Clark County’s Division of Air Quality has issued a smoke advisory for the upcoming Independence Day weekend, warning residents that celebratory fireworks may create elevated smoke levels throughout the valley. 

The advisory, effective Friday through Sunday, is intended as a precautionary measure rather than a deterrent to holiday celebrations, officials said 

“Who doesn’t love a good fireworks show?” said Paul Fransioli, a forecaster with the department. “But folks with breathing issues may want to take precaution if they’re near where fireworks are being discharged, increasing particulate matter pollution in the air.” 

Fireworks produce smoke containing small dust particles and pollutants that can worsen respiratory conditions including bronchitis and asthma, officials said. The particles also contribute to ground-level ozone formation, further compromising air quality. 

Health officials particularly recommend that children, older adults and individuals with respiratory or heart conditions consider staying indoors during periods of moderate or poor air quality. 

To minimize exposure to smoke, residents should stay inside when smoke is visible or detectable by smell, keep windows and doors closed and limit outdoor exercise when particle levels are high. Those with dirty indoor air filters should consider replacing them. 

The Department of Environment and Sustainability continuously monitors air pollution through monitoring stations across the Las Vegas Valley. Real-time data and forecasts are available at DESAQMonitoring.ClarkCountyNV.gov. 

Residents can stay informed about air quality conditions through the department’s website, social media accounts (@ClarkCountyDES), daily text and email alerts via enviroflash.org, and the AIRNow mobile app. 

While the advisory aims to protect public health, officials emphasize it shouldn’t discourage Fourth of July festivities — but rather encourage awareness among those most vulnerable to air quality changes.
