Hello and good morning, this is Toby
Weed of the
Current Conditions:
I had my
hopes up for a big dump, but it looks like we got gypped again….Tony Grove
Snotel picked up around 6 inches of new snow in the last 24 hrs containing a
little more than a half inch of water, which is on par with other sites across the
region. The National
Weather Service still has the
Avalanche
Conditions:
No
significant avalanches have been observed or reported in the region
recently.
Moderate
northwesterly winds accompanying periods of heavy snowfall today will be strong
enough to build drifts in lee slope starting zones and around wind breaks and
terrain features. Fresh wind slab
avalanches up to a foot or so deep are possible on drifted slopes steeper than
about 35 degrees, and the danger of will be on the rise today. Strong winds are possible in exposed
upper elevation terrain, and with periods of heavy snow likely during the day,
drifting will be more widespread and potential wind slabs more significant. As usual you should avoid any fresh or
building drifts on steep slopes.
Loose
dry snow avalanches or sluffs are possible on steep slopes in more sheltered
terrain. Not much of a
problem with less than a foot of new snow, but could cause problems in gullies
or other abrupt terrain traps. As
soon as the seasonally high angled sun comes out for any length of time, (most
likely on Thursday), the surface snow will quickly become saturated and
significant loose wet avalanches consisting of the new snow will become likely
on steep sunny slopes.
Bottom Line:
There’s a MODERATE danger in the backcountry, and human
triggered wind slab and loose snow avalanches are possible on slopes steeper
than about 35 degrees. You are most
likely to trigger wind slabs at upper elevations near ridge lines and on slopes
facing northeast through south, but any steep drifted slope is suspect. You’ll
want to assess snow conditions while following safe backcountry travel protocols
to minimize your risk.
Mountain
Weather:
Wrap-around
from the slow moving storm will hopefully bring periods of heavy snowfall to the
region under a northwesterly flow throughout the day on Wednesday. 4 to 8 additional inches are
possible. Expect clearing
conditions and gradually rising temperatures on Thursday, and a gradual warm-up
as a high pressure system rebuilds over the region for the weekend.
