Although we’ve technically had a break in storms, it
may not seem like it. Since 6:00 am
yesterday, we’ve had another 1 to 1.5 feet of new snow with upper
The turning and riding conditions have a wide range from scoured sustrugi to thick slabs of chalk-like wind hammered snow, to blissful light density powder. Likewise, the trailbreaking varies on where you go, from effortless to nearly impossible. The best bet for today will be sheltered lower angle slopes with the fast, light density new snow.
We have issued a special avalanche bulletin over the weather radio and media.
With 1-2 feet of new snow combined with strong winds, we have a text book recipe for avalanche activity and you will need to avoid any steep slopes with deposits of wind drifted snow. You can recognize these by their smooth, rounded shape, slabby feel and hollow drum-like sound. Look for, and avoid, telltale cornices with fat wind deposits of new snow beneath them.
Sharp avalanche eyes will be mandatory today, as the snowpack is in a complex frenzy of transition. If you mistakenly wandering into a high elevation, wind loaded slope, you will most likely trigger an avalanche, but if you stay in wind sheltered, lower angle areas, you will find the best turning and riding conditions, as well as fairly stable snow. Watching your slope angles will be critical today as the new snow is sluffing easily, but not moving far on slopes less steep than 35 degrees.
With a substantial snowpack all the way down to 5,000’, snow-shoers, ice climbers and winter campers will need to watch out for terrain traps in gullies and large collection zones above them.
Bottom Line (
The avalanche danger runs the gamut from HIGH in steep, upper elevation, wind loaded areas, to CONSIDERABLE on slopes steeper than 35 degrees with recent deposits of wind drifted snow, to MODERATE on sheltered slopes less steep than 30 degrees.
The current storm system will continue to split with a weak mid level through moving through at about mid day. The temperatures are at a 24 hour high as of 6:00am in the low to mid twenties and the wind has decreased as it shifts from the SW to the west. Today will be mostly cloudy with a chance of another 2-4 inches of snow in the Cottonwood Canyons, most likely in the morning. Wednesday should continue mostly cloudy with a chance of a trace to 1” of snow during the day and 8,000’ temperatures in the upper 20’s. The weather will start to shift Wednesday evening with an increasing chance of snow, temperatures in the low 20’s and SW winds at 20-30mph.
