Air Quality Wildfire Smoke Advisory Issued for Saturday

Fires burning in Yosemite National Park may send smoke into Southern Nevada.

As smoke from the wildfire in Mexico dissipates, Clark County’s Division of Air Quality (DAQ) is issuing a smoke advisory for Saturday, Sept. 19, due to smoke from wildfires burning to the north. Smoke from multiple fires near Yosemite National Park and Reno is expected to drift into Southern Nevada. Residents should take necessary precautions, especially children, older adults and people with respiratory conditions.

Smoke is made of small particulates and other pollutants that can aggravate respiratory diseases and contribute to ground-level ozone formation. Exposure to smoke can induce coughing, wheezing and shortness of breath even in healthy people.

According to the EPA, people who may be most sensitive to elevated levels of particulates and ozone include individuals with respiratory problems, cardiac disease, young children and senior citizens. Consult your physician if you have a medical condition that makes you sensitive to air quality conditions.
