Highlights

Strong winds will continue to rake the snow surface at mid and upper elevations.  While it will be easy to find wind-affected snow,  it's unlikely you'll trigger a wind slab avalanche.  At lower elevations,  steer around steep slopes where you find wet and weak snow.  

Avalanche Discussion

It will be another day with strong E-NE ridgeline winds buffeting the East South and raking snow surfaces.  For terrain exposed to the wind,  it will feel cooler than the freezing level and full sun in mid-April would otherwise indicate.  Lower elevations and terrain sheltered from the wind will warm several degrees from Tuesday through Wednesday. 

Wind slabs that formed over the weekend have likely become unreactive.  E-NE winds may have cross-loaded slopes over the last 24 hours, but with minimal snow to transport, new wind slabs are also unlikely.  Continue to use care when approaching steep rocky terrain with wind loaded snow,  this may be the last best spot to trigger a wind slab avalanche.  

At lower elevations and wind-sheltered sunny slopes, surface refreezes will break down quickly as the day heats up.   Where you find yourself sinking into wet snow deeper than your ankle or if you see signs of increasing instability like rollerballs or natural wet loose avalanches, move to shadier or lower angle terrain.  Don't get caught in a wet loose avalanche above terrain traps like cliff bands or open creeks.  Firm slopes you traveled on or below during the morning hours may be ripe for wet snow avalanches or cornice fall in the afternoon. 

Cornices are large and will fall down during the spring.  Give them space along ridgelines and don't hang out on slopes below large overhanging cornices. Be prepared for spring travel hazards like exposed creeks, trees and rocks as southerly slopes and lower elevations continue to melt out.
