🔥 What’s Happening?

Smoke from ongoing Canadian wildfires is drifting into northern Illinois and significantly affecting the air quality across the Chicago metro, including Aurora, Naperville, and neighboring suburbs.

Thursday morning’s Air Quality Index (AQI) readings entered the “Unhealthy” category in multiple areas, prompting action by the National Weather Service (NWS) and AirNow.gov.

🚨 Who’s At Risk?

According to public health guidelines, those especially vulnerable include:

• 🧒 Children
• 👵 Seniors
• 😷 Individuals with asthma or chronic lung conditions

The NWS strongly urges these groups to limit outdoor exposure, particularly during the hottest part of the day or when haze is visible.

📉 AQI Breakdown

Current readings range between 150–170 AQI, which falls in the “Unhealthy” range. The primary pollutant is fine particulate matter (PM2.5), which penetrates deep into lungs and can trigger:

• Coughing

• Worsened asthma symptoms

🛑 What You Should Do Now

✅ Stay Indoors with windows closed
✅ Run air conditioners or purifiers on recirculation
✅ Delay outdoor workouts or errands
✅ Avoid refueling your vehicle before 7 PM

“People with respiratory diseases such as asthma should limit prolonged outdoor exposure,” the NWS said.

🚗 Reduce Emissions While Alerts Are Active

• Combine driving errands into one trip
• Use public transportation or carpool
• Avoid idling your car for long periods
