Extended data
Typhoon warning is divided into four warning levels: blue, yellow, orange and red. Among them, red warning signal is the most terrible. Generally, after the release of this level, it shows that the typhoon has landed strongly in the local area, which will bring some damage. In addition, there is a white warning signal, which is only set up in Guangdong Province.
After the general typhoon warning is issued, the relevant areas will stop large-scale indoor and outdoor gatherings, suspend classes and suspend business (except for special industries). Before the typhoon comes, people should try to stay in windproof and safe places. Water operations and passing ships in relevant waters should return to Hong Kong to take shelter from the wind, strengthen port facilities, and prevent ships from anchoring, grounding and collision.
Every time a typhoon lands, it is almost accompanied by heavy rain, and the precipitation can reach four or five hundred milliliters. Before the typhoon comes, we should reserve daily food, articles and drinking water.
Legal basis: On August 16, 2004, China Meteorological Bureau issued the Trial Measures for Issuing Early Warning Signals of Sudden Meteorological Disasters, in which typhoon early warning signals are divided into four grades: blue, yellow, orange and red.
