Elevated freezing levels expected into Thursday with minimal refreeze overnight.This may trigger deeper instabilities.
follow 511 for most up to date road closures.
Watch for wind slabs in cross-loaded features and further down the slopes than usual due to wind intensity. Our team is more concerned about this problem in the tree line elevation band.
Warm temperatures may increase reactivity of this layer. Persistent slabs sit over different weak layers depending on elevation & aspect. Investigate these layers before committing as there is a lot of variability dependent on aspect and elevation.
With rising freezing levels watch for wet loose avalanches. Minimal overnight freeze expected on Wednesday night, do not count on recovery of the surface snow on Thursday.
Moist surface snow with rising freezing levels and warm temperatures persisting into Thursday. Strong SW winds have stripped exposed alpine to rock. We expect wind slabs in crossloaded features and into tree line. Several December faces layers can be found in the midpack. Facets and depth hoar are formed near the ground.
Road Patrol did not observe any natural activity today. On Tuesday one large wind slab avalanche was noted on Fluted Peak on a south facing feature.
