Travel and Terrain Advice
Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Closely monitor how the new snow is bonding to the crust.
Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet
Pay attention to cornices and give them a wide berth when traveling on or below ridges.
