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.

Bulletin issued at 18:30 HKT 08/Jun/2018


Tropical Cyclone Warning

At 080900 UTC, Tropical Depression Ewiniar (1804) with central pressure 996 hectopascals was centred within 90 nautical miles of two three point three degrees north (23.3 N) one one two point five degrees east (112.5 E) and is forecast to move north or north-northeast slowly for the next 24 hours.

Maximum winds near the centre are estimated to be 30 knots.

Radius of over 2 metre waves 90 nautical miles.

No further warnings on this Tropical Depression will be issued by the Hong Kong Observatory unless re-intensification takes place.

Forecast position and intensity at 090900 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 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.
