![]() The Berkeley Labs analysis was published in the journal Nature Reviews Earth & Environment. The authors have called for more scientific analyses of snowpack loss to make more robust projections. Western mountain ranges, including the Cascades, could experience persistent low-to-no-snow by the 2070s, according to the analysis.

It defines a similar period of 10 years as “persistent low-to-no-snow.” ![]() The analysis defines as “episodic low-to-no-snow” a period of five years in which more than half a mountain range experiences 30% or less peak annual snowpack. The researchers reviewed hundreds of scientific studies, honing in on 18 of them to develop projections for when “low-to-no-snow” winters would arrive for several Western mountain ranges, including the Cascades. You can jump to a separate table for each region of the state: Oregon Coast, Willamette Valley, Cascade Mountains, Central Oregon and Eastern Oregon. “So you have a further disconnect in time between when your water is supplied and when water demands are higher.” The snowfall totals are annual averages based on weather data collected from 1991 to 2020 for the US National Centers for Environmental Information. “If you have your precipitation … predominantly falling in the form of rain instead of snow, your runoff from the mountains downstream to where all the water users are is going to be much flashier,” said research scientist and co-author Erica Siirila-Woodburn. In other words, snowpack is becoming much less of a sure thing. states of Idaho to the east and Oregon to the south, and the Pacific Ocean to the west. Lying at the northwestern corner of the 48 conterminous states, it is bounded by the Canadian province of British Columbia to the north, the U.S. Oregon’s most recent state climate assessment also projects that by mid-century, less than 25% of wet days every year will have snow. Washington, constituent state of the United States of America. Department of Energy, points out that the volume of peak annual snowpack is declining as the widespread burning of fossil fuels drives global warming. ![]() The analysis from Berkeley Lab, one of 17 national laboratories run by the U.S. Post Summary: Best Winter Hikes In Washington State And Where To Find Them. particular, the mean elevation of the early snow courses was. It’s a key predictor of how much water will be available throughout the dry months, especially in semi-arid regions east of the Cascades. of 1 April snow water equiv- alent (SWE) in the Cascade Mountains of Washington State.
