One more day of dry weather is expected today before a series of well advertised storm systems begin to impact the area Sunday. Mostly cloudy skies, moderate south to southwest ridgetop winds, and above freezing air temperatures are forecast for today. Southwest winds over the past 24 hours have mixed out the air temperature inversion that has occurred over the past several days. More information on the approaching storm systems, are available in this video briefing from the National Weather Service in Reno (click here).
No new avalanche activity has been observed or reported to have occurred since Wednesday. Observations made yesterday on Talking Mountain (Echo Summit area) on a N aspect at 8,730', on Waterhouse Peak (Luther Pass area) below treeline on a N aspect at 9,360', and in the Blue Zone (Outside the Bear Valley Ski Area boundary) below treeline on a NW aspect at 8,160' all indicated the presence of a stable snowpack (photos and pit profiles). Continued bonding and settlement of the recent storm snow has stabilized the storm snow instability that occurred on Wednesday. Views of the surrounding peaks revealed isolated wind transport occurring above treeline in the Carson Pass and Echo Summit areas, but minimal to no wind loading or new slab formation was observed yesterday in lee areas.
Avalanche concerns:
Wind transport that was observed yesterday from increasing SW winds continued overnight and may have caused sufficient wind loading to create a few small unstable slabs in isolated areas. If these slabs exist at all today, they will be found above treeline on N-NE-E aspects. For the most part, any areas of instability in the snowpack today will be few and far between. Use good travel habits to minimize the impact of any surprises.
