Primary Problem: Wet Snow
Bottom Line: Warm temperatures, wind-loading, and the possibility of rain and snow later in the week will drive avalanche problems. Wet snow avalanches will be the primary concern on most slopes. Get on to the snow early in the day when surface-level crusts are supportable and get off when the crust breaks down and more than the upper few inches of snow become slushy and wet. Relatively small wind-slab avalanches are possible on upper-elevation slopes that remain shady and cool. If the upper snowpack is dry, dig down and back off steep objectives if you find instability in your tests, observe shooting cracks or indications of fresh wind-loading. Reevaluate conditions when a mix of rain and snow moves into the area on Thursday and Friday.

From IG mesasge (4/6): "Some wet action at arange peak near Sawtell yesterday. From slope Dave and I did our first pit on Monday. Lots of release in that new old interface but didn’t see anything releasing down deeper."

  • Went to do maintenance on the Sawtelle Snowfall weather station at 8800 ft just off the Sawtelle Mountain Road. Continuous snowcover starts around 8000 ft. At 8800 ft there is ~20" of snow with a mix of hard crusts and weak facets. These weak layers near the ground will be something to watch once snows again. Photo: GNFAC
