红色预警意味着什么？解读中国天气四色预警机制
When China's meteorological authority issues a red alert, it signals the most serious weather threat. The first red alert of this year came as heavy rains flooded several provinces. This highest-level warning is part of a four-tier color-coded system designed to protect public safety.
The system uses four colors: blue, yellow, orange, and red. Blue represents the lowest level, meaning people should be aware of possible weather events. Yellow calls for caution and preparation, while orange warns of more dangerous conditions. Red is the most severe and indicates extreme weather that could endanger lives. Each color corresponds to specific thresholds set by the China Meteorological Administration (CMA).
