Forecaster: Evelyn Lees


We've got two avalanche education events this week – a FREE women's avalanche beacon clinic 9 am Monday morning at Alta, and a FREE avalanche awareness talk at the SL REI on Tuesday at 7 pm. Check out our calendar off the HOME page for more details on all the upcoming events.

Danger Rose Tutorial

The snow pack is mostly stable, and the avalanche danger is LOW. Watch out for rocks, and on steep slopes be prepared for shallow surface sluffing as you descend.


High pressure has brought clear skies and a temperature inversion to the Wasatch mountains. While drainage bottoms are in the teens and low 20's, 10,000' temperatures in the upper twenties to low 30's. The northwesterly wind speeds are generally less than 15 mph, with only the few highest peaks in the 15 to 25 mph range.

Cruising on the supportable low angle slopes and flats, it sounds like ripping Velcro - the muffled noise of the crust collapsing beneath this weeks 3 to 6” of snow. On steeper slopes and in wind scoured areas, it's a breakable crust, and riding conditions are a bit trickier. Considering we're recreating on snow depths of 12 to 30”, conditions aren't too bad, but be very careful to avoid hitting rocks and logs.


No avalanche activity has been reported from the backcountry for the past several days.


      Over the next 24 hours.

We've got quite the set up for the next big storm – cold, loose surface snow sitting on a slick crust, above more layers of thin ice crusts and small angular facets. With out any new snow, the avalanche potential today is limited to the triggering of shallow sluffs on steep slopes. I would imagine you could also dinner plate out a few patches of the ice crust if you're getting into very steep terrain. Quick hand pits today will give you a good feel for the current layering, and with the good visibility, be observant of the present snow coverage.


High pressure building into the area will bring clear skies and a warming trend to the mountains today. 8,000' highs will be in the mid 40's, and 10,000' highs in the upper 30's. The northwesterly winds will remain light, generally less the 15 mph. Sunday will be just a bit cooler, with partly cloudy skies. A small storm is forecast to cross the area Monday, with high pressure building right back in for mid week. The current buzz is pattern change is in the works for next weekend.
