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

Tropical Cyclone Bailu weakened into an area of low pressure over inland Guangdong yesterday morning. The outer rainbands associated with its remnant affected the coast of Guangdong yesterday. Locally, it was mainly cloudy with occasional showers and squally thunderstorms. Showers were heavy at first. More than 100 millimetres of rainfall were recorded over many places, and rainfall even exceeded 150 millimetres in the urban areas and parts of New Territories East. With an anticyclone aloft strengthening, the weather will improve gradually over southern China today and tomorrow. It will be very hot midweek this week. Besides, the area of low pressure over the western North Pacific intensified gradually yesterday. A tropical cyclone appeared to be forming.

Weather forecast for Hong Kong

Mainly cloudy with a few showers. Isolated thunderstorms at first. Sunny periods during the day. Temperatures will range between 27 to 32 degrees. Moderate south to southeasterly winds.

Outlook : Mainly fine and very hot in the following couple of days. The weather will become unsettled towards the weekend.

Yesterday's (26 Aug 2019) average ambient gamma radiation
dose rate taken outdoors in Hong Kong ranged from 0.09 to

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 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.
