4th May 2024 – (Hong Kong) The Hong Kong Observatory issued a Red Rainstorm Warning Signal Special Announcement at 8.55am today, indicating that heavy rain has fallen or is expected to fall across Hong Kong. The rainfall is expected to exceed 50 millimetres per hour and may continue for some time.

The current Red Rainstorm Warning Signal highlights the potential hazards posed by the heavy rain. The downpour could lead to severe road flooding, resulting in traffic congestion and possible disruptions to normal school hours. Parents, students, school authorities, and school-bus drivers are advised to stay informed through radio or television announcements regarding school arrangements. Individuals planning to travel should carefully consider the weather and road conditions and take necessary precautions.

Flash floods are a significant concern during periods of heavy rain, and watercourses are susceptible to flooding. It is crucial for people to stay away from watercourses and exercise caution. Residents living near rivers should remain vigilant and consider evacuation if their homes are at risk of flooding.

In the Tseung Kwan O area, the rainfall has been particularly intense. Within the past two hours, Tseung Kwan O and Clear Water Bay have recorded over 150 millimetres of rainfall. The heavy rain has caused significant issues, including a severe mudslide along the Yung Shue O Road near Chap Fuk Road. This resulted in the erosion of nearby embankments and the deposition of sand and rocks onto the road surface. Authorities have responded by closing affected roads and clearing debris from drainage channels to alleviate water accumulation. In another incident, a retaining wall measuring approximately 6 meters by 9 meters collapsed along Hang Hau Road. Firefighters are currently conducting rescue operations at the scene.

The adverse weather conditions have also led to widespread waterlogging in various areas of Tseung Kwan O. Numerous vehicles have become stranded due to engine failures caused by the inundation. For instance, the open-air car park opposite the Data Centre on Wan Po Road is completely submerged, with water depths reaching approximately 30 centimetres.

In response to the road closures resulting from the flooding along Clear Water Bay Road and Ying Yip Road, Kowloon Motor Bus (KMB) has announced temporary adjustments to routes 91 and 91M. These services will terminate at the Hong Kong University of Science and Technology (HKUST), and the section between Yat Yin Road and Clear Water Bay Road/Po Lam will be temporarily suspended.
