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.

At monitoring sites across the county, Northern Nevada Public Health is keeping tabs on the Air Quality Index.

“Smoke can change rapidly given different weather conditions and fire conditions," said air quality specialist Ben McMullen.

Smoky conditions typically persist through the morning and evening hours, he added, as wind kicks in during the afternoon.

If the AQI reaches unhealthy levels, the county advises residents to stay inside, especially sensitive groups like seniors, children and people who are active outdoors.

“Things you can do are try to set up a clean room – so that would involve an air purifier or an area that has good access to your air conditioning," McMullen said.

Residents should avoid activities that kick up particles and smoke, like vacuuming, lighting candles, and frying food.

McMullen added that it's important to check the AQI frequently as conditions change.

“We can really only predict with a lot of certainty two days out," he said.
