The most dangerous conditions are on north and easterly-facing slope below ridgetop. You can trigger an avalanche that breaks underneath the new, wind-drifted snow and some may step down to much deeper weak layers. Evidence from the Zirkels a few days ago shows how big avalanches can be if they break on deeper layers. Avoid steep recently wind-loaded slopes. Don't let your guard down below treeline either, and heed the warning signs of shooting cracks and sounds of collapsing.
