, the treeline rating is , and the below treeline rating is Known problems includeA storm Thursday night into Friday will likely increase the wind slab problem at upper elevations. Watch locally for snow amounts and how the wind is transporting it. Ridge tops and gully terrain will be likely areas to find new wind slabs. SH
Summary
Weather Forecast
A vigorous low is approaching the divide. 24 hour snow quantities should see 10-25cm. This will be accompanied by a cold front. Expect moderate to strong SW winds at upper elevations, easing in the afternoon.
Snowpack Summary
15-30 cm of snow sits on top of a supportive (5-10cm) crust except on high N which overlies a strong base. The bond to the crust seems strong in most places. Winds over the day have changed the surface in many areas and new wind slabs are starting to form in alpine lee areas.
Avalanche Summary
A few size 1-1.5 avalanches were noted in the quartz ridge area of the Sunshine back country, otherwise no new were reported.

- Be careful with wind loaded pockets while approaching and climbing ice routes.
- Use caution in lee areas. Recent wind loading have created wind slabs.
