Fires near Waterdown right now
NASA's VIIRS sensors detected 64 thermal hotspots in 8 separate clusters within 80 km of Waterdown, Ontario, Canada in the last 48 h. The closest is 9 km SE of the city centre (4 km ENE of Hamilton), with 36 detections and a peak fire radiative power of 5 MW, which is low-intensity for a single 375 m pixel.
2 clusters are within 25 km, close enough that smoke, ash or road closures may affect the city. Distances are measured from the city centre to the nearest detection, not to the fire's edge.
Across Canada there are 109 fire clusters in the same window, 24 of them in Ontario.

Smoke and wind
Wind at Waterdown is from the SSE at 8 km/h (gusts 15 km/h), so smoke near the city drifts toward the NNW. Relative humidity is 50% and the temperature 18°C.
Waterdown is roughly downwind of the nearest fire, so smoke and haze are likely; check the air quality page before spending time outdoors.
Smoke shows up first as PM2.5 on air-quality monitors; the Waterdown air quality page has the live reading.
Evacuations and official information
GodsView shows satellite detections only. It does not know fire perimeters, containment or evacuation zones. Always follow evacuation orders from local authorities.
CIFFC (ciffc.net) publishes the national wildfire situation; provincial fire status and evacuation alerts come from Ontario Forest Fires (ontario.ca/page/forest-fires). Alertable and local emergency alerts carry evacuation orders.
About satellite fire detections
Satellite thermal hotspots are not all wildfires: gas flares, steel works, volcanoes and planned agricultural or prescribed burns show up too. VIIRS passes over most places about twice a day, so a fire can start or grow between passes, and thick smoke or cloud can hide one.
Fire radiative power (FRP) is the heat a fire gives off, in megawatts per pixel: under 10 MW is usually a small or smouldering fire, over 100 MW an intense flaming front.
