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.
