The snow water equivalent percent for the Western U.S.
A large portion of the West has less than 50% of the NRCS 1991-2020 median. Some good storm systems are needed to deepen the snowpack.
#SnowPack
Snow water equivalent map for the West. The areas in red have less than 50% of the median SWE for this point in the year.
Snowpack in the West is lacking as shown by the snow water equivalent. Many basins across the West have snow water equivalents below 50% of normal shown in red.

Colorado ski areas battle historic snowpack shortage with artificial snow
Colorado is experiencing its third-worst start to fall and winter on record for snowpack levels, forcing ski areas to rely even more heavily on snowmaking operations to open runs for the season. This early in the season, ski areas usually only open runs where manmade snow helps cover the runs. However, this year, there has been virtually no natural snow in Colorado's high country for several weeks to start the winter ski season.
A good read about the problem of #drought in #Canada
Did you know that the #snowpack in #britishcolumbia is 13% of normal?
This is what happens when there is not a proper #snowpack... but, hey, isn't it awesome to be outside without a jacket in January?
Low water levels in Québec rivers spur navigation warnings, watering bans, etc. https://www.ctvnews.ca/montreal/article/low-water-levels-in-quebec-rivers-spur-navigation-warnings-watering-bans/ #climatechange #cdnpoli #polcan #polQC #QCpoli #polMTL #MTLpoli #noplanetb #nowayback #nowayout
Thank you for the #intel!
The decorative lampposts sound lovely, but yeah, not helpful for the problems of heat and #asphalt.
The thing is, that even in advance of #HeatDomes and serial #heatwaves neighbourhoods like mine are unwalkable in the summer from heat alone.
In the winter, the sloped sidewalk concrete that almost-seamlessly joins the asphalt roadway AND lack of routine snow clearance means that street parkers are often parked somewhat on the sidewalk itself.
This is particularly easy to do when the #snowpack on the road is higher than the sidewalk, which is most winters, even ones with relatively little snow.
This narrows the sidewalks to the point that even if cleared, they are not necessarily wide enough to use with #AssistiveDevices such as #rollators and #wheelchairs.
I really want #yegAccessible, year-round!

Why #climate researchers are taking the temperature of mountain #snow
As climate change fuels increasingly erratic #weather, #scientists need a better read on #snowpack temperature to understand when water will reach reservoirs—and when it threatens to flood them. https://www.technologyreview.com/2025/05/14/1116395/why-climate-researchers-are-taking-the-temperature-of-mountain-snow/

Colorado River snowpack takes major dive; streamflow projections lowered
"Since April 9, when snowstorms pushed snowpack from 91% to just over 100% in a single day, conditions have changed dramatically and levels have fallen to 70% of normal as of Friday, April 18."
"A study of tree rings in the Gaspesie's Sainte-Anne River area reveals that snowpacks have been declining noticeably in the region's mountains for nearly nine decades. The researchers say the phenomenon is directly linked to global warming.
They add that the decline in #snowpack has significant implications for #water management and regional wildlife."

More drought worries as unusually dry January leaves B.C. snowpacks depleted
The B.C. River Forecast Centre's Feb. 1 snowpack report confirmed what many have already observed: January was unusually dry.
