Avalanche Conditions:
Yesterday, the moderate to
strong west and southwest ridge top winds created some localized areas of
sensitive wind drifts along the upper elevation exposed ridge lines. People were able to intentionally trigger
several of these, which were mostly about 6 inches deep and about 20 feet
wide. In the
Finally, don’t forget about
our season-long nemesis, the deeper layers of weak, faceted snow buried 2 - 5
feet deep in the snowpack. With each
incremental additional of weight of new snow, it seems to reactivate these
layers, especially on the steep, rocky slopes with a thin snowpack. All season long, we have been telling people
to wa
Bottom Line (SLC,
Today there is a CONSIDERABLE danger on
any steep slope with recent wind drifts, which means that human triggered
avalanches are likely. There is a MODERATE danger on steep
slopes without recent wind drifts, meaning that human triggered avalanches are
possible. There is also a MODERATE danger of
triggering a deeper, more dangerous, slab avalanches on slopes steeper than
about 35 degrees and above about 9,000’, especially in thin snowpack areas. If we get more than a foot of snow or if the
winds blow much stronger than expected, and as new

Mountain Weather:
Snow should diminish this
morning and we should have mostly to partly cloudy skies today with some
lingering snow showers. Ridge top winds should
blow 15-30 from the northwest with ridge top temperatures near 10 degrees. We may get another shot of snow showers this
evening and a continued chance of snow showers on Wednesday. Down at 8,000’ the high temperature today
should be around 25 with the high on Wednesday around 30. For the extended forecast, we should continue
with cloudy skies and occasional snow showers until about the weekend with
continued moderate to strong ridge top winds from the west and northwest.
