Good morning, this is
The Wasatch picked up 2 to 5 inches of fresh snow Thursday morning with winds moving it around quite a bit after the storm passed. Temperatures dropped into the single digits overnight at numerous mountain locations and are generally in the mid teens. Westerly winds slowed considerably overnight and the skies cleared somewhat with clouds now moving in again.
Snow and Avalanche Discussion:
The new snow combined with gusty winds drifted the snow around producing some minor natural activity along the upper lee ridges. These drifts that formed would crack under the weight of a person as well. (PHOTO) The pockets were small and didn’t run very far posing not much threat. Drew was able to sniff out a slab that collapsed and broke into faceted snow on Thursday. It was around 1.5 feet deep, 40 feet wide, and ran a few hundred feet not piling up a whole lot of debris. This weakness produced some activity a couple of weeks ago which was spotty at the time and is even more so now.
Avalanches won’t pose a great threat out there today but you will want to use normal backcountry procedures for the current conditions. Minor fresh wind slabs and warming of the new snow are the concerns for today. Slope cuts will be an affective tool for both of these issues. In the colder wind drifts you’ll get instant gratification if they are going to crack. On aspects where the snow warms, slope cuts may initiate a sluff below you. Be patient and let it run to get an idea if it is going to entrain much snow before diving in. Cloud cover may keep wet activity minimal but have it in mind.
Bottom Line for the
This morning most
areas have a LOW avalanche danger. There is a pockety MODERATE
danger in the more exposed terrain where recent drifts formed. These will mainly be on upper elevation north
through southeast facing slopes steeper then 35 degrees. The danger for wet activity may rise to MODERATE with daytime heating. You can avoid this issue by getting in and
getting out of the mountains early.
Increasing clouds this morning with scattered snow this afternoon in warm air advection is expected. Clouds are moving in this morning. Temperatures at 8000 feet will get into the mid to upper 30s and winds will be from the southwest increasing a bit as the day goes on. A cold front similar to Thursday’s disturbance should produce snow into Saturday morning with somewhat gusty westerly winds. I’m expecting only a few inches of snow this afternoon and a few more with the cold front tonight making a 3 to 6 inch event. Weather remains unsettled through Sunday bringing another chance for snow.
The Wasatch Powderbird Guides did not fly yesterday. If they can fly today, they’ll try for Mineral,
