Hong Kong warns of water discharge from Shenzhen Reservoir, risk of flooding in the New Territories

Hong Kong has been informed by the Shenzhen Authority that water would be discharged from the Shenzhen reservoir from about midnight, with a possible risk of flooding in some parts of the New Territories, the government announced at 11.44 pm on Thursday.

A government spokesman said various government departments, including District Office (North), Drainage Services, Police, Fire Services, Water Supplies and Social Welfare have been informed in order that they can take any necessary measures.

The District Office (North) is also making arrangements to inform local residents of the appropriate actions to take, the spokesman added.

Meanwhile, the Hong Kong Observatory issued the Black Rainstorm Warning signal at 11.05pm on Thursday, warning that heavy rain – exceeding 70 millimeters an hour – has fallen or is expected to fall generally over Hong Kong.

The forecaster said flooding could be very serious in certain areas, and people should not attempt to travel when the black rainstorm alert is in force.

"Because of seriously flooded roads and inclement weather conditions, you are advised to take shelter in a safe place and stay there," it said.

"Heavy rain will bring flash floods, and flooding is occurring or is expected to occur in watercourses. People should stay away from watercourses. Residents living in close proximity to rivers should stay alert to weather conditions and should consider evacuation if their homes may become flooded."

The sudden downpours caused flash flooding across the city, with areas like Chai Wan, Tai Po, Fanling and Sheung Shui being the worst affected.

The MTR Corporation said the exits of some of its stations might be temporarily closed due to flooding.

The rail giant also announced at 12.30 am on Friday that the Kwun Tong Line service was disrupted due to flooding in section near Wong Tai Sin Station. Trains between Whampoa Station and Kwun Tong Station are suspended, while trains between Kwun Tong Station and Tiu Keng Leng Station have to operate at 12-minute intervals.
