Use heightened awareness while traveling in avalanche terrain & always carry the Trifecta of rescue equipment & bring a savvy partner. Be hesitant of overhanging cornices on slopes above you, they can trigger large avalanches. Some Southerly aspects may have loose wet snow which has been effected by sun. Many subsurface objects & streams are reappearing.
Surface hoar has been typically found in the mornings & degraded by afternoon sun, with the largest feathers found in riparian cavities & lower elevations. At treeline & below the SH, near surface facetting has occurred & in some locations creating a plyable surface skin with loose grains underneath. Although higher in the alpine a supportable surface windpack has a similar NSF layer. The BWRA & VLakes areas both had a facet layer 20-30cm deep that was acting as an interface that could fail with MOD to HARD forces.
Yesterdays observations yielded adequate but dwindling coverage & a mostly stable snowpack for the BWRA & Virginia Lakes. An avalanche above Leavitt Lake in the Cirque was noticed to have possibly released sometime on Tueasday. The origin of the slide was from a break in the looming cornice on the most NW portion of the feature. The cornice mass collapsed onto a previously wind loaded slab sending a R1D2 avalanche almost 600' towards the lake edge. NC-O-R1-D2 Chunks the size of rerigerators are still in tacts throughout the debris.

A pleasant day in the mountains yesterday with abundant sun & no wind. Temperatures are inverted this morning with both Snotels reading above freezing. Unseasonably warm temperatures & a lack of precipitation for over a week is about to end as a low pressure system enters Saturday morning. Mountain snowfall could be heavy at times & visibility will be shallow due to strong South winds & gale force gusts. A robust line-up of Pacific storms may inundate us with precipitation of many forms throughout the next 7-10 days.
