    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 Warnings

    Bulletin issued at 10:55 HKT 14/Oct/2017

    Tropical Cyclone Warning Bulletin

    Here is the latest Tropical Cyclone Warning Bulletin issued by the Hong Kong Observatory.

    The Standby Signal, No. 1 was issued at 10:40 a.m.

    This means that a tropical cyclone now centred within about 800 kilometres of Hong Kong may affect us.

    At 11 a.m., Severe Tropical Storm Khanun was estimated to be about 700 kilometres southeast of Hong Kong (near 17.3 degrees north 118.3 degrees east) and is forecast to move northwest at about 15 kilometres per hour across the South China Sea and intensify. It will move in the general direction of Hainan Island to Leizhou Peninsula.

    Khanun was relatively slow moving this morning but there is indication that it will take on a more northwesterly track. Under the combined effect of Khanun and the northeast monsoon, winds over Hong Kong will be occasionally strong offshore and on high ground during the day. With Khanun moving closer, local winds will start to strengthen tonight. The Observatory will consider issuing the Strong Wind Signal, No.3 later today, taking into consideration the movement and development of Khanun.

    Khanun is expected to edge closer to the south China coast tomorrow. Local weather will deteriorate significantly. Members of the public should take precautionary measures against high winds and flooding as soon as possible.

    (Precautionary Announcements with No. 1 Signal)

    1. Some precautions against damage should be taken now, gutters and drains should be cleared of obstructions. Hinges, bolts, locks and shutters of windows and doors should be checked.

    2. People living in wooden huts and in low-lying areas should take necessary precautions against strong winds and flooding.

    3. If you are planning to visit Guangdong, Macau, any of the off-shore islands or remote parts of Hong Kong, you are reminded that changes in weather may affect your plans.

    4. Since there may be swells, you are advised to stay away from the shoreline and not to engage in water sports.

    5. Engineers, architects and contractors should make sure that scaffoldings, hoardings and other temporary structures are secured.

    6. Those who have definite duties during a tropical cyclone should now remain on call or contact their control centres from time to time.

    7. Listen to radio, watch TV or browse the Hong Kong Observatory's web site for information on the tropical cyclone.

    Bulletin issued at 09:30 HKT 14/Oct/2017


    Tropical Cyclone Warning

    At 140000 UTC, Severe Tropical Storm Khanun (1720) with central pressure 980 hectopascals was centred within 60 nautical miles of one seven point one degrees north (17.1 N) one one eight point three degrees east (118.3 E) and is forecast to move west at about 5 knots for the next 24 hours.

    Maximum winds near the centre are estimated to be 55 knots.

    Radius of over 33 knot winds 120 nautical miles over northern semicircle, 60 nautical miles elsewhere.
    Radius of over 47 knot winds 30 nautical miles.
    Radius of over 2 metre waves 240 nautical miles.

    Forecast position and intensity at 150000 UTC
    One nine point zero degrees north (19.0 N)
    One one four point nine degrees east (114.9 E)
    Maximum winds 65 knots.

    Forecast position and intensity at 160000 UTC
    Two zero point zero degrees north (20.0 N)
    One one zero point two degrees east (110.2 E)
    Maximum winds 65 knots.

    Forecast position and intensity at 170000 UTC
    One nine point one degrees north (19.1 N)
    One zero seven point two degrees east (107.2 E)
    Maximum winds 35 knots.

    Forecast position and intensity at 180000 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

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.
