Hong Kong experienced extreme weather on June 18 as the Hong Kong Observatory issued a black rainstorm warning for the second time in a single day. The second warning was issued at 6:35 pm, following an earlier warning at noon that lasted approximately two hours and caused flooding in parts of the Northern District, Yuen Long, and Tuen Mun.
The heavy rainfall led to flooding at the Man Kam To control point, with the Shenzhen authorities notifying the Hong Kong government that some facilities at the checkpoint were inundated. As a result, passenger and cargo clearance services at the Man Kam To border crossing have been suspended until further notice.
The double issuance of the black rainstorm warning highlights the severity of the rainstorm, which brought significant disruption to transportation and daily life in affected areas. Residents were advised to stay indoors and avoid low-lying areas prone to flooding.
Local authorities are closely monitoring the situation and coordinating response efforts to minimize the impact of the severe weather. The public has been urged to remain vigilant and follow safety instructions from officials.
Why This Matters
This double black rainstorm warning signals an unusually severe weather event that has shut down a key border checkpoint, directly disrupting cross-border travel and cargo flow between Hong Kong and mainland China. Readers should check the latest transport and clearance status before any planned travel or shipments.
