The air over the Salt Lake Valley was difficult to see through Friday, and nearly as hard to breathe — and that’s not likely to change over the weekend.
Thick fog descended over much of the valley Friday, limiting visibility for travelers. With the fog came unhealthy levels of particulates, known as PM 2.5, in Salt Lake County, according to the Utah Division of Air Quality.
Solid-fuel burning devices, such as wood stoves, cannot be used when air quality is in the red zone. No open burning is allowed, including fire pits, fire rings and campfires.
