When higher signals are up, the Royal Observatory will issue these
bulletins day and night. They will be broadcast at the 30th and 58th minutes
of the hour by radio stations which will usually remain on air throughout
the night.
Under the new format of local warning bulletins now in use, general
information that can be easily understood by the man in the street is contained
in the first half of the bulletins, with more technical details in the second.
Apart from change of signals and their respective meaning, the
bulletins also indicate the intensity of the tropical cyclone, its latest
position and movement. The trend of the tropical cyclone's movement and its
likely effects on Hong Kong are also shown.
Whenever possible, the bulletins will point out the wind force near
the centre of the tropical cyclone, the average wind speed and gust speed
recorded in the harbour and from the coast.
The bulletins also forecast the amount of rainfall which may accompany
the tropical cyclone and the possible tidal change within Hong Kong's waters.
"This information can usually satisfy the general needs of residents
and enable them to decide on necessary precaution," the Director of Royal
Observatory said.
Release time: 2.30 p.m.
