Smoky and hazy conditions in Indianapolis, caused by wildfires in Canada, are expected to linger into Tuesday evening, according to the National Weather Service.

"People looking outside will notice a hazy feel,” said NWS meteorologist Andrew White. “Visibilities are not quite as high as they normally are due to some of that smoke. We are still kind of dealing with the lingering impacts from those fires.”

Smoke from the wildfires in Quebec and Nova Scotia is expected to linger higher in the atmosphere for a few more days in the Indianapolis area after Tuesday evening. Once higher in the atmosphere, the smoke will cause less of an impact on the ground, White said.

Hazy conditions can cause irritation for people with asthma or other respiratory issues, White said.

The Canadian wildfires caused hazy skies from the Ohio Valley to North Carolina and South Carolina. Parts of the Upper Peninsula of Michigan, Southeastern Minnesota, and all of Wisconsin have had air quality advisories in effect this week.

In Central Indiana air quality is considered unhealthy for many and is worse today than at the same time yesterday.

Sensitive groups such as older adults, children or those with pre-existing respiratory conditions are particularly vulnerable to air quality issues. Air pollution can cause inflammation, weakens someone’s immune system and can increase the risk of asthma, lung cancer or other chronic lung diseases.

A Knozone Action Day was declared for Indianapolis by the city’s Office of Sustainability on June 3. Knozone Action Days are declared when ozone or fine particulate matter levels rise above certain thresholds in the city.

What is the status of the Canadian wildfires?

More than 6.7 million Canadian acres have already burned in 2023, federal officials announced last week, marking one of the worst starts to wildfire season. Around 14,000 people were forced to evacuate Quebec with over 150 fires, CBC News reported. Officials said firefighters contained a wildfire in Nova Scotia on Sunday but that another one was still burning out of control covering nearly 100 square miles, according to the Associated Press.
