Precautionary Measures when Tropical Cyclone Warning Signals are in force
Introduction
Tropical cyclones normally occur during the months of May to November, and are particularly prevalent during September.
Tropical cyclone advisory bulletins and/or warnings are issued by the Hong Kong observatory whenever a tropical cyclone centred within 800 km of Hong Kong poses a threat to the territory.
For your own safety, you should stay alert at all times and be prepared to deal with changing conditions at short notice. Remember that areas that may have been previously sheltered may quickly become exposed.
Neither should you relax precautions when the tropical cyclone is moving away from Hong Kong, as high winds are likely to persist for some time. You should stay indoors where it is safe until winds moderate.
Information on other hazards associated with the tropical cyclone will be included in warning bulletins. When necessary, separate warnings of heavy rain, flooding and landslips will be issued.
Precautionary Measures
Actions to take when a Standby Signal No.1 is in force:
Precautions should be taken. If you are planning an outing, remember that the tropical cyclone may affect your trips. Beware that strong winds may occur over offshore waters. Beware of possible swells. Listen to radio, watch TV or browse the Observatory's website and mobile app for latest information of the tropical cyclone.
Actions to take when a Strong Wind Signal No.3 is in force:
Make sure objects likely to be blown away are securely fastened or taken indoors. Overhanging facilities and temporary structures outdoors should be securely fastened or placed on the ground. Drains should be cleared of leaves and rubbish. People in low-lying areas should take precautions against flooding. Stay away from the shoreline and not to engage in water sports. Small vessels should seek shelter without delay. Listen to radio, watch TV or browse the Observatory's website and mobile app for further information about the tropical cyclone.
Actions to take when a Gale or Storm Signal No. 8 is in force:
Complete all precautions now before gales commence. Lock all windows and doors, insert reinforced shutters and gates if they are available. Adhesive tape fixed to large window-panes in exposed positions will reduce damage and injury by broken glass.
Do not stand near windows on the exposed side of your home. Make sure you have a safe place to shelter, should windows be broken.
Owners of neon signs should switch off the electricity supply to the signs.
Park your car where it is safe.
Owing to storm surge, low-lying areas may have serious flooding or backflow of seawater. Avoid going to likely affected low-lying areas and stay away from dangerous places.
Avoid staying in the street. Return home as soon as possible if conditions so permit.
Actions to take when an Increasing Gale or Storm Signal No. 9 is in force:
Stay indoors. If you are reasonably protected, stay where you are. Do not touch electric cables that have been blown loose.
Stay away from exposed windows and doors because glass, already under strain from wind pressure, will shatter easily if hit by a flying object. Make sure you have a safe place to shelter. You should only fix broken windows and doors when there is no danger in doing so.
People outdoors should find a safe place now and remain there until the danger is over.
Actions to take when a Hurricane Signal No. 10 is in force:
