Good morning, this is Sue Burak with the Inyo National Forests Eastern Sierra Avalanche Centers advisory for the Memorial Day weekend. MOUNTAIN WEATHER It was only 5 days ago that temperatures were close to 70F in the high country, wet sluff avalanches were common, streams were flowing high and getting close to peak flows. There were red flag fire warnings in the Owens Valley. A couple of days ago, winter decided to come back with a vengeance with highs in the upper 20s and low 30s and strong northerly winds. For the next three days, expect more winter weather with highs in the mid to upper 20s above 10,500 ft. and around 32 F at the 9,000 to 9,600 ft elevations. There is a 70% probability of snow today at the higher elevations with diminishing showers tonight. Tomorrow will be snowy again and depending on the location of the low pressure system, snowfall could be heavy in localized areas around thunderstorms. Northerly winds have shifted to the west and there are no wind advisories expected for the rest of the Memorial Day weekend. SNOWPACK AND AVALANCHE DISCUSSION Winter conditions prevail at the higher elevations. A few inches of new snow can be found above 10,000 ft and I found wind drifts up to 6 inches up Rock Creek. Skiing is on hard, irregular surfaces- imagine the deep and wide suncups of last weekend being frozen hard and unforgiving. This is not a nice picture for weekend ski descents. For those die hards looking for powder, check the bonding between the old hard spring snow and the new wind drifted snow. With diminishing wind speeds, there will be much less wind drifting of new snow today and over the weekend. Cloud cover and a cold air mass will keep the snow surface from softening much over the next two days. The avalanche danger rating is LOW. BOTTOM LINE The avalanche danger rating is LOW. Please note that the avalanche danger rating in this advisory expires in 24 hours. This advisory is our best interpretation of snow pack conditions and NWS forecasts issued today. Backcountry travelers should be aware that elevation and geographic distinctions are approximate and that a transition zone exists between upper and lower elevations. Avalanches do not happen by accident and most human involvement is a matter of choice not chance. Most avalanche accidents are caused by slab avalanches that are triggered by the victim of member of the victim's party. Even small slides can be dangerous. Always practice route finding skills and carry avalanche rescue gear. Remember that avalanche danger ratings are only general guidelines. Distinctions between geographic areas, elevations, slope aspects and slope angles should be made.
