    A strong overnight refreeze is expected to have occurred again last night due to near to below freezing air temperatures and radiational cooling under clear skies. While 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 and inconsequential, not presenting a significant hazard to backcountry travelers.

Avalanche Discussion

Observations made yesterday on Mt. Lola (Independence Lake area) and on Castle Peak (Donner Summit area) fell right in line with other recent observations from around the forecast area. A strong snow surface refreeze had occurred overnight with no evidence of residual wet snow lingering from previous melt cycles. At noon, 1 to 3 inches of surface wet snow on top of supportable melt-freeze crust was observed at all elevations on E and SE aspects. As the afternoon progressed, wet surface snow developed on W and NW aspects as well. Ongoing supportable snow surface conditions were observed up until the conclusion of field work at 4 pm.
