The warmest weather the forecast area has experienced in months has arrived. After a poor overnight re-freeze and expected daytime temperatures in the 50s, snow surfaces near and below treeline will continue to weaken. Surfaces will be most unstable during the heat of the day. This problem is specific to steep, sunny slopes holding wet, penetrable snow. While not life- or limb-threatening, it could have consequences in steep, concave terrain where snow can funnel and build up. Recognize and identify terrain traps. Pinwheels and roller balls will be the first signs of rising instability. Sinking into damp snow that exceeds your boot cuff means it's time to move off steep slopes and seek shadier terrain.
