Track and Positions of Tropical Cyclones

There is currently no tropical cyclone located within the area bounded by 7-36N and 100-140E.*




* (1) Within the area bounded by 7-36N and 100-140E but outside the area bounded by 10-30N and 105-125E, when there is an area of low pressure intensified into a tropical cyclone or a tropical cyclone has entered this area, the Observatory will issue the information of tropical cyclone track, analysed positions and maximum sustained wind near centre within two hours. The positions at 8 a.m. and 8 p.m. and 72-hour forecast tracks will be updated twice daily at around 10 a.m. and 10 p.m. respectively. 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) Tropical cyclone warnings for shipping will be issued by the Observatory for tropical cyclones located within the area bounded by 10-30N and 105-125E. The forecast tracks for these tropical cyclones will be updated at 3-hourly intervals.
