Tropical Storm No.8 63-87?

Severe tropical storm 88- 1 17 9?

Hong Kong's tropical cyclone warning signals 1 to 7 were first used in Hong Kong in 19 17 to represent storm conditions. Among them, No.2 to No.5 respectively indicate that gale will blow Hong Kong from northwest, southwest, northeast or southeast. 193 1 year, changed to no. 1, No.5, No.6, No.7, No.8, No.9, 10, where No.5 to No.8 respectively represent strong winds from the above four directions. 1956, the No.3 strong wind signal was added between the warning signal 1 and the No.5 strong wind signal. In order to avoid causing public confusion, starting from 1973 1 month 1 day, typhoon signals No.5 to No.8 were changed to four types of signals: Northwest No.8, Southwest No.8, Northeast No.8 and Southeast No.8 respectively. This signal system has been used to this day. Tropical cyclone warning signals were originally intended for the convenience of navigators. However, after many years, this signal has been widely adopted by the public. At present, tropical cyclone warning signals in Hong Kong are divided into: alert signal No.1, strong wind signal No.3, northeast gale or storm signal No.8, northwest gale or storm signal No.8, southeast gale or storm signal No.8, southwest gale or storm signal No.8, gale or storm enhancement signal No.9 and hurricane signal No.10.

The Observatory has issued Hurricane SignalNo. 12 in 2005 since records were recorded in Hong Kong. 10 is 14 tropical cyclones, of which 4 are super typhoons, namely 1979' s Hobe, 1964' s Ruby and 1962' s Dai Wen. In addition, in 20 12, a strong typhoon "Vicente" hit Hong Kong, and the Observatory issued a hurricane signal of 10.

Hong Kong has been hit by typhoons many times. After the typhoon, the city was devastated, causing casualties. In the past, Hong Kong was a fishing village and a trading port, and the typhoon struck, which severely hit the livelihood of fishermen and businessmen. 1874 "Typhoon JOE" severely hit the economy of Hongkong. Coastal areas were flooded by storm surges, houses were seriously damaged, warehouses were flooded, and many ocean-going ships and fishing boats sank, killing more than 2,000 people. The typhoon made the colonial government aware of the importance of weather warning, which led to the establishment of the Observatory, in order to make early forecasts before typhoons hit Hong Kong in the future, so that citizens can take precautions as early as possible, formulate their own plans and reduce losses. After that, the Hong Kong Government will review the wind prevention mechanism after each typhoon and constantly improve urban construction to effectively resist the storm.
