Right now
The most recent data we hold from NASA FIRMS (VIIRS) arrived 6 minutes ago, and this point is in it.
One other detection within 20 km in the last 24 hours, <1 km from here.
Recorded by satellite today.
A thermal anomaly is a snapshot of one satellite pass, not a record of a fire’s life: we cannot say whether it kept burning after that pass.
It is the 10th strongest of the 861 detections recorded within 20 km of this point since 12 February 2024. Another comparable one was recorded here earlier the same day.
What the source measured
NASA FIRMS (VIIRS) reported 16 fire pixels with a combined fire radiative power of 174 MW, at high confidence, 2 km from South Yuba City.
The 16 pixels cover about 2.2 km² — that is the footprint of the detection grid at 375 m resolution, not an estimate of how much land burned.
FIRMS does not report burned area, and neither do we.
An estimated 77,154 people live within 20 km of this point.
MET Norway did not answer for this point when the page was rendered, so no wind is shown.
This is the lowest radiative power we have recorded at this point, over 16 readings since 6 September 2026 — the previous range was 174 MW to 175 MW.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 44 out of 100, at 74 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.
Computed under scoring rules v4. Rows carrying other versions were judged by different rules and are not directly comparable.

Safety Information
If a wildfire is approaching: follow evacuation orders immediately. Do not wait to see the fire. Close all windows and doors, remove combustible materials from around your home, and have an emergency go-bag ready. Air quality can deteriorate rapidly even at distance from the fire front — monitor local air quality advisories.
Series begins 8 March 2026 for live collection; the monthly chart also counts backfilled detections from 10 February 2024. Collection gap: 14-26 August 2026.
