These observations document past conditions at a small and variable scale. They are not to be confused with an avalanche forecast. They come from a variety of sources. We can only vouch for the quality of those produced by the SAC forecasters and professional observers.

Avalanche Observation 		Incline Lake Peak
Mount Rose Area 		Shallow wet loose activity on an ESE aspect on Incline Lake Peak Small roller balls of wet loose snow on the E side of Fireplug Wet snow instabilities on the flanks of Relay Peak Snowpit work on a NE aspect did not reveal any signs of instability. Wind sculpted surfaces near the summit of Incline Lake Peak Today felt spring-like, with sunny weather and warm temperatures on Incline Lkae Peak. The winds decreased and shifted to the SW around noon. During our tour, trees started dripping, and the snow surface started to get wet on sun-exposed areas on all but the N aspects. We noticed several small roller balls and sluffs of wet loose snow near rocks and on SE and S facing slopes. Some happened today as the day warmed up, and some happened yesterday. At the end of our tour, we drove over Mt. Rose Summit and saw Runnels forming in the snow on a SE facing slope as the day warmed up. Forecaster
