The avalanche danger is MODERATE. Heightened conditions exist on drifted slopes at upper and mid-elevations. People could trigger avalanches of wind-drifted storm snow up to 2 feet deep on slopes steeper than 30 degrees. When the strong April sun comes out from behind the clouds, it will elevate the danger of loose wet avalanches entraining fresh snow, with natural and triggered wet avalanches possible on steep slopes.
Human-triggered avalanches of stiffer wind-drifted storm snow are possible on steep slopes near ridgelines and in and around terrain features like cliff bands, gully walls, and sub-ridges.
Shallow wet avalanches entraining the new snow are possible on steep sunny slopes if the sun pokes out even for a short period.
Pay attention to potential terrain traps below you, like trees, cliffs, or gullies, that a small avalanche might carry you into.
We observed numerous natural loose avalanches of new snow yesterday in the Tony Grove Area. Despite ongoing drifting, we did not see any wind slab avalanches, and we stayed away from drifted slopes.

Natural loose dry avalanches, or sluffs, were widespread on steep slopes in the Tony Grove Area on Tuesday.
Yesterday, we found excellent cold and (shallow) powder riding and skiing conditions in the Tony Grove Area. There was plenty of graupel, and heavy snowfall and drifting quickly filled in our tracks... We found the best conditions on lower-angled slopes with smooth underlying snow. We observed numerous small natural loose avalanches of storm snow, no wind slabs despite ongoing drifting, and increasing stability during the day.
Yesterday's storm elevated avalanche conditions in the backcountry, with human-triggered avalanches of wind-drifted storm snow possible on steep slopes at upper and some at mid-elevations today. Partly sunny skies are expected, and periods of high-angled April sun will rapidly elevate the danger of shallow wet loose avalanches on sunny slopes. Heightened wet avalanche conditions are likely to develop, with some natural activity likely.
Most low-elevation terrain below about 7000 feet in the Logan Zone is completely melted off or has very shallow, spotty coverage.
The Tony Grove Snotel at 8400 feet reported around 3 inches of new snow overnight and 7 inches in the last 24 hours with .7" SWE. It's 16° F, with 101 inches of total snow. About 4 inches accumulated at the Card Canyon weather station at 8800 feet. It's 14° F and there is 76 inches of total snow.
At 9700 feet at CSI's Logan Peak Wx station, winds are blowing from the northwest 14 to 27 mph, and it's 12° F. The winds on Paris Peak at 9500 feet are blowing from the west 11 to 20 mph, and it's 11° F.
It is partly cloudy this morning at Beaver Mountain, and there is about 3" of new snow on their snowstake. (Check the Beaver Mt Webcams) Snow showers are likely this afternoon, but little accumulation is expected. Expect a high temperature at 9000 feet around 29° F, and a west wind will blow 5 to 10 mph. Partly cloudy skies are expected tonight, with a low temperature around 16° F. Winds will blow from the west-northwest wind 5 to 9 mph becoming north after midnight. Tomorrow there is a 40 percent chance of snow showers after noon, with new snow accumulation of 1 to 2 inches possible. It will be partly sunny, with a high near 33° F. Winds will blow from the north-northeast 6 to 10 mph becoming west in the afternoon.
Unsettled weather will continue through the work week, with very nice, sunny, and fair weather expected for the coming weekend.

We found nice powder conditions and improving snow stability yesterday, and clouds and cold mountain temperatures preserved the snow quality for today.
