Ground-level ozone may reach levels considered unhealthy for sensitive groups in the Reno-Sparks area through the weekend.

Smoke from the Bear Fire is expected to have the greatest impact Thursday evening through Friday morning. 

Northern Nevada is getting hazy, as wildfire smoke travels over the Sierra from California. Reno's air quality shifted from good to moderate Monday morning, but rural communities across the region have it much worse.

To better provide air quality information to the community, Northern Nevada Public Health has recently received 16 additional air sensors to help fill in the gaps where data has historically been missing.
