Hong Kong's heaviest rain in at least 140 years floods city streets, metro

Torrential rain deluged Hong Kong, leading to widespread flooding across the densely packed city, as the weather bureau issued the highest “black” rainstorm warning

Torrential rain deluged Hong Kong on September 8, leading to widespread flooding across the densely packed city, submerging streets, shopping malls and metro stations, as authorities shut schools and asked workers to stay at home.

The Chinese special administrative region saw the highest hourly rainfall since records began 140 years ago.

Hong Kong Observatory reported rainfall of 158.1 millimetres (6.2 inches) between 11 p.m. HKT on Thursday and midnight on Friday (1500 to 1600 GMT on Thursday).

The weather bureau issued the highest "black" rainstorm warning and said more than 200 mm of rainfall was recorded on Hong Kong's main island, Kowloon and the northeastern part of the city's New Territories since Thursday night.

The trough of low pressure associated with the remnant of Typhoon Haikui has brought torrential rain to the coast of Guangdong since Thursday, the weather bureau said. Extreme conditions are expected to last until at least noon on Friday.

Hong Kong's stock exchange will not open on Friday morning if the black rainstorm warning is still in place at 9 a.m., the exchange said.

City leader John Lee said he was very concerned about the severe flooding in most parts of the territory and had instructed all departments to respond with "all-out efforts".
