Winter storm watch in effect late tonight through Wednesday morning: 9″-16″
JACKSON, WYO – Given the swing and a miss of the last big storm cycle many locals are wondering if winter is ever going to show up this year?
In my 25 years of forecasting the weather for Jackson Hole and the Teton Mountains, I have never experienced a forecast period that was as big a bust as this past week. Between the Christmas and New Year’s Weekends, as much as two feet of snow was forecast, and less than 6 inches accumulated.

Snow pack wise we are in relatively good shape compared to our neighbor resorts in Colorado, Utah and California. With SNOTEL data showing the Teton Snow pack to be in the 90% – 109% range. Areas of Utah, Colorado, and California are well under 50% of average.
Jackson Hole Mountain Resort snow total chart shows us clearly in the lead regionally and being inched out only by Whistler up in BC.
Warning: Persistent slab Weak layers in our snow pack ( 1/8/18) :
At the mid and upper elevations cohesive slabs sit upon a buried weak layer of faceted snow that lies atop a hard crust. This problem layer and bed surface can produce human triggered avalanches two to four feet deep on a variety of aspects, but has been most active on north through east to southeast aspects. At the lower elevations, backcountry travelers might be able to trigger an isolated pocket of soft slab in very steep gullies and ravines.
This is an Extended Column Test performed by Grand Teton Rangers on 25 Short. The weak, faceted snow that the upper block fails on is typical of most snow slopes at most altitudes and aspects in the region. We rarely see such a dangerous problem so consistent and widespread.
