  Triggering a persistent slab avalanche remains a possibility on wind-loaded slopes above about 9,200 feet that face NW-N-NE-E. These areas harbor weak layers (sugary facets, surface hoar, and crust + facet combinations) that remained dry during the recent hot weather. 

  Steep, rocky, wind-affected slopes with variable snowpack depths are the most suspect. Look for smooth snow pillows and dunes as indicators that the wind has been at work. You may not see obvious signs of instability, such as snowpack cracking and collapsing, before triggering a slide.

  You may be able to trigger small Wet Loose avalanches if surface crusts break down this afternoon. These are most likely during the heat of the day on very steep slopes that face the sun. Although slow-moving, these avalanches are surprisingly powerful and difficult to escape. 

  Starting and ending your day early is a great way to reduce your risk. If crusts become unsupportable, you've missed your window. Move to a shadier aspect or consider calling it a day.
