Southern Nevada is no longer under an air quality advisory.
The Clark County Department of Air Quality said Wednesday that it was cancelling the warning after issuing it the day before.
Concerns about elevated levels of ozone and smoke began last week due to smoke from wildfires in California and in mountains west of Las Vegas.
But officials now say the smoke isn't significantly impacting the air and that Las Vegas' latest monsoon weather pattern is helping to curb ozone levels.
The advisories and alerts had previously urged people to stay indoors, limit outdoor exercise and run the air conditioner, as smoke and dust can aggravate respiratory illnesses.
