In sintesi

Today, the Avalanche Hazard in the West Central Mountains is Moderate. Human-triggered avalanches are possible. 6-10 inches of light snow and gusty winds have loaded leeward terrain, creating slabs 6-12 inches deep that are resting on slick crusts. Avoid wind-loaded, steep terrain, especially below cornices that may be sensitive to the weight of a person.  The Sun will be out today heating up the snow surface for the first time which will likely cause wet-loose avalanches in the form of point releases and rollerballs. Avoid slopes that are steep and are getting heated by the Sun enough that you are noticing rollerballs or point releases. Choose another aspect that is cooler, and is not under direct Sun.

    Yesterday, the wind did a good job of moving snow, creating fresh cornice lips, and loading leeward slopes which has likely created slabs that may be resting on a slick crust and are sensitive to the weight of a skier or rider. Last night the Granite Mountain weather station recorded gusts that almost reached 30 MPH.

    Today, North winds are forecasted to be moderate, which is perfect to form new wind slabs. Local terrain can influence wind direction, so look for clues of drifting and sculpting around you as to which way the wind has pushed the snow. If you hear hollow sounds or sounds of collapsing and whoomphing or see cracks in the snow surface, choose another route.

    Yesterday the wind made some fresh lips off the cornices on the East side of Bruin, and sculpted waves on the surface of some exposed slopes on multiple aspects, swirling around the terrain.

    Full Sun is hard on snow, especially in March. Expect to see some natural wet-loose avalanche activity as our new blanket of snow gets heated from the Sun. East, South, and West aspects steeper than 30 degrees are going to shed snow, especially rocky areas... If you are producing rollerballs or noticing natural activity, choose another slope aspect that is cooler, and not getting direct sunlight.

Avalanche Discussion

The new 6-10 inches of snow over the past few days has brought back winter, but the Spring Sun is coming out to change things once again. Our new snow is resting on slick crusts, and not bonded well on steep Solar aspects. Below the new snow, the bonding of recent saturated layers is pretty good, and the snow below is hard. For now, we are concerned with the new snow, that has formed variable wind slabs and loose avalanche problems.  

We would love to hear from you...If you see or trigger avalanche activity, please take the time to snap a picture and note the approximate elevation and aspect, you can submit an observation on our website. Getting your info helps forecasters and other users get a better picture of the conditions throughout our mountains. If you have trouble using our observations page, please email us at: [email protected] Please be mindful of other users in the mountains, and where you are at. There are closures for motorized travel in and around the local ski areas, in the Lick Creek Canyon,  Granite Mtn, Jug Mountain, and other areas throughout our region.  Check out the Winter Travel Map to find out where you can shred on your sled or moto.  Not all of these areas are signed, it is your responsibility to know where these closures exist.  

***We will issue our last advisory for the season on Saturday, April 10th. We would like to thank everyone for their support and observations, and for staying safe during an especially dangerous winter!
