Seattle Air Quality Advisory Issued as AQI Exceeds 150

Seattle residents woke up this week to AQI readings spiking above 150, prompting health officials to issue an air quality advisory for the greater Puget Sound region.

The elevated particulate matter levels stem from a combination of industrial emissions and weather patterns trapping pollutants close to ground level. Officials recommend limiting outdoor activities, especially for sensitive groups.

What You Should Do

Keep windows closed during peak pollution hours (typically 6-10 AM and 4-8 PM). Run HEPA air purifiers if you have them. Check AirNow.gov for real-time readings before outdoor exercise.

The advisory is expected to lift by Thursday as a cold front moves through the region.
