Wildfires near Norfolk County

CanadaNASA FIRMS (VIIRS)

Right now

The most recent data we hold from NASA FIRMS (VIIRS) arrived 13 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.

No stronger detection stands among the 3312 recorded within 20 km of this point since 10 February 2024 — 3 others scored the same. The last comparable one was on 22 September 2026. 16 more were recorded here in the fortnight before it.

What the source measured

NASA FIRMS (VIIRS) reported 35 fire pixels with a combined fire radiative power of 110 MW, at nominal confidence, 23 km from Norfolk County.

The 35 pixels cover about 4.9 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.

Urban PEI: 20,656 within a heuristic 35 km radius; not unique people.

Wind from ENE at 38 km/h at 21:00 UTC, according to MET Norway.

At this point we have recorded a radiative power between 13.08 MW and 114 MW, over 184 readings since 31 August 2026. Today's reading sits 96% of the way up that range.

How we know

One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.

Our own score for this event is 39 out of 100.

This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.

Cascade Risks

air quality emergency

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.

This data is aggregated algorithmically from scientific sources. Not a replacement for official emergency warnings.
