Above-freezing temperatures Monday night extend to 11,000 feet in elevation and will create heightened risk of natural and human-triggered wet avalanches on most slopes Tuesday, particularly at lower elevations. A poor freeze means that even an early start may not be enough to keep you off of wet, unsupportable snow, but you can expect the hazard to ramp up first at lower elevations, following the sun from east to south to west and extending into higher elevations as the day progresses. Roller balls and wet, cohesionless surfaces are signs of unstable snow. Plan ahead and make an exit if you see these danger signs on any slope, or if you start sinking past your ankles.
Steep upper-elevation northerly and east-facing slopes still harbor cold snow where you may be able to trigger an avalanche on slopes where stiff, wind-drifted slabs sit above weaker layers below. Avoid traveling beneath large cornices, as the warm temperatures will increase the risk of dangerous cornice falls or cornice-triggered avalanches on the slopes below. Smooth, supportable slopes without rocks or vegetation and with no steep terrain overhead provide safer choices.
