High pressure is in command this morning, and under clear skies temperatures have warmed to near 20 degrees at many ridgeline locations. Winds are steadily decreasing, and generally less than 15 mph from a northwesterly direction. Turning and riding conditions are very good on all aspects this morning in creamy powder, with easy trail breaking. As the day progresses, the sun and warm temperatures will dampen the snow on the steep sunny slopes.
Explosive control work yesterday pulled out yet another big one on the
It is also still possible to trigger a shallower, new snow slide, especially in wind drifted areas. An intentional cornice drop in Alexander yesterday triggered a 100’ wide by 18” deep slide. There is the scary potential for the weight of one of these smaller new snow slides to step down and trigger a deeper slide.
I also expect some wet snow activity today on steep sunny slopes due to the rapidly warming temperatures and direct sun. As the snow heats up, stay off of and out from under steep sunny slopes, especially avoiding terrain traps such as gullies.
The avalanche danger is MODERATE today on
slopes steeper than 35 degrees, above about 9,000’. There are isolated places where a person
could trigger a deep, dangerous slide, on west through north through east
facing slopes. Avoid traditionally
shallow snow pack areas, especially those that were heavily wind loaded during
the last storm. The avalanche danger
will rise to MODERATE on steep sunny slopes with day
time heating. The danger is generally LOW below about 9,000’ (8,500’ in the
High pressure will dominate the weather through Friday. This will bring clear skies and a strong
warming trend today, with 10,000’ temperatures climbing into the mid 30’s, and
8,000’ temperatures into the mid 40’s.
The northwesterly winds will remain generally less than 15 mph. It will be a copy cat day tomorrow, but with
temperatures another 5 degrees warmer.
The ridge will give way for the weekend, with the best chance for snow
Sunday into Sunday night.
