Travellers woke on 22 May to scenes more reminiscent of a typhoon than late-spring showers after the Hong Kong Observatory hoisted a red rainstorm warning at 02:40. The alarm – the territory’s second-highest – signalled that more than 50 mm of rain had fallen or was expected within an hour, triggering automatic school closures and advice for employers to adopt flexible work arrangements. The deluge quickly overwhelmed drainage systems in parts of the New Territories and low-lying pockets of Kowloon. Bus operators diverted dozens of routes, green and red minibuses curtailed hill services and some cross-harbour tunnels saw congestion reach two hours. MTR trains continued running but at reduced speeds through exposed sections, leading to platform crowding. Hong Kong International Airport remained open, yet airlines warned passengers of knock-on delays as aircraft threaded around storm cells on approach. Airport buses A33X and A41 detoured around flooded sections of Tolo and Fanling Highways, adding up to 45 minutes to journeys. Outlying-island ferries and harbour services operated skeleton timetables when visibility fell below 200 m. For companies managing regional assignments and critical meetings, the event underscored the importance of robust travel-risk policies that account for Hong Kong’s increasingly volatile weather. Advisories recommended that expatriates and visiting executives monitor the Observatory’s three-tier rainstorm system, build buffer time into itineraries and review remote-work contingencies during the April–September wet season.
