Alerts in force
An Air Quality Alert is issued by the National Weather Service on behalf of a state or local agency when pollution is expected to reach a level that harms health. An Air Stagnation Advisory means the air will not move enough to clear what is already in it.
None are in force in Nevada right now. All Nevada warnings.

The forecaster’s discussion
Written by Clark County Department of Environment and Sustainability for Las Vegas and filed with AirNow.
Expect smoke to continue to move into the area from fires from Mexico on Friday and from Northern California on Saturday which will help push the ozone level into the Moderate AQI range. Increasing cloud coverage on Tuesday will keep ozone levels in check for a Good AQI.
Smoke
NOAA’s Hazard Mapping System smoke analysis could not be read just now.
What this means
The index runs from 0 to 500. Good is 0 to 50, Moderate to 100, Unhealthy for Sensitive Groups to 150, Unhealthy to 200, Very Unhealthy to 300, and Hazardous above that. The figure reported for a place is the highest index among the pollutants measured there, and the pollutant that produced it is named beside it.
What these numbers are. An index beside a monitor’s name is a measurement, published hourly by AirNow and preliminary until the operating agency certifies it. A category for today or tomorrow is a state or local agency forecaster’s own forecast for a reporting area. An hourly index is NOAA’s air quality model on a five-kilometer grid, not a reading from any instrument. Where a town has no monitor within reach, only the model figures appear, and the page says so.
