Another fire is burning inside the same view. Veg/Jn/Lra Fire started on Tuesday 25 August, 4.5 miles east, and has reached 0 acres. 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 three times so far. The thickest of it was thin between 1:10pm and 4:30pm local time. The last of those windows closed 48 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 9.7 miles from the fire: 95°F, air at 23% humidity, a 6 mph wind out of the south-west.

How it got here

One day of record on a day-5 fire

The record here begins at 3:58am on 24 Aug and runs to 3:58am on 24 Aug — 0 hours, 2 readings of heat. The fire is on day 5, so the first 4 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.
