Radical Western Snopack Decline

New study: Snowpack levels show dramatic decline in western states,
Oregon State University, March 2, 2018.

"...long-term snow monitoring sites in the western United States found declines in snowpack at more than 90 percent of those sites - and one-third of the declines were deemed significant."

"Since 1915, the average snowpack in western states has declined by between 15 and 30 percent..."

"In many lower-elevation sites, what used to fall as snow is now rain. Upper elevations have not been affected nearly as much, but most states don't have that much area at 7,000-plus feet."

"The solution isn't in infrastructure. New reservoirs could not be built fast enough to offset the loss of snow storage - and we don't have a lot of capacity left for that kind of storage. It comes down to managing what we have in the best possible ways."

"The researchers attribute the snowpack decline to warmer temperatures, not a lack of precipitation."

"...data from 1,766 sites in the western U.S., mostly from the U.S. Department of Agriculture's Natural Resources Conservation Service and the California Department of Water Resources."


Corporate Press

Study: Snowpack has declined dramatically across US West,
AP, March 2, 2018.

"Scientists in Oregon and California have found dramatically declining snowpack across the American West over the past six decades, according to a study published Friday."

"The study appeared in NPJ Climate and Atmospheric Science and was a follow-up study to one completed in 2005. This analysis found the loss of snowpack has accelerated."


"...snowpack levels in most of the western U.S. for 2017-18 thus far are lower than average - a function of continued warming temperatures and the presence of a La Niña event, which typically results in warmer and drier conditions in most southwestern states."

About All This

My observations indicate it is raining more. I mean that tropical activity along the Equator has picked up, and the Equator is sending out more, and more fierce outbursts of superheated tropical moisture Northward. A lot of them hit us last year. But where they "traditionally" go, the "normal" cycle of weather in our corner of the NE Pacific has been radically changing. I attribute a lot of this to the shape of the atmosphere itself changing with the rising heat. The bulge of warm air wrapping around the Equator has bloated out. The annual interfaces between warm and cold have changed their lattitude and timing.

California and the Sierra are experiencing more and much stronger tropical influences than ever before.

My projection is that the dry grasslands currently running up the West Coast from above Matazlan to just below Monterey, Ca, are in the process of marching relentlessly further North under drying and warming skies with the new weather patterns spawned by the bloating out of the Equator.
I figure the temperate rainforests tha are currently running South on a narrowing wedge from Southern Oregon, down to terminate at Monterey, will all be pushed up to 900 miles further North, at least up to the center of Oregon, as the Equatorial-Dominated weather pattern expands Northward, and takes over all the season of the year up to 40 degrees North, over the next very few years.

The trees are not going to "move" over the next few years, but the weather that supported the current distribution of temperate coastal forests in California already has, has have the conditions in the Sierra's great Pine and Fir forests.

The weather's already radical changes look to be accelerating.

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

If you feel these efforts are valuable, I'm cordially inviting you to support them, here:



I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
