Clark County officials have issued an air quality alert, advising people — especially those prone to respiratory problems — to stay indoors and away from an unhealthy layer of haze hanging in the still air over the Las Vegas Valley.
Air Quality Engineering Manager Mike Sword says smoke from a wildfire and dust from a storm last night in Arizona may be to blame for the debris over Boulder City and Las Vegas.
His office hasn't yet identified the exact cause behind the haze, which was first detected about 1 a.m. Thursday.
Authorities rate Boulder City air conditions as hazardous, meaning all residents are likely to be affected by the haze.
Under the alert, children, seniors and people with chronic respiratory problems are urged to stay indoors. For people without respiratory problems, it is safe to go outside, officials said, but the air quality could trigger allergy-like symptoms in some.
For those looking to minimize the impact of the poor air quality, officials suggest limiting outdoor exertion, keeping windows closed and changing indoor air filters if they are dirty.
