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) after earlier making landfall in China's Guangdong province and prompted the observatory to issue an amber warning, signifying heavy rain, at 5.20 am Hong Kong time (1720 EDT).
More than 150 flights were canceled, the Airport Authority said, with Cathay Pacific and Dragonair warning none of their flights would be operating until 2 pm (0200 EDT) at the earliest. Hundreds of passengers were stranded at the airport and 290 flights delayed.
Nida was moving gradually to the inland areas of Guangdong and winds near its center had showed signs of weakening, according to the Hong Kong Observatory.
Hong Kong Exchanges and Clearing Limited (HKEX) announced that the morning trading in its securities market, including Shanghai-Hong Kong Stock Connect trading, and derivatives market has been delayed due to the issuance of Typhoon Signal No. 8.
The morning trading session at the Hong Kong stock exchange will be suspended if the typhoon signal remains at 8 or higher at 9 a.m. local time (2100 EDT). The stock market will be shut for the rest of the day if a typhoon signal 8 is still in place by noon.
Streets were largely deserted and shops shuttered since Monday evening when the typhoon signal 8 was hoisted, prompting many people to leave work early.
Across the border, Guangdong province closed offices, factories and schools on Monday as it braced for Nida.
Last month, Typhoon Nepartak drove at least 420,000 Chinese from their homes and caused more than 7.1 billion yuan ($1.1 billion) in losses in Fujian province alone.
