NO “Red Alert” for Beijing despite 6th consecutive days of hazardous smog

Satellite remote monitoring showed 980,000km², or 10 percent of the country,  blanketed by smog Sunday including Beijing and the provinces of Liaoning, Hebei, and Shanxi.

Beijing entered its six consecutive day of hazardous smog (AQI above 300), described by as “Apocalyptic smog” by the residents, on Tuesday. However, the authorities have failed to issue a “Red Alert” for the capital, breaking their own rules.

“A red alert indicates the most serious air pollution (AQI above 300) for three consecutive days. An orange alert indicates heavy to serious air pollution (AQI between 200 and 300) alternately for three consecutive days. A yellow alert indicates severe pollution for one day or heavy pollution for three consecutive days,” said a report.

Beijing was placed on “Yellow Alert” on Thursday, but the alert was upgraded to “Orange” for the first time on Friday, where it has stayed since.

The poisonous smog is forecast to linger until at least Thursday, according to the China Meteorological Administration.
