红色预警：中国四级灾害预警体系解读
As torrential rains swept across multiple regions, China's meteorological authority issued the year's first red alert, the highest level in its four-tier weather warning system. This alert signals extreme danger and triggers a coordinated emergency response.
China uses a color-coded system to warn the public about severe weather. The four tiers are blue, yellow, orange, and red, representing increasing levels of risk. A blue alert means moderate weather that may cause some inconvenience. Yellow indicates heavier impact, while orange warns of major disruptions. Red, the top level, is reserved for the most dangerous conditions.
