According to the warning signals of different colors, people should take different defensive measures. Residents in the blue rainstorm warning area had better stay indoors. When it is too late to enter the room, stay away from wires, avoid getting wet under big trees, hold metal objects or answer mobile phones, and stay away from billboards and simple buildings.
When the warning is yellow, people had better not ride bicycles or drive, and try to avoid driving in stagnant water. The traffic department should take traffic control measures in heavy rainfall sections. After the concave overpass and culvert accumulate water, the overpass should be blocked immediately and warning signs should be set up, and necessary drainage measures should be taken.
Special attention should be paid after the orange or red rainstorm warning is issued. All relevant departments should immediately enter the emergency post, closely monitor and take rescue measures; People near mountains, hills and rivers should immediately evacuate to safe areas; When the vehicle is turned off or cannot run normally, the driver should observe the surface runoff. If runoff is rapidly gathering, they should resolutely give up vehicles to avoid it.
