Hong Kong meteorological authorities issued an "amber" rainstorm warning at 15:00 (local time) on Wednesday, June 13. The warning indicates that more than 3 cm (1 in) of rain per hour is anticipated. Thunderstorms are also expected. Localized flooding is possible, particularly in low-lying areas. Associated transportation disruptions are possible throughout the day.
Heavy rain is common in Hong Kong during the western Pacific Ocean typhoon season, which runs from May to October.
Individuals present in Hong Kong are advised to confirm travel reservations, to keep abreast of weather forecasts, and to adhere to any instructions issued by the local authorities. Remember that driving or walking through running water can be dangerous - 15 cm (6 in) of running water is enough to knock over an adult - and that floodwater may contain wastewater or chemical products.
