Unlike the general term “downpour” in English,
暴雨 in China is part of an official, color-coded weather warning system (暴雨预警信号 - bàoyǔ yùjǐng xìnhào). These warnings—blue, yellow, orange, and red, in increasing order of severity—are issued by meteorological bureaus to alert the public to potential dangers like flooding (
洪水 - hóngshuǐ), landslides, and traffic chaos. A “red alert” for
暴雨 can lead to school and business closures.
