Here is the latest Tropical Cyclone Bulletin issued by the Hong Kong Observatory.

The Standby Signal, No. 1 is in force.

This means that a tropical cyclone now centred within about 800 kilometres of Hong Kong may affect us.

At 11 p.m., Tropical Storm Lionrock was estimated to be about 190 kilometres north-northeast of Hong Kong (near 23.9 degrees north 114.8 degrees east) and is forecast to move west at about 18 kilometres per hour crossing inland Guangdong.

On its present track, Tropical Storm Lionrock is expected to maintain a distance of about 200 kilometres from Hong Kong. The chance of Strong Wind Signal Number 3 is not high.

(Precautionary Announcements with No. 1 Signal)

1. Some precautions against damage should be taken now, gutters and drains should be cleared of obstructions. Hinges, bolts, locks and shutters of windows and doors should be checked.

2. Those who have definite duties during a tropical cyclone should now remain on call or contact their control centres from time to time.

4. Listen to radio, watch TV or browse the Hong Kong Observatory's web site for information on the tropical cyclone.
