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

Showers continued to affect the coast of Guangdong yesterday. Locally, it was mainly cloudy with a few showers. The weather was hot with sunny intervals during the day. About 30 millimetres of rainfall were recorded over parts of Lantau Island. Besides, a trough of low pressure formed over central China last night, and moved southwards gradually. The trough of low pressure is expected to bring heavy rain and squally thunderstorms to southern China today and tomorrow.

Weather forecast for Hong Kong

Cloudy with showers and squally thunderstorms. Showers will be heavy at times later. Temperatures will range between 24 and 27 degrees. Moderate southerly winds, fresh at times later.

Outlook : Heavy showers at first on Tuesday. Weather improving later. Sunny periods in the following couple of days.


(The above forecast period is valid up to 23:59 HKT today, 15/05/2017; Regular update at : around 45 minutes past each hour, 16:15 HKT and 23:15 HKT)

Yesterday's (14 May 2017) average ambient gamma radiation
dose rate taken outdoors in Hong Kong ranged from 0.08 to
0.14 microsievert per hour.  These are within the normal
range of fluctuation of the background radiation level in
Hong Kong (see Note). The average dose rates measured at the
radiation monitoring stations over various parts of the
territory were as follows :

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.
