current conditions The Tony Grove Snotel at 8400' reports 33 °F and 2" of snow from yesterday evening. There's 101" of total snow, with 144% of average SWE (Snow Water Equivalent). A 10 mph southwest wind is blowing at the 9700' CSI Logan Peak weather station and it's 26 °F. Yesterday evening, south winds intensified and blew almost 30 mph for several hours, drifting snow into shallow stiff wind slabs at upper elevations. Today, clouds and cooler temperatures will help control wet loose activity, but it'll be sunny, warm and active again tomorrow.

recent activity Yesterday, 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. 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. |

Yesterday, observers reported triggering 1-foot-deep wind slabs at upper elevations in the Central Bear River Range. Drifting increased yesterday evening with south winds and stiff wind slabs formed or were enlarged on upper elevation slopes. Triggered avalanches are possible on slopes steeper than 30 degrees in drifted terrain at upper elevations.

Clouds and cool temperatures will help today, but triggered and natural avalanches entraining fresh loose wet snow are possible on steep slopes at upper and mid elevations. Sun and warmer temperatures on Sunday will cause heightened wet avalanche conditions on steep slopes with saturated fresh snow.
