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

A fresh easterly airstream affected the coastal areas of Guangdong today. Locally, it was mainly cloudy. There were one or two showers in the morning and sunny intervals in the afternoon. Temperatures over the territory around noon were generally three to four degrees lower than those of yesterday. Under the influence of a trough of low pressure, there will be showers over southern China in the next couple of days.

Weather forecast for Hong Kong (Monday, 8 May 2017)

Mainly cloudy. Sunny intervals during the day. There will be a few showers and thunderstorms later. Temperatures will range between 24 and 29 degrees. Moderate easterly winds.

Outlook : Sunny intervals and a few showers on Tuesday. Mainly fine and hot during the day in the following couple of days.

Yesterday's (06 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.
