.
The fire service said they are currently "not aware of anyone trapped" but are not "100% sure” if anyone was still in the damaged building, which is believed to be both residential and commercial.
A council spokesman urged people to avoid the area and said: "We are aware of the incident in Slough High Street and specialist officers are working with emergency services to ensure safety of debris and buildings and also clear the street."
Videos and images of the ongoing incident have been posted on shocked onlookers on social media. Some clips appear to show a van under the rubble.
While some people were captured walking around the decimated roof and calling for survivors.

Housing firm Paradigm Housing said the incident in Slough had affected one of its properties, although it is unclear whether the roof had come off its building.
In a statement on Twitter the firm said: “We are aware of an incident affecting one of our properties in Slough.
“We have staff on site and are working with the emergency services and supporting residents.
“If you need to contact us please ring 0300 303 1010 where you will be connected to our out of hours provider.”
It comes as Britons were warned of the second storm to hit the country in 24 hours.
Commuters were given prior notice of possible disruptions caused by 70mph winds and heavy rain.
Passengers travelling between Southampton, Bournemouth and Weymouth were warned over disruption, while there were also delays between Penzance and Exeter, and between London and Cambridge, Ely and Kings Lynn.
