A petrol station has been left seriously damaged after strong winds caused a tree to collapse onto its forecourt.
Pictures show how the roof of a Shell garage in Mottingham, southeast London, caved-in and sent debris flying.
Members from the London Fire Brigade were called to deal with the incident on the A20 Sidcup Road earlier this afternoon.
It is understood that no one was injured following the incident which has caused significant traffic delays.
Transport for London tweeted: “The A20 Sidcup Road (SE9) at the junction of Court Road.
“Emergency services incident with London Fire Brigade attending at location on the southbound carriageway and delays are possible.”
The incident happened after the Met Office issued an urgent storm warning for parts of the country this afternoon .
The yellow alert, issued just before 3pm, is for thunderstorms across the north, parts of Scotland and Devon and Cornwall.
The new warning follows three issued by the Met Office for Friday and Saturday – warning of high winds and heavy rain.
Those warnings saw major events cancelled across Devon and Cornwall – including Boardmasters in Newquay.
The new warning reads: “Heavy showers and thunderstorms are expected on Sunday afternoon and early evening.
“Some places will miss these, but where they do occur, 20mm rainfall is possible in less than an hour and 30-40mm in two to three hours in one or two spots.
“Lightning and hail may be additional hazards. The showers will slowly die out through the evening.”
In areas such as Glasgow, Edinburgh and Perth heavy rain is possible, with the potential for it to lead to travel disruption and flooding in a few places.
While heavy rain is affecting parts of northern England – including Newcastle upon Tyne – and may lead to some flooding and disruption.
The Met Office added: “Spray and flooding could lead to difficult driving conditions and some road closures.
“Bus and train services probably affected with journey times taking longer. Flooding of a few homes and businesses is possible.”
Tomorrow, the rain will die out over northern England. Elsewhere, there will be a mixture of sunny spells and scattered showers.
The showers will be heaviest in the northwest, but also across southeast England at first.
From Tuesday to Thursday the weather will stay unsettled, with sunny spells and showers on most days.
Some longer spells of rain are likely on Wednesday, especially in the south. Temperatures will stay a little below normal.
Meanwhile, more than 70mm of rain fell in Cumbria yesterday as the country was struck by unseasonable heavy rain and strong winds.
The Met Office said the wettest part of the country was Spadeadam where 71.4mm fell – compared to a monthly average of 82.4mm for August in the region.
Metereologist Helen Roberts said: “It does look like remaining unsettled and changeable right through most of the next seven days.”
She added that strong winds on Saturday – which saw ferry passengers heading to Dover delayed by up to five hours owing to choppy seas – would be largely absent today, but rain and heavy showers were possible.
On Saturday, flooded tracks forced train operators to cancel services between Cumbria and Scotland in a day of disruption on the rail network.
Flooding between Penrith and Lockerbie forced operators to suspend services on Saturday afternoon.
Network Rail Scotland tweeted images of the rails about a foot under water and said five trains had been trapped between Lockerbie and Carlisle.
There was also flooding between Blackburn and Clitheroe, causing blockages to the lines on Saturday evening.
Earlier today, police in Cumbria urged drivers to take extra care in the weather conditions and only drive if necessary.
Superintendent Justin Bibby said: “If people do have to make journeys we would ask them to be vigilant as to the road conditions and take care.
“We would ask drivers to leave themselves plenty of time for any journeys and to monitor local radio and websites for any travel information.
“If anybody does need to drive, please be aware of your surroundings, drive to the conditions you face and take care.”
