Avalanche advisory
Sunday, March 06, 2005
Good morning, this is Drew Hardesty with the
Current Conditions:
It’s like that Far Side cartoon where the Eskimo walks out of the igloo and
reports to those back inside that ‘yup, it’s still cold’. Yup, it’s still clear and warm. With a weak system moving through to the
north and east of us, the winds picked up last night out of the northwest and
are 10-15mph along the highest ridges and should increase in speed by this
afternoon and tonight. Temperatures are
in the teens and low twenties.
Avalanche Conditions:
There were three human triggered avalanches in the backcountry yesterday and
one large natural 4-5’ deep by 130’ wide glide
avalanche (photo
2) in Broad’s Fork, a sub-drainage of BCC.
One skier in upper Coalpit Headwall kicked off a 5” deep by 10’ wide rogue
wind pocket that normally wouldn’t be problematic except for the unsettling consequences
of losing one’s footing in such an area.
Fortunately, he was not caught, which was not the luck of a skier who
took a 300’ ride in mid-Toledo
Chute in LCC. Triggering the wet
sluff at 2:30pm, she managed to avoid being buried or seriously injured. The last slide was in the
Like most things in life,
timing is everything. Wet activity
spikes by midday into the afternoon, so folks descending or recreating on the
sunny aspects should start to travel on or below lower angled terrain. On the other side of the coin, while the
probability and size of finding a rogue wind pocket is LOW, your terrain can
make the consequences EXTREME.
Bottom Line (
The avalanche danger is generally LOW, and human triggered avalanches are unlikely on
most slopes.
The avalanche danger will rise to MODERATE in the heat
of the afternoon on slopes approaching 40 degrees when they get wet and mushy.

Mountain Weather: (You can find the afternoon Weather Update here.)
Clear and sunny.
Temperatures along the ridges will be in the upper twenties with 8000’
highs just above 40. Winds will start to
increase into the 20mph range from the northwest in the afternoon. A few weak storms passing to the north this
week may bring a few clouds and a bump in wind speed, but that’s about it. The longer range models suggest a pattern
change for next weekend.
