Persistent heavy rain on Wednesday caused widespread disruption in the Chinese capital, Beijing, forcing the delay and cancellation of hundreds of flights and the closure of some subway stations.
Pictures on social media showed cars making their way slowly through flooded streets in parts of the city.
Some high speed rail services were also delayed, the rail authority said.
There were no reports of any casualties.
Beijing’s steamy summer months are often marked by dramatic rainstorms, one of which in 2012 killed 37 people.
