A new University of Washington study finds that climate warming is likely to complicate avalanche forecasting across the Pacific Northwest by increasing rain‑on‑snow events that create unstable ice crusts within snowpacks. While avalanche forecasters in warmer, maritime regions like western Washington are accustomed to these conditions, colder inland areas such as Eastern Washington, Idaho and Montana may face greater risk as their snowpacks begin to resemble coastal patterns. Using 25 years of regional data and climate simulations, researchers found that…
