Bulletin updated at 00:00 HKT 14/Oct/2017

Here is the latest weather bulletin issued by the Hong Kong Observatory.

A dry northeast monsoon affected the coast of Guangdong yesterday. Locally, it was mainly fine and dry. Under the combined effect of Tropical Storm Khanun and the northeast monsoon, it will be windy with heavy rain over the south China coastal areas in the next couple of days.

At 11 p.m. last night, Khanun was centred about 430 kilometres south-southeast of Dongsha. It is forecast to move west at about 10 kilometres per hour across the South China Sea and intensify. It will move in the general direction of Hainan Island to Leizhou Peninsula.

Weather forecast for Hong Kong (Saturday, 14 Oct 2017)

Mainly fine and dry at first. Becoming cloudy with a few rain patches and there will be swells later. Temperatures will range between 24 and 29 degrees. Fresh north to northeasterly winds, occasionally strong offshore and on high ground.

Outlook : Windy with heavy squally showers in the following couple of days. Weather will improve midweek next week.


(The above forecast period is valid up to 23:59 HKT today, 14/10/2017; Regular update at : around 45 minutes past each hour, 16:15 HKT and 23:15 HKT)

    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.
