where is the smoke in las vegas coming from

The smoke currently affecting Las Vegas is coming primarily from wildfires in California, particularly the Gifford Fire near Santa Maria on the central coast. This fire has burned over 65,000 acres and the smoke is being pushed toward Southern Nevada by southwesterly winds. The wildfire smoke has caused unhealthy air quality conditions in the Las Vegas Valley, with reduced visibility even over the iconic Strip. Additional smoke sources include smaller wildfires in Nevada such as the Gothic Fire in Nye County and fires burning in nearby Arizona and the Grand Canyon area, which contribute to the haze in the region. The wildfire smoke is primarily made up of fine particulate matter (PM2.5), which poses health risks especially for people with respiratory conditions. Residents are advised to stay indoors, keep windows closed, and limit outdoor exposure due to the poor air quality caused by this wildfire smoke originating mostly from California and some regional fires.
