Located in a sub-tropical climate zone, Hong Kong is characterized by hot, humid weather and typhoon events between May and November. Hongkongers or expatriates living here for years do not consider such weather phenomena as harmful, however, there are certain warnings you should keep in mind when hear news of an approaching typhoon, especially when living in coastal areas of Hong Kong. When a typhoon is approaching, warnings are broadcast on television and radio. Many property management offices in residential buildings or offices would also raise alerts to residents. There are various degrees of warning signals issued by the Hong Kong Observatory (HKO), the local weather authority, including real time updates of weather conditions and typhoon tracking. The severity of typhoons is categorized by HKO as follows: • Signal No. 1 – a tropical cyclone is centered within about 800 km of Hong Kong. Keep it in mind when planning activities and beware that strong winds may occur over offshore waters. • Signal No. 3 – strong wind is expected or blowing generally in Hong Kong near sea level, with a sustained speed of 41-60 km/h. Rainfall may occur. You are advised to secure all loose objects on balconies or roof tops (i.e. flower pots, garden furniture, etc.), make sure all windows and doors are properly locked. Avoid walking or working in areas exposed to gales and squalls. • Signal No. 8 – when is in force, complete all precautions before gales commence. HKO would inform about the expected time of hosting Signal No. 8, so that public have enough time to go back home from work or return to safe place. Most businesses, schools and shops closed down and flights may be cancelled. • Signal No. 9 or No. 10 – Hurricane force wind is expected or blowing with sustained speed. Stay indoors and away from exposed window and doors to avoid flying debris. There are separate warnings for heavy rain fall. For more information, please visit HKO website.
