bottom line We are no longer issuing danger ratings, but heightened avalanche conditions exist in the backcountry and will continue through the weekend. Watch for and avoid fresh wind slabs and sensitive cornices in drifted upper elevation terrain. Loose wet avalanches entraining saturated new snow will become likely in steep terrain with inevitable seasonal warming. Avoid steep sided gullies, trees below steep slopes, and other potential terrain traps. Evaluate the snow and terrain carefully.

current conditions It's 31 degrees this morning up at the 8400' Tony Grove Lake Snotel, and there's about 6 inches of new snow from overnight, with 84 inches of total snow containing 128% of average water for the date. It's 28 degrees at the 9700' CSI Logan Peak weather station, with south-southeast winds averaging around 25 mph.

recent activity There have not been any new large avalanches reported in the Logan Zone since the very warm and active spell earlier in April, but I triggered a few moist sluffs entraining fresh snow in Providence Canyon on Wednesday and we noticed a few natural loose wet avalanches up high in the Wellsvilles on Thursday.
A few natural avalanches visible up high in Bird Canyon above Mendon. 4-24-2014 Visit our Backcountry Observations Page for details on the season's activity.

As the fresh snow warms, it'll get moist and more cohesive, and loose wet avalanches entraining the fresh snow will become likely in steep terrain. Avoid steep sided gullies or avalanche paths and steep slopes above trees, and be aware of other potential terrain traps. |

description
Southeast winds overnight and this morning continued to form shallow wind slabs and build out cornices at upper elevations. You could trigger wind slabs at upper elevations in steep drifted terrain, and you should continue to avoid and stay out from under cornices, which might break further back than you expect and could trigger avalanches on slopes below. Continuing snowfall and winds today will cause an increasing danger and heightened conditions will continue through the weekend.
