    A good overnight refreeze is expected to have occurred last night due to near to below freezing air temperatures and radiational cooling under clear skies. Areas of wet surface snow will form again today in response to daytime heating. The snowpack is expected to remain supportable well into the afternoon hours. Any human triggered loose wet snow instabilities such as roller balls or tiny loose wet avalanches are expected to be small, inconsequential, and not present a significant hazard to backcountry travelers.

Avalanche Discussion

Observations made yesterday on Rubicon Peak (West shore Tahoe area), Angora Peak (Echo Summit area), and on Incline Lake Peak (Mount Rose area) all indicated that stable snowpack conditions with minor amounts of wet surface snow lasted well into the afternoon hours. From noon to 4 pm, 2 to 4 inches of wet surface snow existed on top of supportable melt-freeze crust. Wet surface snow was noted on NE-E-SE-S-SW-W-NW aspects at nearly all elevations and on N aspects below 8,500'. Patches of transitional snow were noted on N aspects above 8,500'. Any areas of human triggered wet snow instabilities were very small and inconsequential.
