bottom line Overall, the avalanche danger is MODERATE. There are areas with a CONSIDERABLE danger in the upper elevation northwest through northeast facing slopes approaching 40 degrees in steepness. Human triggered avalanches are likely in these locations, natural avalanches are not expected.

special announcement SKI AREA PREPERATION: Solitude - All of Solitude is now closed to uphill travel as they prepare to open more terrain to lift served skiing. Alta - Avoid the Supreme/Catherine's area as Alta prepares this area for lift served skiing. |

current conditions Temperatures continue downward with readings

recent activity The new snow was fairly active on Tuesday with lots of cracking and a number of shallow avalanches reported also. These involved weakness within the new snow for the most part but a couple of avalanches did remove all of the new snow exposing the previous faceted snow surface.

description
Even though the now buried faceted snow didn't seem to be all that reactive to the new load on Tuesday, I place this avalanche problem as the biggest concern today. I don't feel that the faceted snow has really showed it's cards yet. Very low density new snow and lack of wind are contributors to keeping the persistent weakness at bay. However, betting on facets to not avalanche is a loosing hand. |

description
The new snow should be less sensitive today after a night of settlement. This avalanche problem is fairly easy to manage as it is quick to show it's cards with cracking and instant results on small steep test slopes. Poke and prod any small steep slope to get a feel if the new snow is still sensitive. |
 |
weather It'll be cold today with temperatures remaining in the single digits and light northwest winds. Expect some clouds to move in with the chance of snow flurries with no significant accumulation. Cold temperatures and chances for flurries continue Thursday and Friday with another storm moving in on Saturday which may give us some more snow accumulation. |
