Hello
and good morning, this is Toby Weed of the
Current Conditions: The
Avalanche Conditions:
A group of skiers reported intentionally
triggering a small wind slab in a gully-type terrain feature at mid-elevations
yesterday in Blind Hollow. But most
people have been wisely avoiding obviously drifted slopes in the region, and I haven’t
heard of any other recent avalanches.
There
are many places in the region where you might trigger shallow soft wind slabs
consisting of drifted new snow from yesterday, especially at upper elevations and
on steep slopes with significant deposits of drifted new snow. Strong north and west winds certainly have
been the major weather factor since the weekend, and a few hard wind slabs
probably built up on isolated steep slopes with existing buried weak layers, (weak snow photos). Yesterday’s new snow might now be obscuring
many of these potential hard slab traps, but possible clues include smooth,
chalky looking or stiffer feeling snow, hollow drum-like sounds, or shooting
cracks.
Today or tomorrow when the sun comes out
from behind the clouds, solar warming will quickly saturate the fresh surface
snow on sunny slopes causing a danger of wet point-release type avalanches.
Bottom Line: There’s a LOW danger and avalanches
are generally unlikely this morning on most lower and mid-elevation slopes and
in sheltered terrain in the backcountry. A MODERATE danger
exists and triggered wind slab avalanches are possible in exposed upper
elevation terrain on steep slopes with significant deposits of fresh or
previously wind drifted snow. Solar
warming could cause a MODERATE danger of
wet avalanches on sheltered sunny slopes with saturated snow. Use good snow assessment and safe travel
techniques to minimize your risks in the backcountry today.
Mountain
Weather: We’ll see lingering clouds, unseasonably cool temperatures, and a
few snow showers today, and then gradually warming conditions as a high pressure
builds in for the balance of the work week. A storm to the north may clip us over the
weekend, but the next real threat for significant storminess holds off until early
next week. .
The Friends of the Utah Avalanche Center in Logan is presenting an
Avalanche Fundamentals, Level 1 Class (Certification), starting March 14,
with field sessions on the 15th, and 22nd. Please register in advance with the Friends
via e-mail or for more information contact [email protected].

this season’s avalanches.

the Avalanche Encyclopedia if you have any questions about terms I use in the advisory.
I'm very interested to
know what you're seeing out there. Please e-mail observations to me
at [email protected] or leave me a message at 755-3638, especially if you see or
trigger an avalanche in the backcountry. We keep all observations confidential.
This advisory will
