Eastside Region

LOW avalanche danger exists at all elevations. Small wind slabs can be found in high elevation terrain that could be reactive to human triggers. Continue to be mindful of variable surface conditions in the backcountry.

Yesterday’s weather conditions were relatively benign in the high country of our forecast area with clear skies, mild temperatures and light to moderate winds out of the NE. We did not receive any reports of, or observe any blowing snow at any elevations. There are remnant wind slabs from previously strong winds on a variety of aspects, particularly above tree line. For the most part these slabs are small, scattered about and easy to identify. Beware of smooth panels of stiffer, hollow sounding snow overlying softer storm snow, or resting on loose, granular faceted snow. We have not observed any recent avalanches or received any reports of fresh slides, but remain vigilant in steep obstacle ridden terrain or on unsupported slopes where triggering even a small wind slab could result in a consequential ride. Increasing SW winds today will be strong enough to transport snow and could continue to add to the patchwork of wind affected snow.

Sunny aspects (E, S, W) in the Mammoth Lakes Basin warmed yesterday and surface snow became moist. This mostly created sticky, skin glopping conditions but we took it as an early warning sign of potential loose wet instabilities. Monitor warming snow for signs of potential instability such as rollerballs and pinwheels coming off of your tracks or originating near rock bands. Natural rockfall could also be an early indication of snow warming to concerning levels. If surface snow becomes punchy or unsupportive you are likely too late and should consider shadier, cooler slopes.
