since anything was last seen giving off heat — about 12:55pm on Wednesday, local time.

49% more

energy in the last 0.5 hours of the record than in the 0.5 before them — the fire was hotter when it was last seen.

8.2miles

is how close the heat has come to Piñon Hills at any point in the record. In the last day the nearest heat has been 8.2 miles from it, and the closest this fire has come to Adelanto is 8.7 miles, 8.7 in the last day. The two figures are the same because the record is barely a day long: the last day is very nearly all of it.

0.5miles

is the furthest any heat has been seen from the point on the official record — the width of the ground involved so far.

One larger fire is burning outside this frame: Summit Fire 8.8 miles south-west at 2,690 acres. None of their heat is counted here.

Smoke has been recorded lying over this ground five times so far. The thickest of it was thin between 1:00pm and 4:30pm local time. The last of those windows closed 182 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 5.9 miles from the fire: 58°F, air at 38% humidity.

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.
