Smoke is expected to arrive around Sep 22, 4:00AM and clear by about Sep 22, 11:00AM.
Unusually sensitive people should consider reducing prolonged outdoor exertion.
Background bands (US EPA AQI, 24-h basis): ■ Good · ■ Moderate · ■ Unhealthy for Sensitive Groups · ■ Unhealthy
| Model | Peak PM2.5 | Peak around |
|---|---|---|
| FireSmoke (UBC BlueSky) | 69 µg/m³ | Sep 22, 6:00AM |
| FireWork (ECCC) | 7 µg/m³ | Sep 22, 12:00PM |
| HRRR-Smoke (NOAA, 3 km) | 1 µg/m³ | Sep 22, 7:00AM |
Model values are for the nearest forecast grid cell to Banff; FireSmoke, FireWork and HRRR are independent and often disagree — treat the highest available value as the cautious planning number.
Observations and NowCast are total PM2.5 — wildfire smoke plus every other source — as regulatory monitors measure it, and FireWork models that same total. FireSmoke and HRRR-Smoke estimate the wildfire contribution only, so they read lower than the monitors whenever other sources matter. The optional map plume surfaces are likewise fires-only.
Little smoke at the surface or overhead.
● At the ground · ● Overhead (if mixed down)
Overhead smoke dims the sun but is not what you breathe. The dashed line shows the surface level if the whole column mixed through the boundary layer — a worst case, not a forecast · Data: NOAA HRRR-Smoke; cloud cover is from the model, not observed
Within 150 km, agencies report 1 Being held · 10 Under control.
No out of control fires are reported within 150 km.
Proximity and wind direction do not prove that a fire caused smoke at this location. Sources: BC Wildfire Service in British Columbia; Natural Resources Canada CWFIS elsewhere.
