Right now
The most recent data we hold from NASA FIRMS (VIIRS) arrived 17 minutes ago, and this point is in it.
Nothing else has been detected within 20 km in the last 24 hours.
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 11th strongest of the 869 detections recorded within 20 km of this point since 12 February 2024. The last comparable one was on 31 August 2026.
What the source measured
NASA FIRMS (VIIRS) reported 13 fire pixels with a combined fire radiative power of 153 MW, at nominal confidence, 1 km from South Yuba City.
The 13 pixels cover about 1.8 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 78,438 people live within 20 km of this point.
Wind from SSW at 10 km/h at 23:00 UTC, according to MET Norway.

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.

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.
