Heavy rain from tropical cyclones may last for a few days and subsequent landslips and flooding sometimes cause considerably more damage than the winds. However, it seems JavaScript is either disabled or not supported by your browser. Under the influence of stronger-than-normal northeast monsoon, normal to below-normal rainfall in Hong Kong is more likely for this winter. The Observatory adopts an ensemble approach to formulate its seasonal forecast for Hong Kong, taking into consideration available products from major climate prediction centres and the. The situation is likely to develop into a La Niña event. The mean annual rainfall ranges from about 1400 millimetres at Ping Chau to more than 3000 millimetres in the vicinity of Tai Mo Shan. Use of Location-based Rain and Lightning Forecast notification, and Location-specific Heavy Rain notification will increase the battery usage and data download slightly. Due to the above limitations, the rainfall forecast maps and time series may be different from the weather information disseminated by the Hong Kong Observatory and the neighbouring meteorological authorities. Annual rainfall in Hong Kong. The Hong Kong Observatory (HKO) has been operating its nowcasting services since 1999. Station Grid. In this connection, HKO has developed a suite of nowcasting systems, including the "Short-range Warning of Intense Rainstorms in Localized Systems" (SWIRLS), to aid rainstorm warning operation as well as high-impact weather forecasting for the public and the aviation community. The majority of climate models around the world forecast stronger-than-normal northeast monsoon over southern China this winter and hence normal to below-normal temperature for the south China coast.
