The Hong Kong Observatory's tropical cyclone warnings for shipping are issued about one and a half 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.

While the forecast positions and track indicate the most likely future path of the tropical cyclone, they may deviate from the actual path taken by the storm.
