The picture as of 10:09am today

The Event Fire is still listed as active, and has not been looked at lately. Nothing has given off fresh heat for 956 hours. There is no clear movement in the last six hours: the middle of the heat has shifted less than the width of the ground a single reading covers.

No fresh look at this fire for 956 hours. Everything on the map below was seen before then.

Four other fires are burning inside the same view. Candle Fire started on Wednesday 12 August, 1.4 miles south-west, and has reached 64 acres. Needles Fire started 15 minutes before this one, 1.4 miles south-west, and has reached 6,018 acres with 14 people assigned. Phahin Fire started on Tuesday 11 August, 3.3 miles south, and has reached 26 acres. Rancher Fire started on Tuesday 11 August, 2.0 miles west, and has reached 504 acres with 2 people assigned. 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 six times so far. The thickest of it was thin between 2:10pm and 5:30pm local time. The last of those windows closed 121 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 2.7 miles from the fire: 47°F, air at 81% humidity, a 22 mph wind out of the north.

How it got here

Two days of record on a day-42 fire

The record here begins at 12:53pm on 4 Sep and runs to 1:38pm on 5 Sep — 25 hours, 125 readings of heat. The fire is on day 42, so the first 40 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.

Each bar is one hour of local time, sized by how much energy the fire gave off in it. This fire is too young for a day-against-day comparison to say anything, so the hours are shown instead.
