current conditions The Tony Grove Snotel at 8400' reports 22 degrees this morning and 14 inches of new snow in the last 24 hrs, containing 1.1" of snow water equivalent. There's an even 100 inches of total snow containing 106% of average water for the date. I'm reading 14 degrees at the 9700' CSI Logan Peak weather station, with steady north-northwest winds, now averaging around 18 mph. Drifting of significant overnight accumulations by sustained northwest winds probably created dangerous wind slab avalanche conditions on some upper elevation slopes.

description
Heightened wind slab and cornice fall conditions exist due to significant overnight accumulations and drifting at upper and mid elevations, with avalanches possible on many slopes. There are probably some more dangerous drifted slopes at upper elevations where human triggered avalanches are likely.
A beautiful photo by Jeremy Jensen (the Mayor of Tony Grove) from Saturday morning showing a recent natural avalanche in Castle Rock near Naomi Peak. The large wind slab (or perhaps persistent slab) looks like it was triggered by cornice fall. (3-19-16)

If the high angled March sun comes out for a while later today, loose wet avalanches entraining a good amount of fresh snow will become possible, especially in sheltered sunny terrain. |
weather Expect partly sunny conditions in the mountains today, with 8500' high temperatures around 31 degrees and continuing northwest winds. There's a chance for a few snow showers this afternoon, but little accumulation is expected. It'll be mostly cloudy tonight with a low temperature around 21 degrees and west-northwest wind. It'll be mostly cloudy tomorrow, with high temperatures in the mid thirties, westerly winds around 20 mph and show showers in the afternoon. The next Pacific storm system will arrive late Friday and affect the region through Saturday. |
