LAS VEGAS — Officials have issued a dust advisory for Southern Nevada as strong winds are expected to impact air quality across the region.
The Clark County Division of Air Quality announced the advisory will be in effect Tuesday, March 31, from 10 a.m. to 11 p.m. PDT.
Forecasters expect sustained winds of 25 miles per hour, with gusts reaching 40 mph or higher. These conditions can lead to increased airborne dust across the Las Vegas Valley.
Health risks linked to airborne dust
Airborne dust is a form of pollution known as particulate matter, or PM. These small particles can enter the lungs and cause health problems.
According to the U.S. Environmental Protection Agency, dust can worsen respiratory conditions and affect overall health.
Certain groups face higher risks, including:
- People with heart or lung disease
- Older adults
- Children
Officials say these groups may feel better staying indoors during periods of poor air quality.
Physical activity outdoors can increase exposure. Residents with existing health conditions should consult a doctor if they have concerns.
Understanding air quality levels
The Environmental Protection Agency uses the Air Quality Index (AQI) to measure pollution levels.
The AQI uses color-coded categories to show when air quality may affect health.
An AQI reading of 101 or higher is considered unhealthy for sensitive groups.
During windy conditions, dust levels can rise quickly, pushing air quality into unhealthy ranges.
Safety tips to reduce dust exposure
Officials recommend several steps to limit exposure during the advisory.
First, reduce outdoor activity, especially during strong winds. Limiting exertion can lower the amount of dust inhaled.
Next, keep windows and doors closed to prevent dust from entering homes.
Residents should also run air conditioning systems in homes and vehicles. These systems help filter airborne particles.
In addition, checking and replacing indoor air filters can improve air quality inside the home.
Drivers should take precautions as well. Slowing down on unpaved roads can help reduce dust.
Officials also advise against cutting across vacant lots, which can stir up dirt and debris.
Off-road vehicles should only be used in approved areas outside the urban Las Vegas Valley.
Reporting excessive dust conditions
Residents can report large amounts of blowing dust from construction sites or vacant lots.
The county has set up a dust complaint hotline for these issues.
Phone: 702-385-DUST (3878)
Officials encourage the public to report unsafe conditions to help reduce dust pollution across the valley.
How to stay updated on air quality
Residents can monitor air quality conditions through several official resources.
Daily forecasts are available on the Clark County air quality website.
Social media updates are also provided by local agencies.
In addition, residents can sign up for alerts through EnviroFlash or use the AIRNow mobile app for real-time updates.
These tools help people stay informed and make safer decisions during poor air quality events.
