The Hong Kong Observatory's tropical cyclone warnings for shipping are issued about two hours after the time of observation. They incorporate additional information derived from surface and upper-air data and may therefore be slightly different from the real-time satellite or radar-based positions given in the hourly bulletins for public. Average errors in the 24, 48 and 72-hour forecast positions are of the order of 150, 250 and 350 kilometres respectively.
