Rainstorm warning color grade

The colors of rainstorm warning grades are as follows:

1. The blue rainstorm warning signal indicates that there will be rain (more than 5ml) in the relevant areas in the next half day. If the continuous rainfall in individual areas exceeds 5 mm, the area will continue to be affected by heavy rainfall within 12 hours. After receiving the warning signal, the government will immediately put the rainstorm prevention measures on the agenda and make emergency arrangements. Many institutions, including schools, will also arrange anti-rainstorm measures to ensure the safety of residents.

2. yellow rainstorm warning signal indicated that there will be rainfall (more than 5ml) in the relevant areas in the next 6 hours. Most areas in the south, especially those seriously affected by typhoons, will continue to be affected by heavy rains during the typhoon season. Therefore, the traffic management department will immediately carry out traffic control after receiving the yellow rainstorm warning signal to avoid traffic jams or traffic accidents. Outdoor power exposed to heavy rain will be cut off and outdoor work will be forcibly terminated.

3. The orange rainstorm warning signal indicates that there will be rain (more than 5ml) in the relevant areas within three hours, and the areas that have been continuously affected by the rainstorm will be hit by the rainstorm in the next few hours. Once the orange rainstorm warning signal is received, the individual areas most affected by the rainstorm will take measures to suspend classes and stop work, and the mountainous areas should also take flood control measures.

4. The red color of rainstorm indicates that there will be heavy rainfall (greater than 1ml) in the relevant areas in the next three hours. This signal is one of the worst rainstorm warning signals. Rainfall above 1mm is terrible, and the most terrible thing is that the relevant areas will continue to be affected. After receiving this signal, the relevant area will be completely closed and closed. Even indoors, the safety of some residents will be affected, so all outdoor activities will stop.
