  Notes

 
  1. Only tropical cyclones centred within the area bounded by 7-36N and 100-140E will be shown on this website. According to the analysed position of the tropical cyclone and the tropical cyclone warning signal in force, the update time of this webpage and the information shown will be different. Details are listed in the table below:

    *Within the above area, when there is an area of low pressure intensified into a tropical cyclone or a tropical cyclone has entered this area, the Observatory will first issue the tropical cyclone track within two hours. When the tropical cyclone is expected to enter the area bounded by 10N and 30N, 105E and 125E in about 24 hours, the Observatory will also update the tropical cyclone track at 04:00 and 16:00 Hong Kong time (corresponding to the observation time at 02:00 and 14:00 respectively).

  2. Detailed information of the tropical cyclone, including latitude,longitude,classification and the maximum sustained wind near centre will be shown when placing the mouse cursor over the analysed or forecast positions. The user can use the controls on the left of the map to change the area of interest and to zoom into city or even street levels. Please bear in mind the accuracy of the tropical cyclone locations as described below in using this function.

  3. The region within which the tropical cyclone is more likely to fall and move will be shown by pressing the 'Track Accuracy' button. This is an indication of the accuracy of the forecast track. The accuracies, based on average error, are of the order of:

    Analysed position30 km
    24-hour forecast position150 km
    48-hour forecast position250 km
    72-hour forecast position350 km


  4. The infra-red satellite image closest to the time of tropical cyclone analysed position can be shown by pressing the 'Satellite Image' button, below which is the 'Time of image' representing the time when satellite data is completely received at the ground reception system. Since it takes time to receive and process the satellite data as well as generate the image, the time of image may somtimes be different from the time of tropical cyclone analysed position.

  5. The Hong Kong Observatory's radar images closest to the time of tropical cyclone analysed position can be shown by pressing the 'Radar Image' button, below which is the 'Time of image' representing the time when radar completes its scan. For detailed information, please refer to the Weather Radar Image website.

  6. Short-term erratic departure 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.

  7. The background geographical information in this page comes from Google Maps and the usage is subject to Google's Terms of Use.The downloading speed depends on the responsiveness of its servers and sometimes it may take a longer time to complete the download. In that case, user may consider using the fixed-area map version to view the tropical cyclone track directly.

  8. The satellite images were originally captured by Multi-functional Transport Satellite (MTSAT) of Japan Meteorological Agency (JMA). Anyone wishing to further disseminate these satellite images should seek permission from JMA. (Address: Japan Meteorological Agency, 1-3-4 Ote-machi, Chiyoda-ku, Tokyo 100-8122, Japan).
