Notes

  • The symbol low pressure area symbol will be displayed when the tropical cyclone is expected to weaken into a low pressure area or transform into an extratropical low.
  • Past track is in black, forecast track is in red.
  • The accuracies, based on average errors, of the latest analysed and forecast positions are of the order of:

    Analysed Position30 km
    24-hour forecast position150 km
    48-hour forecast position250 km
    72-hour forecast position350 km

  • The centres of the red, blue and grey circles are the forecast positions of the tropical cyclone at different times (as shown at the upper left corner of the figure). The radii of the circles are the respective accuracies.
  • The tropical cyclone track, analysed positions and maximum sustained wind near centre are based on Hong Kong Observatory's tropical cyclone warning for shipping issued eight times a day at 0:30, 3:30, 6:30, 9:30, 12:30, 15:30, 18:30 and 21:30 HKT, about one and a half hours after the time of observation. The analysed positions incorporate additional information derived from surface and upper-air data and may therefore be slightly different from the real-time satellite or radar-based provisional positions given in the hourly bulletins for public. Meanwhile, the webpage will also display other information, including distance and bearing of the tropical cyclone relative to Hong Kong.
  • The past tropical cyclone track, analysed positions and maximum sustained wind near centre may be updated when additional data is received.
  • Short-term erratic departures of the tropical cyclone from the general direction of movement may occur from time to time. These departures are partly due to uncertainties in locating the centre of the tropical cyclone, and partly due to actual short-term variations in the direction and speed of movement of the tropical cyclone itself.
