Good Morning. This is Ethan Greene with the
Last night under mostly clear skies temperatures dipped to near 30 degrees at 8,000 and into the mid 20s at 10,000. In most areas the winds have been blowing in the 10 mph range from the west, but along the highest ridges they increased into the 25 mph range this morning.
The snow surface is a mix of soft surface facets and thin sun crusts. The crusts are most prevalent on south and east aspects, and the snowpack is generally supportable above about 8,000.
Yesterday I received several observations of people getting into steeper terrain and traveling without incident. These observations were juxtaposed with reports of localized cracking and collapsing of the snowpack and moderate scores from stability tests. This combination indicates that the current weather pattern is causing the snowpack stability to increase, but since we started off with such a weak pack it is taking its own sweet time.
Today you may find areas of fairly stable snow and fairly weak snow existing within close proximity. This means that even though you just crossed a steep slope there may be a booby trap waiting around the corner. As the spatial variability in our snowpack increases use your best avalanche route finding skills to stay safe. Evaluate the stability of each slope before you cross it, and remember to travel one at a time between islands of safety.
Bottom Line (SLC,
Today there is a MODERATE danger of triggering a deep slab avalanche on slopes facing northwest, north, northeast and east, above about 8,500 that are steeper than 35 degrees. Steep slopes with recent wind deposits also have a MODERATE avalanche danger. On south facing slopes the avalanche danger is generally LOW.
There is a ridge of high
