解读中国天气预警颜色分级
When China issued its first red alert for rain this year, it marked a critical moment. The alert, the highest level, is part of a simple but effective warning system. Understanding it helps keep people safe during dangerous storms.
China's meteorological warning system was launched in 2004. It uses four colors: blue, yellow, orange, and red. Blue means mild risk, while red signals extreme danger. For rain, a red alert usually indicates that over 100 millimeters of rain may fall in a few hours. That can cause flash floods and landslides.
