SHANGHAI/BEIJING—China’s top steelmaking province of Hebei has issued an “orange” smog alert effective from Nov. 1, with pollution expected to be “severe,” the local environment bureau said on Oct. 30.
Unfavorable weather conditions, including rising humidity and weak southerly winds, would make it harder for smog particles to be diffused, it said. Orange is the second-highest level on a three-tiered smog alert system that triggers emergency measures.
