According to IQAir, which powers the air quality rankings, Salt Lake City's is "Moderate."

The hazy skies could also have an impact on your health. IQAir says that of the 62 million people who died in 2021, air pollution was the main risk factor for more than 8 million of those deaths. Outdoor particulate matter pollution was ranked as the 5th risk factor, with 4.7 million deaths.

Damon Yauney explains the current inversion condition and when relief may come:

Valley inversions in place; Air quality getting worse- Tuesday, January 13

While a hot air mass to the West is maintaining the inversion, there could be some relief on the way. Later in the week, another system from the North will hopefully brush by Utah and bring with it wind to possibly break the inversion.

However, forecasters say it is unlikely that it will happen, and high pressure will build again next week.
