Danger Rose Tutorial

Today the avalanche danger is mostly Low (Level 1) but with pockets of Moderate (Level 2) danger for one of four different types of avalanche dragons 1) wind slabs, 2) wet avalanches, 3) deep slabs and 4) large cornices.


This is the time of year where people start being more interested in the the 3 G's than the 3 S's--Groomers, gardening and golf instead of snowmobiling, skiing and snowboarding. But those lucky enough to get out yesterday had a spectacular, warm, sunny day where you could revel in the great gift of just being alive in a specacular place with specacular weather. You almost did not mind the poor and extremely variable snow conditions--sun crusts, a wide variety of mush, punchy wind slabs and sastrugi. But If you found the right spot, it was actually quite good.

Overnight, winds have come up to around 25 mph from the southwest. Clouds overnight kept temperatures warm and they are right around freezing this morning and we're expecting mosly cloudy with light snow showers today.


In the Salt Lake area mountains, there was a couple human triggered avalanches. A skier intentionally triggered a fresh wind slab on Tuscarora Peak (on Seagull) 1' x 70', which ran down quite a ways and he found a smaller wind slab partway down. This was from the strong winds a couple nights ago.

A skier triggered a sizeable wet sluff on the southeast aspect of Superior at 11 am, which also ran down fairly far.

FYI, some large slabs occurred in the Logan area mountains yesterday and you should check out their advisory or the Current Conditions for those.


      Over the next 12 hours.

We should be building a new round of fresh wind slabs today with 1-3 inches of new snow combined with wind, which should begin mid day and continue through afternoon. These will be mostly shallow and soft. As always, avoid steep slopes with recent wind deposits, which will look smooth and rounded and often feel hollow or punchy.

Note: the cornices are huge and sensitive these day and they are breaking farther back than normal. As always, never walk up to the edge of a dropoff and travel well on the upwind sides of ridges.


      Over the next 8 hours.

Because of the cloud cover overnight, temperatures are still near freezing this morning and not nearly as cold as yesterday morning. So even though we will have mostly cloudy skies today with cooling this afternoon, we still need to think about wet avalanches today.


      Over the next 24 hours.

Several big, deep slabs have occurred in the Logan area mountains over the past few days including yesterday. These are most likely deep, dry slabs triggered by heating. I suspect there may be places in the Wasatch Range where these can occur as well. They are low probability but with high consequences and it's always hard for the human brain to grasp these "black swans", rare, impossible to forecast but with huge consequences.


We should have mostly cloudy skies with light snow showers starting around mid day. We should get 1-3 inches of snow--mostly in spring squalls. Temperatures are near freezing this morning but they should drop into the teens tonight with the arrival of the colder air. Winds should pick up to 30 mph with higher gusts as the squalls pass and winds should turn from southest to northwest throughout the day.

We should have a rest day on Tuesday with a stronger impulse arriving Wednesday and Thursday, which should give us about a foot of snow.


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.
