The Hong Kong Observatory has issued a black rainstorm warning today, the second time this week. Heavy rain, exceeding 70mm per hour, has fallen or is expected to fall across the region. The Home Affairs Department has activated its emergency coordination centre. Temporary shelters have been opened for those in need.
Due to the storm, several public services have been suspended. General outpatient clinics and specialist clinics are closed. Schools have cancelled afternoon classes. Hong Kong Wetland Park is shut, and people are advised not to visit country parks.
This follows the first black rainstorm warning of the year issued on July 29. The warning signals continuous heavy rainfall in the region.
Triggered by a strong low-pressure trough, the downpour has been especially intense on Lamma Island, where hourly precipitation surpassed 100 mm.
In response, the Hong Kong Special Administrative Region (HKSAR) government activated its Emergency Coordination Centre and opened temporary shelters. Public services, including outpatient clinics and schools, have been suspended, and residents are advised to avoid country parks.
This latest alert follows a similar warning issued on July 29, marking a period of severe weather across East Asia. In Beijing, torrential rains have claimed at least 30 lives, mostly in the mountainous districts of Miyun and Yanqing.
Over 80,000 people have been relocated, with rainfall in Miyun reaching 543.4 mm. The storms have damaged roads, disrupted power in over 130 villages, and highlighted the growing impact of extreme convective weather driven by subtropical moisture.
