Smoke from California wildfires covers Southern Nevada skies

LAS VEGAS (KSNV) — The Las Vegas valley woke up to a smokey sky Monday morning because of California wildfires, according to local air quality officials.

The Clark County Department of Environment and Sustainability issued a smoke and ozone advisory because of the air quality.

Kevin MacDonald, a spokesman for the department, said in a press release the smoke can aggravate respiratory diseases and contribute to the formation of ground-level ozone.

That ozone can cause coughing, wheezing and shortness of breath, even in healthy people, according to MacDonald.

People are asked to limit their time outdoors because of the elevated ozone levels and keep windows and doors closed.
