current conditions The Tony Grove Snotel at 8400' reports 17 degrees and nearing a couple feet of new snow, with continuing snowfall, 2.4" of water in the last 48 hrs and 1.9" in the last 24! There's 86 inches of total snow containing 98% of average water for the date. I'm reading 10 degrees at the 9700' CSI Logan Peak weather station, but the wind sensor appears to be encased in rime. Mt Ogden shows a decrease in wind speeds since yesterday morning's crazy weather, but I'm still reading sustained westerlies averaging around 25 mph. The National Weather Service in Salt Lake City has continued a Winter Weather Advisory for the mountains of Northern Utah, (north of I-80) with continued snow showers, a few more inches of accumulation, and drifting from intensifying westerly winds expected in the mountains. Beaver Mt expects very good powder conditions today, with snow all day yesterday refilling tracks, and a few more inches overnight.

recent activity
On Saturday (3-12-16) around noon, I saw a recent loose wet avalanche and stopped to gather the riders in our level 1 class. As several of us waited for the rest to join we watched as a second wet avalanche occurred right next to the first one. ***To view our updated list of backcountry observations and avalanche activity from around Utah, go to our observations page

description
Dangerous wind slab avalanche and cornice fall conditions probably exist in drifted upper and mid elevation terrain. Strong southwest and west wind, sometimes during periods of heavy snowfall yesterday moderated a bit but continued overnight. The wind picked up the fresh snow in upper elevation fetch areas and drifted it into lee slope avalanche starting zones. We expect drifting will continue with increasing west wind today.

In some areas the new snow may not bond very well with last week's warm snow surface and 1 to 2-foot-deep soft slab avalanches involving the new snow are possible in some steep terrain.

If it stays cold and cloudy, there will be no loose wet avalanche problem. But, if the sun pops out for a bit and moistens the fresh snow, loose wet avalanches entraining the sticky fresh snow will become likely and could be fairly large. |
