Typhoon Ragasa Leaves Hong Kong Reeling With Flooding, Injuries, and Flight Chaos
Hong Kong, a city legendary for its resilience, was brought to a near standstill this week as Super Typhoon Ragasa skirted the financial hub. Despite the storm's center passing over 100 kilometers away, the city was battered by hurricane-force winds and a devastating storm surge, forcing authorities to hoist the ultimate warning: Signal No. 10.
The storm’s impact was historic. The Hong Kong Observatory maintained the Hurricane Signal No. 10 for approximately 10 hours and 40 minutes, marking it as the second-longest duration of the top alert since World War II. Ragasa also made meteorological history by becoming one of the most distant typhoons on record to necessitate the Signal No. 10, underscoring the growing threat posed by storms with exceptionally wide and intense wind fields.
The City Under Siege: Chaos and Damage
The Super Typhoon’s extensive radius translated into widespread infrastructural disruption:
- Human Toll: Over 100 people were reported injured, primarily by flying debris and shattered glass, with nearly a thousand residents seeking refuge in government shelters.
- Coastal Breach: The storm surge was a major threat, with colossal waves overtopping coastal defenses. Dramatic footage showed water smashing through glass doors and flooding the lobbies of seaside properties, notably in areas like Ocean Park and Heng Fa Chuen.
- Air Traffic Gridlock: Hong Kong International Airport, a crucial global transit hub, was paralyzed for over 36 hours. Hundreds of passenger flights were cancelled, stranding thousands and setting off a complex, multi-day backlog that gripped the regional air network.
- Urban Scars: Across the territory, cleanup crews faced a mountain of work: roads were choked by thousands of fallen trees, and multiple reports of slope failures and damaged retaining walls particularly in districts like Sai Ying Pun and Stanley, raised immediate concerns about geotechnical stability.
The Resilience Paradox: Lessons Learned and Vulnerabilities Exposed
The city’s official response was swift and proactive. Authorities were credited with limiting casualties by issuing early, forceful warnings, deploying flood barriers, and suspending schools and public transport well in advance, a clear application of lessons learned from the devastating Super Typhoon Mangkhut in 2018.
However, Ragasa was a harsh stress test that exposed critical weaknesses:
- Coastal Defenses: The sheer power of the storm surge demonstrated that Hong Kong's current seawalls and flood-prone infrastructure remain vulnerable to rising sea levels and intensifying storms.
- Urban Planning: The high incidence of landslides, even from a near-miss, places renewed scrutiny on slope management and building codes in a densely packed, mountainous city.
The Climate Change Mandate
As flights resume and the massive clean-up operation moves forward, Ragasa serves as a powerful, unavoidable warning. Experts globally are unanimous: rising ocean temperatures, driven by climate change, are fueling the rapid intensification and immense size of storms like Ragasa.
The true cost will not just be measured in dollars spent on debris removal and infrastructure repair, but in the political will to adapt. The international community, and the people of Hong Kong, will be watching for the government to urgently overhaul coastal flood defenses, review building resilience standards, and integrate a far more aggressive climate adaptation strategy to prepare for the stronger, more erratic typhoons of the future.
