Quick report
- Cracking
- isolated
Tam (and most of the central Cascades) got an upside-down storm system with approx. 5 feet of snow over the week turning to rain Thursday night at all but the highest summit elevations. This rain immediately froze, becoming a rain crust that got buried by approx. 20cm of light, dry pow. We didn't find propagation on the facets below this rain crust in several hasty pits, but the crust was breakable and influenced our terrain decisions to stick to lower-angle ski lines. Several parties ventured into steeper terrain and caused minor slides in the upper snowpack. Let's keep an eye on the facets below the rain crust as we get more snow in the coming days!

Upper-snowpack (top 20cm) inconsequential slides that could have had worse outcomes if they ripped deeper and carried either skier through the trees in the runout zones below.
