Warm and mild temperatures today could allow for wet snow instabilities to form on sun exposed terrain at all elevations.  Wet snow instabilities ( roller balls, pin wheels, and/or small sluffs ) are expected to be mainly small in size and start to develop during the midday hours.  Firm crusts may exist in some wind scoured terrain that may pose fall and travel hazards.

Practice safe travel protocols to reduce your risk in the backcountry.  Have a travel plan, avoid areas of concern, and communicate effectively within your group.

recent observations

*  Observations from Incline Lake Peak ( Mt. Rose area) showed a mix of snow surfaces.  On northerly aspects, wind scoured snow existed in upper elevation areas, with slow and sticky snow in lower elevation terrain by midday.  Southerly aspects had 3-4'' of wet snow on top of supportable snow by late morning.

*  Good riding conditions were reported from the Independence Lake area.  Soft snow on top of a supportable base was found above 7500' on N/NE aspects.
