The Bottom Line: Light snow and wind will drive heightened avalanche danger at the highest slopes. Watch for fresh drifts, wind stiffened snow, and slippery old snow surfaces. Rain will fall at low elevations.
Snow and Avalanche Discussion
A variety of old snow surface exist from weak facets on shaded slopes to very firm, slick crusts on sunny slopes. New snow may not stick well to some of these interfaces. Check the bond at the new/old snow interface. Watch for slipping on firm crusts especially in terrain where a fall could have consequences or where stopping a fall may be difficult.
Check out the Regional Synopsis tab for more details.
