Notes
- The symbol
 will be displayed when the tropical cyclone is expected to weaken into a low pressure area.
- Past track is in black, forecast track is in red.
- The average errors of the analysed and forecast positions are of the order of:
| Analysed Position | 30 km |
| 24-hour forecast position | 150 km |
| 48-hour forecast position | 250 km |
| 72-hour forecast position | 350 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 average forecast errors.
- The past tropical cyclone track and re-analyzed tropical cyclone (the symbol
 ) / low pressure area positions are based on Hong Kong Observatory's tropical cyclone warning for shipping 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 provisional positions given in the hourly bulletins for public.
- Short term erratic departures from the general direction of movement occur from time to time. These departures are partly due to difficulties in locating the centre of the tropical cyclone / low pressure area, and partly due to short term fluctuations in the direction and speed of movement of the centre.
