Good morning, this is Drew
Hardesty with the
Current Conditions:
Under partly cloudy skies
last night, mountain temperatures dropped into the low teens, while winds
remained generally light and out of the west.
Yesterday’s snow showers added up to about 4-5” in some locations, and
it looks like most places across the range received at least a couple of
inches. Today looks to be partly cloudy
with light west and southwesterly winds.
8000’ highs today are expected to reach past 40 degrees. Snow surface conditions range from punchy,
inverted powder, to areas with zipper crust to sloppy down low.
Avalanche Conditions:
Avalanche activity yesterday
was confined to both natural and human triggered loose snow avalanches on steep
slopes on all aspects. Some of these were
reportedly running pretty far, where they could easily carry a person over cliffbands or into trees.
My major concern today, however, will be avalanches from daytime heating
and, under partly cloudy skies, direct shortwave radiation. As the snow from the last two days is still “upside
down”, it may not take a lot of warmth and heating for them to become
reactive. Rocky outcrops, cliffbands, and trees also tend to channel heat well – take
time today to be aware of how the snow is reacting to today’s weather. Wet activity may be a problem on the sunny
aspects and at the mid and lower elevations on the shady side. Once the snow starts to get wet and mushy, it
might be time to get off of and out from underneath steep slopes.
Bottom Line:
The avalanche danger is MODERATE
on slopes steeper than about 35 degrees.
As temperatures reach their daytime highs, the danger may rise to CONSIDERABLE.
There remains a MODERATE danger of
triggering a deep, dangerous hard slab avalanche in steep terrain, especially
in thinner snowpack areas.

Mountain Weather:
We’ll
have partly cloudy skies and warmer temperatures today, with 8000’ highs
reaching just over 40 degrees. 10,000’
temperatures will be in the low 20’s.
Winds will remain light and westerly. Temperatures should gradually increase during
the week with high pressure the main feature for the weekend and next
week. Looks like we’ll
be skiing and riding corn before long.
