Hong Kong's weather bureau said its highest "black" rainstorm warning would remain in place until 11 a.m. on Tuesday, as heavy rains lashed the Asian financial hub, closing hospital wards, schools, and the jurisdiction's courts and register offices.

Hong Kong was hit by its heaviest August rain since 1884, flooding streets, closing services, and breaking records amid broader climate-related chaos in China.

Widespread flooding has hit the city as the Hong Kong Observatory (HKO) issued the black rainstorm warning on Tuesday – the first time the highest rainstorm signal was hoisted three times within a week.
