Explosive Emigrant fire reburns forest, forms heat-fueled cloud
The Emigrant Fire, now the largest in Lane County this year, has scorched about 3,500 acres. Watch a time lapse of the pyrocumulus cloud it formed over the Willamette National Forest.

The Emigrant Fire in the central Oregon Cascades has burned over 6000 acres at this point in an area that has received record or near-record low precipitation since April 1st this year (based on 45 years of data), as shown by nearby SNOTEL stations.

New work by Levine et al.: In the northern Sierra Nevada, private industrial forests tend to be denser and more homogenous, and to have more high ladder fuels, than public forests. This leads to a substantially higher probability of high severity wildfire. doi.org/10.1111/gcb....
Extreme Weather Magnifies the Effects of Forest Structure on Wildfire, Driving Increased Severity in Industrial Forests
Wildfires are consistently more severe in private industrial forests than public ones. In this paper, we identify the drivers of this pattern. Namely, we show that fire severity is elevated in dense,...

Read about snow monitoring options with greatest potential return on investment in this new publication from our colleague Mark Raleigh.
My latest research on snow monitoring and water supply forecasting has just been published with @springernature.com in Communications Earth & Environment (@commsearth.nature.com). We found greater improvements from measuring snow in the "right places" rather than everywhere. Read here: rdcu.be/eASXF
Snow monitoring at strategic locations improves water supply forecasting more than basin-wide mapping
