When Hurricane Signal No. 10 signal is issued, it means that winds of hurricane force (i.e.118 km/h or more) are expected to affect the territory. Since hurricane force winds are largely confined to a relatively narrow strip around the eye wall of a typhoon, it would normally require a storm of typhoon status to pass fairly close to (say, within 100 km of) Hong Kong. This is commonly referred to as a “direct hit”.
1. Do not go outside. If you are reasonably protected, stay where you are and keep well away from all windows. Close all interior doors and make sure children are confined to the least exposed part of your home. On no account should you touch electric cables that have been blown loose.
2. Since seas are very high to phenomenal and the current is strong with changing direction, you are advised to stay away from the shoreline and not to engage in water sports.
3. Flights at Hong Kong international airport may be affected by the weather. Please contact your airline for the latest flight information before departing for the airport.
