    Tropical Cyclone Warning

    At 020300 UTC, Tropical Storm Damrey (1723) with central pressure 998 hectopascals was centred within 90 nautical miles of one two point five degrees north (12.5 N) one one six point eight degrees east (116.8 E) and is forecast to move west at about 10 knots for the next 24 hours.

    Maximum winds near the centre are estimated to be 35 knots.

    Radius of over 33 knot winds 30 nautical miles.
    Radius of over 2 metre waves 90 nautical miles.

    Forecast position and intensity at 030300 UTC
    One two point zero degrees north (12.0 N)
    One one three point one degrees east (113.1 E)
    Maximum winds 50 knots.

    Forecast position and intensity at 040300 UTC
    One one point eight degrees north (11.8 N)
    One zero nine point four degrees east (109.4 E)
    Maximum winds 60 knots.

    Forecast position and intensity at 050300 UTC
    Dissipated over land.



    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.
