    Maximum winds near the centre are estimated to be 80 knots.

    Radius of over 33 knot winds 210 nautical miles.
    Radius of over 47 knot winds 120 nautical miles over eastern semicircle, 90 nautical miles elsewhere.
    Radius of over 63 knot winds 45 nautical miles.
    Radius of over 2 metre waves 300 nautical miles.

    Forecast position and intensity at 011500 UTC
    Two nine point six degrees north (29.6 N)
    One two two point three degrees east (122.3 E)
    Maximum winds 65 knots.

    Forecast position and intensity at 021500 UTC
    Three three point nine degrees north (33.9 N)
    One two five point four degrees east (125.4 E)
    Maximum winds 50 knots.

    Forecast position and intensity at 031500 UTC
    Three six point three degrees north (36.3 N)
    One three zero point one degrees east (130.1 E)
    Maximum winds 40 knots.

    Forecast position and intensity at 041500 UTC
    Become extratropical low.



    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 in the
past, the hourly mean ambient gamma radiation dose rate may
vary between 0.06 and 0.3 microsievert per hour. (1
microsievert = 0.000001 sievert = 0.001 millisievert)

    2. Temporal variations are generally caused by changes in
meteorological conditions such as rainfall, wind and
barometric pressure.

    3. Spatial variations are generally caused by differences in
the radioactive content of local rock and soil.

    4. The data displayed is provisional. Only limited data
validation has been carried out.
