Notes
Only tropical cyclones located within the area bounded by 7-36N and 100-140E will be shown on this website. The past tropical cyclone track and analysed positions may be updated when additional data is received:
When Tropical Cyclone Warning Signal No. 1 or above is in force, the hourly analysed tropical cyclone position will be shown.
When the tropical cyclone is within the area bounded by 10-30N and 105-125E, the tropical cyclone track is updated 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.
When the tropical cyclone is beyond the area bounded by 10-30N and 105-125E but within the area bounded by 7-36N and 100-140E, the tropical cyclone track is updated twice a day at noon and midnight about four hours after the time of observation.
The uncertainties, based on average errors, of the latest analysed position and forecast positions are represented by yellow circles on the map and 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
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.
