Hong Kong on Monday recorded eight reports of flooding as the city was hit by another downpour that saw an hourly rainfall of over 100 millimeters in the city’s Sai Kung district, swamping villages, roads, cars and schools.

In response, the Drainage Services Department (DSD) deployed 15 emergency teams who swiftly brought the situation under control, clearing flooded roads and unblocking drains.

The heavy rainfall was a double whammy for the city, which was still reeling from a record-breaking rainstorm that battered the city on Thursday and Friday, bringing Hong Kong to a virtual standstill

In a follow-up press briefing on Monday afternoon, a DSD official said the flooding was mostly caused by branches, leaves, and other debris that blocked drains and catchment areas.

Lau Kai-hong, chairman of the Hang Hau Rural Committee, said that he was in the village when the flood struck. During the heaviest rainfall in the morning, most of the houses were flooded, with water levels reaching knee-height, he said.

He said  that the impact of this flooding was more severe than that of Typhoon Saola  and last Friday’s rainstorm, as many villagers were at work during the storm and were unable to take adequate precautions.
