Dust advisory returns for Las Vegas Valley, thanks to Arizona storms

Dust advisory returns for Las Vegas Valley, thanks to Arizona storms Clark County’s air quality shifted Thursday as windblown particulate from Arizona thunderstorms moved into the Las Vegas Valley. The influx of particles prompted the Clark County Environment & Sustainability’s Division of Air Quality to issue a particulate advisory on Thursday, set to expire at midnight the same day. The county continues to operate under a seasonal ozone and wildfire smoke advisory that will remain in effect through September 30. The moderate air quality reading occurred on the second‑to‑last day of an extreme heat warning issued by the National Weather Service. **Tips to limit exposure to dust** - Airborne particulate is a form of inhalable air pollution known as particulate matter (PM), which can aggravate respiratory conditions, the agency noted. Under windy conditions, individuals with heart or lung disease, older adults and children may benefit from staying indoors as much as possible. They could face greater risk from particulates, particularly when they are physically active, according to the U.S. Environmental Protection Agency. - Limit outdoor exertion on windy days when particulate is present in the air. - Keep windows and doors closed. - Run your air conditioner in your home and vehicle to filter out particulates. - Consider replacing indoor air filters if they are dirty. - Avoid taking shortcuts across vacant lots. - To keep dust down, drive slowly on unpaved roads. - Operate off‑road vehicles only in approved areas outside the municipal valley. To report excessive blowing dust from construction sites, vacant lots or facilities, call the Environment and Sustainability dust complaint hotline at 702‑385‑DUST (3878).
