1. Only tropical cyclones centred within the area bounded by 7-36N and 100-140E
( show on map) 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:

*The tropical cyclone track, analysed positions and maximum sustained wind near
centre are based on Hong Kong Observatory's tropical cyclone warning for
shipping.
**When a tropical cyclone forms within or enters this area, the Observatory will
issue the first 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 uncertainty of the tropical
cyclone locations as described below in using this function.
3. 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. By
pressing the 'Potential Track Area' button, the probable area within which the
tropical cyclone will fall with a probability of 70% will be shown. Literally, it means
that in 10 times of track forecast for similar situations, the tropical cyclone will be
centred within the indicated area in about 7 times. The area grows as the forecast
hour increases. It will be particularly larger beyond 72 hours and is indicated with
lighter shadings on the map. The size in terms of radius of the 'Potential Track
Area' corresponding to different forecast hours are determined from the error
statistics of the forecasts issued in past years and are as shown in the following
table:
Analysed position
24-hour forecast position
48-hour forecast position
72-hour forecast position
96-hour forecast position
120-hour forecast position

125 km
225 km
325 km
400 km
500 km

4. 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.
5. 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.
6. 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.
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 fixedarea map version to view the tropical cyclone track directly.
8. The satellite images were originally captured by the Himawari-8 (H8) satellite 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).
