Black Rainstorm Warning to remain in force until 5pm, 300mm rainfall recorded over HK Island and Sai Kung

The Black Rainstorm Warning Signal will remain in force at least until 5pm, the Observatory said.

More than 100 millimeters of rainfall were generally recorded over the territory, and rainfall even exceeded 300 millimeters over Hong Kong Island, Kowloon and Sai Kung District.

The forecaster said areas of intense thundery showers associated with active southwest monsoon and upper-air disturbances continue to affect Hong Kong and the vicinity of the Pearl River Estuary.

The current rainstorm warning has been hoisted from 5.50am. The forecaster issued another Black rainstorm signal last night at 11.45pm, which was subsequently downgraded to an Amber signal at 3am.

The heavy downpour has caused serious road flooding and traffic congestion across the city, and authorities advised the public to seek safe shelter. 

Heavy rain may also bring flash floods, and flooding may also occur in watercourses.

The weather watchdog said the Emergency Monitoring and Support Centre of the government will continue to monitor the overall situation.
