Another fire is burning inside the same view. Lac-363888 Fire started on Thursday 8 October, 2.5 miles east, and has reached an unrecorded size. Its heat is counted against it, not against this fire, and the pale ring on the map marks where it is recorded.

Smoke has been recorded lying over this ground ten times so far. The thickest of it was moderate between 1:10pm and 4:30pm local time. The last of those windows closed 23 hours ago, so what is overhead now is not known.

Where the heat is

No cluster large enough to call a separate front. The heat is in one piece.

Conditions measured 23.6 miles from the fire: 84°F, air at 15% humidity, a 11 mph wind out of the north.

How it got here

One day of record on a day-29 fire

The record here begins at 2:52am on 2 Oct and runs to 2:52am on 2 Oct — 0 hours, 1 readings of heat. The fire is on day 29, so the first 28 days are missing: nothing showed up from above until the fire was large enough and the sky over it clear enough for it to be seen. There is no long arc to draw yet. What follows is what has actually happened.
