In sintesi

Avalanche danger is LOW.  Hazard may elevate to MODERATE this evening into tonight for WIND SLAB on NW-N-NE-E-SE aspects at all elevations. Be on the lookout for fresh building slab on leeward terrain if snowfall and winds intensify earlier than expected during the day.

    Trace to no new snow amounts were recorded this morning across the forecast zone as the first of two weak upper troughs pass the area. The stronger of the two is predicted to impact the area after 5pm and with it increased snowfall (1-4”) and strong to extreme winds that will shift from predominantly southwest flow to westerly flow. This wind slab problem is more a pre-emptive “heads up” in case snowfall and winds pick up earlier than expected today. Evaluate for fresh building wind deposits on leeward terrain adjacent to ridgeline, gullies and convex rolls. New snow will be falling on firm and slick old snow surfaces that could make it sensitive to skier trigger. Look for signs of wind transport and wind slab development by identifying areas of blowing snow, cracking or new snow sluffing under your feet.

Avalanche Discussion

A grey-bird day is on tap with the best chance for some new snow this evening into tonight. Flat light conditions and the overall degraded state of the old snowpack will make for some challenging conditions today. Although predicted snow totals are not that great, anything will be appreciated and let’s hope we fall on the high end of totals come this weekend. If you are heading out today, be aware of changing conditions and be prepared if the real meat of this little storm rolls in earlier than expected. The full gamut of ski mountaineering equipment is a “must have” to safely and efficiently travel on a very firm and wind sculpted snowpack in the Eastern Sierra. Ski and boot crampons, ice axe, and helmet are key.
