Great ski conditions exist right now. Watch for sluffing out of steep terrain with any sun or wind inputs and be sure to manage your sluff if you're in steeper terrain.
Summary
Weather Forecast
Light snow in the forecast with 5-10cm by Tuesday with continued light SW winds. Temperatures are forecast to remain cool (-5 to -15C) depending on elevation and slowly warming through the week. Overall, fairly benign weather with no significant inputs forecast over the next few days.
Snowpack Summary
10-20 cm of storm snow with little wind effect sits over buried wind slabs in open areas at higher elevations, and over loose facets at lower elevations. Below this a firm mid-pack covers the Jan surface hoar layers that are rounding and inactive in tests. The deeper facet layers down 80-150 cm found in shallow areas remain weak.
Avalanche Summary
Small loose snow avalanches/sluffing has been reported in some steep treeline areas with the storm snow failing on the facets below and running a fair distance. The persistent weak layers have been inactive for two weeks and have been removed as a problem.
Confidence
Problems
Loose Dry
10-20 cm of storm snow has fallen with little wind. In many places this sits over loose facets from the last cold snap and with any increase in wind, sun or skier triggering, we will see small sluffs traveling a long ways in steep terrain.
On steep slopes, pull over periodically or cut into a new line to manage sluffing.The volume of sluffing could knock you over; choose your climb carefully and belay when exposed.
Aspects: All aspects.
