Good morning, this is Brett Kobernik with the
Ridgetop winds picked up from the south Thursday afternoon blowing in the 20 mph range with gusts into the 30s. They appear to be slowing somewhat now with ridgetop temperatures in the low 20s. Under mostly cloudy skies, snow showers are occurring in the mountains with accumulations of 1 to 2 inches. The snow surface is a mix of settled powder, sun crusts, wind crusts and wind drifts depending on elevation and aspect.
Recent Avalanche Activity & Snowpack Discussion:
No new avalanche activity was reported from Thursday so let’s take a look back at the significant weather events that shaped this week’s snowpack. Last weekend we received a shot of light density snow that then got whipped into drifts on Tuesday from a period of strong southerly winds. This produced a small natural avalanche cycle. Wednesday the mountains received another shot of snow especially the Cottonwoods where 14 to 20 inches of snow fell in a very short period of time which produced another natural avalanche cycle. By Thursday, the new snow had settled and the wind drifts from Tuesday were staying in place. Temperatures warmed Thursday making the lower elevation snow become damp but left the upper elevations with cold loose snow that was starting to drift as the winds picked up in the afternoon which brings us up to now.
For today we will want to watch for any fresh drifts that formed late Thursday and last night. You will mainly find these along the upper elevation ridgelines on northerly facing slopes. Today we will also want to watch for damp and wet activity at the lower elevations. Avoid steep lower elevation slopes and terrain traps as the snow becomes moist throughout the day. Cloud cover today should keep a lid on solar heating on high elevation southerly facing slopes but if it does break you will need to watch for activity here as well.
This morning most areas have a LOW avalanche danger.
However, the avalanche danger is MODERATE on upper elevation northwest through northeast facing slopes
steeper than 35 degrees with recent deposits of wind drifted snow. The danger will also increase to MODERATE at lower elevations as the snow becomes damp from daytime
heating. You will need to watch high
elevation southerly slopes if we see some clearing this afternoon as well.
