Amber / Red lightning Warning Signals at HKIA
Hong Kong International Airport is equipped with the Airport Lightning Warning System to safeguard the safety of personnel on the apron. An Amber Lightning Warning is issued when lightning is detected within a five-kilometre radius from the airport island and intense radar echo within 15 kilometres from the island, and all non-essential activities in open areas will be suspended. Meanwhile, a Red Lightning Warning is issued when lightning is detected within a one-kilometre domain surrounding the airport island. When the Red Lightning Warning is hoisted, all ramp activities will stop immediately. Participants should follow the instructions given by the race officials at the Event venue.
