Hong Kong set a rainfall record for August after violent storms lashed the city on Tuesday, leading to flight delays and commuter chaos.

About 356 millimeters (14 inches) of precipitation was recorded at the Hong Kong Observatory’s headquarters through to 2 p.m., a daily high for the month, according to the weather agency. The bureau canceled rain warnings Tuesday evening after downgrading from its highest alert, but said dangerous showers and flooding were still possible.
