What does the color of the weather signal represent?

The colors of weather forecast warning signals are blue, yellow, orange and red in turn, and they are marked in Chinese and English, which respectively represent ordinary, heavy, serious and super-serious. This practice began in China in recent two years after Europe and America. Generally speaking, above the orange signal, people should not go out and be prepared for disaster prevention.

3. The warning signals issued are tentatively classified into seven categories, such as typhoon, rainstorm, high temperature, cold wave, low temperature and cold, thunderstorm and strong wind, which are generally divided into four levels (IV, III, II and I). According to the severity and urgency of the disaster, the colors are basket, yellow, orange and red in turn, and they are marked in Chinese and English, representing ordinary, heavy, serious and super-serious respectively. The early warning signals issued by meteorological stations at all levels in the province must adopt a unified graphic library. When multiple meteorological disasters occur or forecast at the same time, multiple early warning signals should be issued at the same time according to the corresponding standards.
