current conditions The Tony Grove Snotel at 8400' reports 24 °F and 3" of snow from yesterday. There's 104" of total snow, with 143% of average SWE (Snow Water Equivalent). A 20 mph west-northwest wind is blowing at the 9700' CSI Logan Peak weather station and it's 17 °F. Drifting from west winds last night and today is creating heightened wind slab conditions at upper elevations, and warming temperatures and sun will cause heightened wet avalanche conditions in sunny terrain and at mid elevations.

recent activity Friday, observers reported triggering several shallow wind slabs on drifted upper elevation slopes in the Central Bear River Range. They also noted a few sled triggered wind slabs and small wet loose avalanches in the area. Observers report triggering a few small wet avalanches above the Providence Quarry Saturday evening. Friday we intentionally triggered predictable wet loose sluffs in State Line Bowl in upper Sink Hollow. The slow moving avalanches were easily triggered from above, entrained a few inches of saturated new snow and made large piles of heavy debris. |
