Hong Kong's Leisure and Cultural Services Department announced on September 23 that red flags had been hoisted at several beaches because of big waves, advising beachgoers not to swim at these sites.

The affected beaches are Stanley Main Beach, Shek O Beach and Big Wave Bay Beach in the Southern District on Hong Kong Island, and Clear Water Bay Second Beach in Sai Kung District.

The department issued the notice as an item of interest to swimmers and asked television and radio announcers to broadcast it as soon as possible. The red flags indicate that swimming at these beaches is not advised while the conditions persist.
