    Significant Weather Information (SIGMET)

    The Airport Meteorological Office is responsible for monitoring hazardous weather and phenomena in the atmosphere that may affect the safety of aircraft operations within a designated airspace over the northern part of the South China Sea. Weather forecasters at the Airport Meteorological Office issues SIGMET information when hazardous weather and phenomena in the atmosphere such as thunderstorms, tropical cyclones, turbulence, icing occur or are expected to occur in the airspace.

    Tropical Cyclone Warning

    At 180600 UTC, Tropical Storm Danas (1905) with central pressure 992 hectopascals was centred within 60 nautical miles of two five point six degrees north (25.6 N) one two four point zero degrees east (124.0 E) and is forecast to move north at about 12 knots for the next 24 hours.

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

    Radius of over 33 knot winds 120 nautical miles over eastern semicircle, 60 nautical miles elsewhere.
    Radius of over 2 metre waves 240 nautical miles over eastern semicircle, 180 nautical miles elsewhere.

    Forecast position and intensity at 190600 UTC
    Three zero point one degrees north (30.1 N)
    One two four point four degrees east (124.4 E)
    Maximum winds 40 knots.

    Forecast position and intensity at 200600 UTC
    Three four point four degrees north (34.4 N)
    One two six point three degrees east (126.3 E)
    Maximum winds 35 knots.

    Forecast position and intensity at 210600 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.
