Conditions measured 0.7 miles from the fire: 78°F, air at 18% humidity, a 18 mph wind out of the north.

How it got here

19 days of record on a day-42 fire

The record here begins at 2:11am on 5 Sep and runs to 3:21am on 25 Sep — 481 hours, 79 readings of heat. The fire is on day 42, so the first 23 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.
