SHANGHAI, July 14
For the third time this summer, Shanghai issued its highest alert for extreme heat as temperatures appeared set to test records in China's most populous city on Thursday.
The city of 25 million residents announced a red alert, indicating temperatures were expected to rise to at least 40 Celsius (104 Fahrenheit) over the next 24 hours.
The city has issued three red alerts in the past five days, though it is a relatively rare occurrence as Shanghai has issued 17 such alerts since record-keeping began in 1873.
On Wednesday, the city sweltered as temperatures rose as high as 40.9C, matching a record set in late July, 2017.
