解读中国天气红色预警的含义
In late June, China's National Meteorological Center issued its first red alert of the year for torrential rain. The warning covered many provinces, including Chongqing, where heavy downpours triggered severe floods and landslides. For millions, this urgent message raised a key question: just what does a red alert mean? In China's color-coded warning system, red signals the most extreme danger, demanding immediate action.
The system has four colors: blue (low impact), yellow (moderate), orange (high risk), and red (extreme danger). For rain, a red alert means rainfall over 250 millimeters in 24 hours or over 100 in 3 hours, and continuing. Such storms can flood streets within minutes and trigger landslides. Created in 2007, this warning scale helps everyone from officials to citizens understand the threat instantly.
