Passengers look at an information board displaying a list of cancelled and delayed flights in Hong Kong on August 1, 2016, shortly after a 'T8' storm signal was raised for Typhoon Nida.

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.
