The tropical storm "Lion Rock" struck Hong Kong. After the No. 8 typhoon signal was hoisted yesterday (9th), the Observatory originally said that it was expected to change the No. 3 typhoon signal in the early afternoon. It was postponed and the No. 3 typhoon signal was officially changed to 4:40 am today (10th).
Regarding the six-degree change, Lim Ching-chih, senior scientific officer of the Observatory, explained that the storm conditions are special this time. The "Lion Rock" circulation is wide, and it has a common effect with the northeast monsoon, making Hong Kong in a "composite zone", and the development of rain zones also affects the wind conditions. The certain impact of the "Lion Rock" broke a record and became a storm that was more than 500 kilometers away from Hong Kong but hoisted the No. 8 typhoon signal.
She also said that the Observatory uses data as its scientific basis. When 4 of the 8 reference wind stations reach the level of gale or storm, it will issue the No. 8 gale or storm signal.

Among them, Ngong Ping recorded a wind speed of 126 kilometers per hour, reaching the level of "hurricane", Cheung Chau also reached the level of "storm", and other areas also Affected by strong winds.
She said that when 4 out of the 8 reference wind stations reached the level of gale or storm, they would issue the No. 8 gale or storm signal, emphasizing the use of data as the scientific basis and the safety of citizens as the primary consideration. She said frankly that this time the signal was issued. The decision was made right.
However, regarding the confusion caused by information, Lin Jingzhi said that the Observatory will collect opinions from the public and review the actual situation, then review the forecasting technology, and improve the arrangements for message transmission.

Some citizens questioned the weather on Friday and the rain was heavier, but the wave 8 was hoisted on Saturday. She said that the tropical cyclone warning signal mainly depends on the wind and is based on forecasts, which is different from the rainstorm warning signal.
She said that she understands the feelings of the public, but the observatory needs to make decisions based on science, and the feelings of the public are associated with many factors, or are affected by heavy rain, which makes some people feel that the wind is stronger on Friday than on Saturday.
In addition, the tropical storm "Compasses" is gradually strengthening, and it is expected that it will affect Hong Kong later on Tuesday.
Lin Jingzhi reminded the public not to take it lightly, as the weather may deteriorate rapidly due to the same mutual effects, and the public must be prepared.
