While the shallow snowpack remains mostly supportable, it has left numerous obstacles like trees, stumps, rocks, logs, etc exposed or barely covered. A fall or loss of control while traveling on variable surfaces or merely running into something while moving at speed could result in equipment damage or bodily injury. Being observant and moving at slower speeds on more mellow terrain can help identify and avoid many of the obstacles. Avalanche activity will remain unlikely today. 

Early season represents a great time to practice avalanche rescue skills, route finding, and terrain identification. Practicing safe travel strategies now can help make them a habit for the rest of the year.

recent observations

Northerly aspects above 8600 ft in the Mt Rose backcountry and above 7800 ft. along the Sierra Crest hold the best coverage with more snow in the northern part of the forecast area. Numerous obstacles still poke through the shallow snowpack. Observations from Deep Creek and Tamarack Peak yesterday continued to show variable snow surface conditions. Observers have found scoured and wind-affected surfaces on wind-exposed slopes, patchy snow on sun-exposed aspects, and some soft surface snow (near-surface facets) in sheltered areas on northerly aspects.

Weather and CURRENT CONDITIONS
weather summary

The winds have decreased and should remain light through tomorrow. Calmer weather has allowed cold air to pool in the valleys and lower elevation temperatures are running cooler than those at the upper elevations this morning. This inversion should lift as the day warms up. After a sunny day today, some cloud cover may start to develop tonight and tomorrow ahead of a weak cold front forecasted to pass north of the region starting Monday.
