    Bulletin issued at 15:30 HKT 16/Oct/2017


    Tropical Cyclone Warning

    Tropical Depression Khanun (1720) has weakened into an area of low pressure with central pressure 1002 hectopascals. At 160600 UTC, it was centred within 60 nautical miles of two zero point one degrees north (20.1 N) one zero nine point three degrees east (109.3 E).

    Maximum winds near the centre are estimated to be 20 knots.

    No further warnings on this area of low pressure will be issued by the Hong Kong Observatory unless re-intensification takes place.



    The Hong Kong Observatory's tropical cyclone warnings for shipping are issued about one and a half 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 positions given in the hourly bulletins for public.

    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.

Note

      

    1. From readings taken at various locations in Hong Kong during
the period 1987-2016, the background ambient gamma radiation
levels may vary between 0.06 and 0.30 microsievert per hour.

    2. The extent of health effects to a person as a result of
exposure to radiation is expressed by a physical quantity
called equivalent dose, in unit of sievert.  Protective
action may be required if there is an increase in the
ambient gamma dose rate above background such that the total
additional dose is expected to exceed 5000 microsieverts in
a relatively short period of time. For example, a dose of
5000 microsieverts may be reached when the ambient gamma
dose rate is 1000 microsieverts per hour (several thousand
times above background) and lasts for 5 hours.

    3. The readings of ambient gamma radiation level from
instrument are expressed in unit of gray, which is
numerically equal to the gamma dose expressed in sievert.
