In sintesi

Areas of MODERATE danger exist on mid and upper elevation aspects facing west to north and east where it is possible to trigger a large and dangerous avalanche that may break down near the ground. Elsewhere, the danger is LOW.

There is a persistent weak layer (PWL) of old faceted snow near the ground with 3-10' of snow on top of it. This PWL exists on mid and upper elevation slopes facing west through north and east. It does not exist on south-facing slopes as any early season snow melted away and December snowfall landed on bare ground. The last avalanche into this old layering in the backcountry probably occurred on January 5th or 6th in the central Wasatch.

One party experienced a collapse in one of the Powder Parks of Mill D North of BCC on Wednesday. It's the first report of a collapse or shooting crack in quite some time. Snowpit tests continue to produce inconsistent results but we do know that weak snow exists near the ground and we do know that many experienced people continue to avoid steep terrain. For now.

Snow and Weather

Skies are partly cloudy trending clear in the wake of the cold front. Mountain temperatures have dropped into the low to mid-20s. Winds are 10-15mph from the north/northeast. The highest elevations had some gusts into the 50s and 60s with frontal passage, but are now averaging 25-30mph with gusts to 40.

For today, we'll have sunny skies, northeasterly winds at 15mph and temperatures in the high teens to mid-20s. The weekend looks the same, only warmer.

Snow surface conditions are a mixed bag of crusts with occasional patches of soft recrystallized powder in the protected terrain. Still, coverage is good and travel is easy. It should be a nice day out there.
