What impacts did you observe and what actions did you take during the 2025 water year (October 1, 2024 - September 30, 2025) due to abnormally dry or abnormally wet conditions? Please participate in the annual Pacific Northwest Water Year Impacts Survey: uwashington.qualtrics.com/jfe/form/SV_...
2024 Water Year Impacts Survey
Water year 2024 has now ended and conditions were warmer than normal and drier than normal for a majority of the Northwest, on average. How was the Northwest (Washington, Oregon, or Idaho) impacted? ...

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,...

Great article by Bob Henson on changing use of the term "heat dome," and the dynamics of heat waves. Includes a nice reference to the mechanisms of the June 2021 heat wave across the Pacific Northwest and our review on that event (doi.org/10.1175/BAMS...). yaleclimateconnections.org/2025/08/is-h...

The main driver of 2021’s Pacific NW heat wave was an extraordinarily strong, persistent high-pressure ridge, concludes a paper in #BulletinAMS by @occri.bsky.social and @larryoneill.bsky.social. Those most affected were older, low-income, living alone, and/or without a/c. bit.ly/3ZX3GHP
