Bulletin updated at 21:45 HKT 01/Nov/2017

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

The northeast monsoon continues to bring fine weather to southern China.

At 8 p.m., the tropical depression near the Philippines was centred about 590 kilometres east-northeast of Nansha Dao. It is forecast to move west at about 20 kilometres per hour towards the southern part of the South China Sea. Meanwhile, the tropical depression over the seas south of Vietnam was centred about 370 kilometres south of Ho Chi Minh City. It is forecast to move west slowly towards the Gulf of Thailand.

Weather forecast for tonight and tomorrow

Fine. The minimum temperature tomorrow morning will be about 21 degrees in the urban areas, and a couple of degrees lower in the New Territories. Dry during the day with a maximum temperature of around 28 degrees. Moderate northeasterly winds.

Outlook : Becoming cloudy with a few rain patches in the following couple of days.


(The above forecast period is valid up to 23:59 HKT tomorrow, 02/11/2017; 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.
