People across a wide area of the United States, including New York, were under alert on Wednesday due to poor air quality from thick smoke caused by wildfires in Canada.
New York Mayor Eric Adams warned that the city was experiencing an unprecedented level of air pollution, with residents observing dark orangish smoke and an unusual smell in the air. The conditions disrupted some flight schedules and led to the postponement of sporting events.
"We're in the worst of the conditions" and the alert is expected to be in place until Thursday night, the mayor said in a Twitter post, advising people to wear masks and limit outdoor activities.
The same day, the city's air quality became the worst in the world due to the smoke, according to real-time rankings by Swedish air purifier maker IQAir AG.
We're in the worst of the conditions, but the Air Quality Health Advisory has been extended until 11:59 pm Thursday — which our teams have been anticipating.— Mayor Eric Adams (@NYCMayor) June 7, 2023
Mask up and limit your outdoor activities.
