Weather forecast, what does the blue warning mean?

China Meteorological Bureau announced the trial measures for the release of early warning signals for sudden meteorological disasters. The "Measures" stipulate that whenever sudden disastrous weather such as typhoon, rainstorm and high temperature comes, the public can see new warning signals from TV, radio, internet, mobile phone short messages and electronic display boards located in prominent positions in cities. At present, the sudden meteorological disasters that issue early warning signals include: typhoon, rainstorm, high temperature, cold wave, fog, sandstorm, thunderstorm and gale, hail, blizzard and road icing, *** 1 1. Early warning signals are generally divided into four levels. According to the severity and urgency of the disaster, the colors are divided into blue, yellow, orange and red, which represent ordinary, heavy, serious and particularly serious respectively.

Grade 1 is very unlikely; Level 2 is less likely; Level 3 is more likely; Level 4 is very likely; Level 5 is very likely; 2. The rainfall data table causing geological disasters is Grade 3, which is the level of concern in the forecast (rainstorm: 38.0-74.9mm); Level 4, which is an early warning level in the forecast (rainstorm: 50.0-99.9mm, easy to cause geological disasters); Level 5, the warning level in the forecast (rainstorm: 100-250 mm); 1-2 level, notify the land and resources department; Level 3-5, short-term forecast and imminent disaster forecast are put forward by the county land and resources bureau and the county meteorological bureau, and reported to the county * * * and announced to the public, and notified in place step by step according to the hidden danger points and monitoring of the county, township, village and responsible person. 3. Classification standard of rainfall: (calculated on a 24-hour basis) 1, and rainstorm: 25.0-49.9mm2. 250mm Description: Warning signals of disastrous weather are divided into eleven categories: typhoon, rainstorm, high temperature, cold wave, fog, thunderstorm and gale, sandstorm, hail, blizzard and road icing. Early warning signals are generally divided into four levels. According to the severity and urgency of disasters, the colors are blue, yellow, orange and red in turn.

According to the characteristics and early warning ability of different disasters, the early warning grades and standards of different disasters are determined. When a variety of meteorological disasters occur or are expected to occur at the same time, a variety of early warning signals can be issued simultaneously according to the corresponding standards.

Specifically, it can be Baidu's "gale warning level".
