Danger Rose Tutorial

Most terrain has a Low to Moderate avalanche danger. There are scattered areas with a Considerable avalanche danger which include the steeper northwest through northeast upper elevation terrain. Watch for freshly drifted snow which could overload the buried weak layers. Also, watch for sunny slopes to become damp and possibly unstable later today.


Under partly cloudy skies, temperatures dipped into the low teens overnight and we have light northwest winds that have increased just slightly over the last few hours. Riding conditions remain excellent on many aspects with heat damage to the southerly aspects.


A number of shallow soft slab avalanches were triggered by people in the backcountry on Thursday. It sounds like most were heat related, occurring on sunnier slopes. The largest were 50 feet wide. These were manageable for the most part, not posing a whole lot of threat for experienced travelers. There were also a few heat initiated loose snow avalanches reported with a couple producing fairly good sized debris piles. These packed a bit more punch and could pose a threat if you’re in the wrong place.


      Over the next 24 hours.

The biggest threat remains an avalanche breaking into old weak snow near the ground although it seems like this issue is dormant at the time being. This being said, savvy people are still quite leery of many slopes out there. Also, watch out for what the wind does today as far as adding new weight to a slope.

Here are some excellent observations detailing poor snowpack structure from some of our high end observers:1 LEES, 2 GAGNE, 3 NALLI


      Over the next 24 hours.

The little bump in wind speeds is enough to make mention of some fresh drifts that may be forming and may be sensitive to a person. There’s plenty of loose powder to blow around and form some fresh slabs. Buried surface hoar may act as the weak layer making this issue more dangerous. The wind will blow from the northwest so pay close attention to fresh drifts on easterly aspects as well as any cross loaded terrain feature.


      Over the next 8 hours.

Heat related activity should again be considered today. It probably won’t be as pronounced as on Thursday but should be expected again. Stay out from underneath steep slopes that are receiving direct sun.


We’ll have partly cloudy skies with temperatures up around 30 at 8000 feet and 20s along the ridges. Winds will be slightly gusty from the north and northwest in the moderate speed range. We are still anticipating a storm impacting us mainly on Sunday that should bring a nice refresher. Check our noon mountain weather forecast for more details later today.


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.
