Typhoon classification in Hong Kong
Typhoon in Hong Kong can be divided into No.1, No.3, No.8, No.9 and No.1 (from small to large in power) according to the degree of wind impact on Hong Kong.
typhoon warning signals in hong kong are divided into five grades, namely, alert signal No.1, strong wind signal No.3, gale or storm signal No.8, gale or storm signal No.9 and hurricane signal No.1. Since 1946, there have been 16 tropical cyclones with typhoon intensity or above, which caused the Hong Kong Observatory to issue the No.1 hurricane signal.
Typhoon warning signal is an early warning signal used by relevant departments to issue typhoon disaster warning according to relevant laws and regulations. Typhoon warning signals are divided into four levels, which are represented by blue, yellow, orange and red respectively. On August 16th, 24, China Meteorological Bureau issued "Trial Measures for Issuing Early Warning Signals of Sudden Meteorological Disasters", which classified typhoon early warning signals into four levels: blue, yellow, orange and red, but some provinces and cities classified them according to their own characteristics.
measures to deal with typhoons
1. Pay close attention to the weather forecast: pay close attention to the typhoon warning information released by the meteorological department to understand the path, intensity and possible impact of typhoons. This can help you prepare in advance and take necessary preventive measures.
2. Avoid dangerous areas: If a typhoon strikes, try to avoid staying in vulnerable areas, such as rivers, beaches and low-lying areas. Move to a safe place as soon as possible, such as a tall building, a solid building or a shelter.
3. Do a good job in family wind protection: close doors and windows, and fix objects that are easily blown to prevent them from becoming a source of injury. Clean things around balconies and houses to prevent falling objects from injuring people.
4. Travel safety: Try to avoid going out when the typhoon comes. If you have to travel, you should try to avoid wading, because the current in the flood water can be dangerous. Choose safe means of transportation, such as cars instead of bicycles or motorcycles.
5. Make emergency preparations: prepare necessary emergency items, such as flashlights, batteries, portable chargers, first aid kits and other necessary emergency supplies. Make sure that family members know how to contact your relatives in other places.
