Heading out with the mind set of "LOW means GO" may lead you into terrain where triggering a small avalanche has severe consequence, and these are still possible in extreme terrain. Check the alpine weather stations for inverted temperatures. 

Weather Forecast

Nice weather for the weekend. Inverted temperatures Saturday and Sunday with valley bottoms down to -25C and alpine temperatures at 3000m as high as -6C. Winds will be light and switch from E flow into a SW flow in the evening. No snow is expected until Monday when winds will increase with light snow along the divide.

Snowpack Summary

Cold temps continue to facet the entire snowpack. There is widespread but mainly unreactive wind effect in the alpine. The Nov 8 crust is down 20-30cm up to ~2400m which is facetting over time. The lower snowpack is a mix of weak facets & crusts. Snowpack depths at treeline vary from 60-90 cm with up to 140 cm in lee areas.

Avalanche Summary

No new avalanches observed Friday.

Confidence
