Do you know the blue, yellow, orange and red rainstorm warnings? How to identify this signal?

There are four levels of rainstorm warning signals, which are expressed in four colors: dark blue, light yellow, orange and bright red. Blue warning:/kloc-within 0/2 hours, the precipitation will reach more than 50 mm, or it has reached more than 50 mm and the precipitation may continue. Yellow warning: within 6 hours, the precipitation will reach more than 50 mm, or it has reached more than 50 mm and the precipitation may continue. Orange warning: within 3 hours, the precipitation will reach more than 50 mm, or it has reached more than 50 mm and the precipitation may continue.

Red warning: within 3 hours, the precipitation will reach 100 mm or above 100 mm and the precipitation may continue. How should we deal with different rainstorm warnings? Experts pointed out that in areas covered by the blue rainstorm warning, it is best to stay indoors and avoid opening windows. After the yellow rainstorm warning is issued, people should try not to ride bicycles or drive when it rains. When the rainstorm orange warning or red warning occurs, people should look for safe engineering buildings to escape.

A relatively comprehensive method for issuing and disseminating meteorological disaster early warning data signals consists of names, signs, specifications and defense manuals, which are divided into strong typhoon, rainstorm, blizzard game, cold current, gale, sandstorm, continuous high temperature, drought, lightning, hail, first frost, dense fog, haze, road icing and so on. Alerts of different colors indicate different levels. Generally speaking, there are four colors: blue, yellow, orange and red, which match the degree of harm, urgency and development trend that climate disasters may cause.

It is divided into four levels (general), three levels (heavier), two levels (serious) and one level (particularly serious). When we see at least one warning, we need to pay attention to the traffic arrangements. For example, when at least one level of blue rainstorm warning data signal is issued, everyone should carefully consider the plan of going far away, traveling or going to low-lying areas, and care about the weather changes anytime and anywhere. With the improvement of meteorological disaster early warning data signal level, everyone should make corresponding protection preparations in advance, and don't "turn a deaf ear" or "turn a deaf ear".
