解读暴雨红色预警：何时触发最高警报？
China recently issued its first red alert for rainstorms this year. Torrential rains have flooded many areas across the country. But what exactly triggers this highest warning? The red alert is part of a four-tier system that helps protect people from extreme weather.
China's meteorological warning system uses four colors: blue, yellow, orange, and red. Blue signals the lowest risk, while red means the most severe danger. Each color is linked to specific weather events like typhoons, heatwaves, or rainstorms. For rainstorms, the thresholds become stricter as the color rises. The system helps the public and government prepare for bad weather.
