SALT LAKE CITY -- Wildfire smoke from around the western U.S. has been blowing into parts of Utah, causing a decline in air quality in many parts of the state.
"Unfortunately, the West is on fire and we're being surrounded by smoke. It's blowing in all areas, in all directions and it's really having an impact on air quality," said Donna Spangler, Utah Department of Environmental Quality.
The air quality in Box Elder, Cache, Duchesne, Salt Lake, Davis, Tooele, Uintah, Utah and Weber Counties is listed as "Unhealthy for Sensitive Groups" through Friday. Utah's Division of Air Quality advises children, older adults, people who are active outdoors and people with lung diseases such as asthma should reduce prolonged or heavy outdoor exertion.
Drivers are encouraged to use mass transit, carpool and use other alternative means of transportation to reduce emissions.
