On June 18 at 12:55 pm local time (0455 GMT), the Hong Kong Observatory raised weather warning to the black rain signal. The alert forced closure of primary and secondary schools and led many businesses to suspend operations. It is the second black signal in 2026, the first issued on June 8.
Background

The observatory issued a flood announcement for New Territories, highlighting rain in Yuen Long, Sheung Shui and Ta Kwu Ling.
