"Smoke from wildfires burning in south-central Canada and parts of Minnesota is
spreading across the US, prompting air quality alerts in more than 20 states
with millions of Americans expected to face unhealthy air conditions this week.
The smoke from the more than 180 active wildfires in northern Ontario briefly
made Toronto’s air quality among the worst in the world on Wednesday. By
Wednesday night, the smoke had spread across several US states, from Minnesota,
where multiple wildfires are also burning, to New York, blanketing the skies in
haze and worsening air quality.
The National Aeronautics and Space Administration (Nasa) said that winds
carried smoke from the Ontario fires “primarily south-east over much of the
southern part of the province, as well as parts of Quebec and the US midwest
and north-east, tinting the sky shades of gray and yellow and the sun orange in
many areas”.
As of Thursday, air quality alerts have been issued for parts of North
Carolina, Minnesota, Vermont, Connecticut, New York, Massachusetts, Rhode
Island, New Jersey, New Hampshire, Pennsylvania, Illinois, Indiana, Ohio,
Delaware, West Virginia, Colorado, Virginia, Maryland, Washington DC, Michigan
and Wisconsin.
According to a map of air quality conditions provided by the US Environmental
Protection Agency, air quality was at “unhealthy” levels on Thursday morning in
parts of Pennsylvania, Delaware, New Jersey, New York, Ohio and Michigan with
officials urging residents to “take precautions by reducing outdoor, activity”.
On Thursday afternoon, the air quality wasrated as “very unhealthy” in parts of
Pennsylvania, New York, Ohio, Michigan, Illinois, Wisconsin, Minnesota and
Indiana, while in certain parts of Pennsylvania, Michigan, including near
Detroit, as well as areas of Ohio, Illinois, Wisconsin and Minnesota, the air
quality was listed as “hazardous”, with officials urging residents there to
“stay indoors”.
On Thursday afternoon, Minneapolis was listed as the city that now has the most
polluted air in the world on IQAir’s global rankings, followed by Detroit and
Chicago."
