Amber rainstorm warning issued as thunderstorms hit Hong Kong
Heavy rain and 70km/h gusts trigger amber alert, flooding possible
Hong Kong's weather forecaster, the Hong Kong Observatory, issued an amber rainstorm warning on Wednesday, April 29, 2026, at 11:35am, as thunderstorms and intense gusts threatened the city. The alert, which lasted until 12:45pm, was prompted by areas of intense thundery showers associated with upper-air disturbances persistently affecting the region. The Observatory warned that flooding could occur in some low-lying and poorly drained areas, with heavy rain possibly triggering flash floods.
The Observatory also issued a separate thunderstorm warning earlier at 9:20am, noting that intense gusts reaching 70km/h (43.5mph) or above might affect Hong Kong. The public was advised to seek safe shelter during the alert. The amber rainstorm signal, the second-highest in Hong Kong's three-tier warning system, indicates heavy rain exceeding 30mm per hour. This event follows recent weather patterns in the region, emphasizing the need for preparedness during the monsoon season.
