Think the air in the Las Vegas Valley was ugly Tuesday night? You might not have seen anything yet.
A day after smoke from the fire at Mount Charleston drifted in the valley, the Clark County Department of Air Quality issued an advisory Wednesday because of smoke from both the mountain and from wildfires in Southern California.
The advisory will be in effect through Wednesday evening.
Officials said that although the air might look bad, unhealthy levels of air pollution are not expected. But, officials said, it may be best for children, elderly individuals and people with respiratory diseases to stay indoors. Other precautions include limiting outdoor exertion and keeping windows closed.
