Modeled smoke
Seventeen NOAA HRRR-Smoke samples spanning forecast hours 0–48, downloaded and decoded in this browser. The result remains provisional until every three-hour frame is verified.

Observed air
The latest nearby preliminary AirNow NowCast AQI, labeled with reporting area, distance, time, agency, and primary pollutant. It remains separate from the smoke-only model.
Reported fires
Nearby WFIGS wildfire and incident-complex records. Proximity does not prove smoke origin, and operational attributes can be incomplete or delayed.
Smoke Window calls modeled smoke below 4 µg/m³ “low.” Its planning window requires two consecutive three-hour samples below that site-created threshold. Conditions between samples may differ. This is not AQI, a health category, or a guarantee of clean air.

Method and spatial limits
Smoke Window shows NOAA HRRR-Smoke deterministic model guidance for primary fire-emitted fine-particle mass near the lowest model level, about 8 meters above ground, on an approximately 3 km grid. It is not a measurement, AQI, official air-quality forecast, or street-level prediction. Fire-emission estimates, plume rise, wind, terrain, mixing, precipitation, deposition, and forecast lead time all introduce uncertainty.
