Hong Kong is often affected by heavy rain every summer. In addition to the widely-recognised Rainstorm Warning Signals, the Observatory may also issue "Announcement on Localised Heavy Rain" when situation warrants. This service will be introduced in the latest episode of "Cool Met Stuff". The video is now available on the "MyObservatory" mobile application and the Observatory's website for your viewing.
