Hong Kong was hammered by 12.5 hours of torrential rain between the night of 21 May and the morning of 22 May, prompting the Hong Kong Observatory to hoist its first Red Rainstorm Warning of the year. Rainfall exceeded 300 mm in the northern New Territories, flooding sections of the Fanling and Tolo Highways and submerging parts of Lung Yeuk Tau and Kwu Tung. Local media published images of Kowloon Motor Bus vehicles with ankle-deep water on board and taxis stalled under viaducts. Airport bus routes A33X and A41 were diverted, adding up to 45 minutes to what is normally a 40-minute run to Hong Kong International Airport.

Travelers and corporate mobility planners whose itineraries are suddenly rerouted by severe weather can lean on VisaHQ’s Hong Kong team (https://www.visahq.com/hong-kong/) for rapid visa amendments, transit-permit solutions, and real-time advice on evolving entry rules, helping staff and cargo escorts stay compliant even when flight schedules shift without warning.
The Drainage Services Department confirmed seven flood reports and deployed its new robotic high-capacity “water-dragon” pumps, clearing the worst black-spots by mid-morning. For employers the main headache was commuting: East Rail and Tuen Ma Line speeds were reduced, and staff who live in border towns reported two-hour journeys to Central. Mobility and crisis-management teams should revisit wet-weather contingency plans—especially for airport transfers and cross-border trucking through Sheung Shui and Lok Ma Chau, where low-lying roads are prone to flash floods. Meteorologists warn that May-June is Hong Kong’s peak for cloud-burst events. Companies with supply-chain dependencies on just-in-time road freight or perishable air cargo should build extra buffer days and monitor the Observatory’s Rainstorm Signal API in real time.
