Kernpunkte

Avalanche danger remains LOW for all elevations and aspects. Some small loose wet snow instabilities could still occur on some steep slopes today on any aspect. Continue to use normal caution when traveling in the backcountry.

    Sunshine and warm temperatures will allow wet snow to form on the surface again today. Some roller balls and pinwheels may occur on steep slopes where wet surface snow forms. These could happen on any aspect today and may become more prevalent on the northerly aspects since cloud cover could allow those aspects to warm up this afternoon. These instabilities should not involve enough snow to bury a person, but they could push someone off course or knock a person over. Isolated small loose wet avalanches are not outside the realm of possibility today on all aspects on slopes 37 degrees and steeper.

Avalanche Discussion

Yesterday observations on Chickadee Ridge showed soft unconsolidated snow on the north aspects, sun crusts on the E-ENE aspects, and transitional melt-freeze snow that has not "corned-up" on the southerly aspects. Snowpit tests, ski cuts, and general observations did not reveal any signs of instabilities. Snow melt on the southerly aspects had exposed many areas of bare ground in this area. SE-S-SW aspects across Mt. Rose Hwy. including Rose Knob Peak and the main snowmobile access area also have melted back to bare ground in many places. This exposed ground has impacted snowmobile access.

These observations correlate well to other recent observations from around the forecast area. Soft cold snow still exits on north aspects above 7800 ft. and coverage on these aspects remains decent. Southerly aspects including those in the Carson Pass, Mt. Rose, and Castle Peak areas have melted out significantly and only hold patches of snow in most places. The snow that remains on those southerly slopes has not transitioned to corn in most places and still becomes wet and sticky when it warms up. Easterly aspects hold sun crusts and transitional melt-freeze snow.
