Four other fires are burning inside the same view. Assist/Bdu/82A Fire started on Sunday 5 April, 1.5 miles north-west, and has reached an unrecorded size. Bdu/Juniper Fire started 2 minutes before this one, 2.3 miles south, and has reached 0 acres. Mtz/Bdc/82A Fire started on Thursday 1 October, 2.3 miles north, and has reached 0 acres. Vista Fire started on Saturday 3 October, 1.6 miles north, and has reached 1 acres. Their heat is counted against them, not against this fire, and the pale rings on the map mark where they are recorded.

Smoke has been recorded lying over this ground two times so far. The thickest of it was thin between 1:00pm and 4:30pm local time. The last of those windows closed 10 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 7.9 miles from the fire: 60°F, air at 39% humidity, a 11 mph wind out of the north-east.

How it got here

One day of record on a day-22 fire

The record here begins at 1:38pm on 25 Sep and runs to 2:42pm on 25 Sep — 1 hours, 10 readings of heat. The fire is on day 22, so the first 21 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.
