Weather & fire-spread conditions

No Red Flag Warning. The National Weather Service hasn't flagged this area for dangerous fire-spread conditions right now.

Hot, dry, and windy weather can help a fire grow; cool, calm, or wet weather helps crews. The tags below rate each day for fire spread — green is calm, red can push a fire.

A general fire-weather guide (wind matters most, then how dry it is, then heat), not a prediction of what a specific fire will do.

Could this fire move fast?

Weather isn't the only thing that changes how a fire moves. The ground matters too: how steep it is, and what's growing on it. These four numbers are for the exact spot where this fire started, not the whole fire. A big fire crosses a lot of different ground.

0° slope

Fire usually moves faster uphill than downhill. Heat and flame lean uphill, drying out the ground above the fire before it gets there.

Shrub (SH1)

Low shrubs and dead shrub litter, about a foot deep, maybe some grass. Fire moves slow, with short flames.

0% tree canopy cover

The more tree cover above a fire, the easier it is for the fire to climb from the ground into the treetops. That's called a crown fire. Crown fires move faster, throw embers farther ahead of the fire, and are harder for crews to stop head-on.

5,416 ft elevation

Elevation by itself doesn't make a fire more or less dangerous. But it shapes the other three numbers here: what grows there, how dry things get, and what the weather does.

Elevation and slope from the USGS 3D Elevation Program; fuel type and canopy cover from LANDFIRE (USGS and U.S. Forest Service), pulled Thursday, September 10th at 3:44 p.m. CDT.

Who's on it

About 124 people are assigned to this fire, run by a Type 3 IC. The government rates it a Type 3 Incident. About $82 million has been spent on it so far.
