Fires near Ontario right now
NASA's VIIRS sensors detected 34 thermal hotspots in 18 separate clusters within 80 km of Ontario, California, United States in the last 48 h. The closest is 9 km ESE of the city centre (8 km N of Eastvale), with 1 detection and a peak fire radiative power of 0 MW, which is low-intensity for a single 375 m pixel.
4 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.
Every nearby cluster is low intensity (peak under 10 MW), which is typical of agricultural or garden burning, industrial heat sources such as steel works or flares, or small fires rather than a spreading wildfire.
The largest nearby cluster by detections is 61 km WSW (5 km ESE of Carson) with 4 detections; first seen Sat 3 am and last seen Sun 2 am local time.
Across United States there are 576 fire clusters in the same window, 48 of them in California.

Smoke and wind
Current wind data was unavailable for this page; smoke generally drifts with the wind, so check local conditions.
Smoke shows up first as PM2.5 on air-quality monitors; the Ontario 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.
InciWeb (inciweb.wildfire.gov) lists federal wildfire incidents; in this state also check CAL FIRE (fire.ca.gov/incidents). Evacuation orders come from county sheriffs and emergency management, often via Genasys Protect (protect.genasys.com) or local alert apps.
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.
