The Hong Kong hit two No. 8 typhoon signals in a row, and Lion Rock came to the rescue with a compass relay.
Two times the No. 8 typhoon signal, the observatory's decision to make waves and fall waves, the release time and the language also caused controversy.

The Assistant Director of the Observatory, Chen Baiwei, explained on the radio program this evening (13th) that "sunrise" is also a specific time. The authorities will make forecasts according to the situation and changes in the weather. If the forecast has a high degree of confidence and confidence, it will be used. More accurate time.
He also explained that the lion rock's moving path is relatively erratic, posing a greater challenge to the forecasting work, but he promised to review the forecasting technology and information transmission work.

The Observatory announced last night that "Signal No. 8 will be maintained at least before sunrise this morning." The public questioned why the exact time could not be provided.
Chen Baiwei described that "sunrise" is already a specific time. It is also said that the Observatory will forecast the weather based on conditions and changes in the weather. If the forecasting accuracy is higher and the confidence is greater, the more accurate time will be used.
Compass path is relatively stable
The warning about tropical cyclone Lion Rock has been criticized. Chen Baiwei also said that the moving path of Lion Rock is relatively erratic. Although it is far away from Hong Kong, strong winds are blowing, which poses a greater challenge to the forecasting work. However, the following compasses move the path. It is more stable, so that the Observatory can already see through its movement and intensity changes and give timely warnings.
