Hong Kong and multiple cities in southern China are facing severe flooding due to the heaviest rains in over 140 years. Streets and subway stations in Hong Kong were inundated, leading to school and workplace closures. More than 100 people were hospitalized, and several rescues were carried out. A black weather warning was issued as streets turned into raging rivers, flooding shopping centers and public transport. Authorities issued the black warning after rainfall exceeded 70mm per hour, and Hong Kong Observatory reported an hourly rainfall of 158.1 millimeters, the highest on record since 1884. The city’s cross-harbor tunnel was flooded, and landslides occurred in mountainous areas, blocking highways. While rain has eased and the warning was downgraded to amber, showers are expected to persist until Saturday. Southern China, including Shenzhen, reported its heaviest rainfall since records began in 1952. Hundreds of flights were suspended, and local authorities advised residents in low-lying areas to consider evacuations. China’s meteorological administration expects continued extreme rainfall in the region. This flooding comes shortly after two typhoons, Saola and Haikui, struck southern China.
