Typhoon Nida swept through Hong Kong on Tuesday, shutting down most of the financial hub with gale-force winds and disrupting hundreds of flights, while low-lying areas were put on flood alert.
Hong Kong's first major typhoon this year brought gusts of more than 100 km per hour (62 miles per hour) and prompted the observatory to issue an amber warning, signifying heavy rain, at 5.20 am Hong Kong time.
More than 150 flights were cancelled, the Airport Authority said, with Cathay Pacific and Dragonair warning none of their flights would be operating until 2 pm (0600 GMT) at the earliest. Hundreds of passengers were stranded at the airport and around 325 flights are expected to be rescheduled.
Ferry, tram and bus services were also suspended.
Streets were largely deserted and shops shuttered since Monday evening when the typhoon signal 8 was hoisted, prompting many people to leave work early.
