Danger Rose Tutorial

We continue to have a mostly MODERATE danger in the backcountry. Isolated areas of CONSIDERABLE danger pocket the steep upper elevation northerly through easterly facing terrain. These avalanches - like this onein the backcountry between Alta and Brighton triggered on Wednesday - could have resulted in serious injury or death. Unmanageable human triggered avalanches remain possible. Heightened avalanche conditions exist on specific terrain features. Evaluate snow and terrain carefully.


Skies are mostly clear. Temps ride in the mid twenties. West to northwesterly ridge top winds are 30mph with gusts to 40. Mid-elevation winds are at 15mph. If you're looking for good weather and reasonable conditions, get it while you can - I expect we'll be in Avalanche Warning criteria by mid-week.


There were no reports from the backcountry yesterday. Little has changed however. We still have poor snowpack structure...with storms - finally - on the horizon. To look at the future, we need only look north. New Year's storms easily crushed the weak snowpacks of the Tetons and Montana. The result? - 3 fatalities in Montana and a few 'nine-lives' lost in the Tetons.


      Over the next 24 hours.

These persistent slabs have been around since before the New Year...a testament to the "historically weak" snowpack structure that will soon provide plenty of avalanches with the upcoming storms. Many of these hard slabs have been triggered remotely with pieces of the crown pulling back onto lower (<30 degree) slope angles. My backcountry route selections haven't changed in two weeks - I'm avoiding the steep northerly through easterly facing terrain above roughly 9500'. Other tracks on the slope or a single slope cut offers little security.


We'll have another beautiful day in the mountains. Temps will rise to near 40 at 8000' and the mid-30s at 10,000'. The winds should start to back to the west and southwest and blow 15-20mph with gusts into the 30s. Tomorrow will be even windier ahead of a vigorous and cold - if somewhat moisture starved - storm for early Monday. Don't worry about the lack of moisture. This first storm is only opens the door to a series of powerful wet, windy, and warm storms set for mid week.


If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following teams to alert them to the slide and whether anyone is missing or not. Rescue teams can be exposed to significant hazard when responding to avalanches, and do not want to do so when unneeded. Thanks.
