Winter storms help build the snowpack that help to fill our reservoirs and aid irrigators get through the hot and dry summer days. Anytime the early winter season brings big snow to the mountains bodes well for the snowpack season and the big snows in the west are still yet to come.
While not all basins have above normal snowpack there are many basins that are enjoying a good amount of early winter snow. The graphic below shows the snowpack conditions as of Sunday December 8th. The least amount of snowpack resides in the Pacific Northwest, note the basins in red (snowpack at 50% or less). Washington , Oregon and northern Idaho have had well below snowfall to date.
However, for all of the Rockies and the Sierra Nevada as well as the Desert Southwest, most basins have snowpack levels 90% or better with many basins over 100% of normal. Some basins in Arizona are 200 to 300% of normal so far.
While these current trends hold into the New Year. The answer is likely yes, at least through the rest of December and early January it appears the best snows will continue to be in the Rockies and the Desert Southwest with the Pacific Northwest still receiving below normal amounts of snow.
