Loose avalanches can run on any steep slope receiving direct sun.  You are most likely to trigger a recently formed wind slab below ridgelines or near steep rocky terrain.

Observers in the Hurricane Ridge area on Sunday noted loose, dry snow on northerly aspects and variable conditions with a mix of surface crusts on other aspects in the Hurricane Ridge area.  No new avalanches were reported.  On Saturday, NPS rangers reported whumpfing and shooting cracks on a low angle North aspect near treeline.  The interface was likely the 3/18 pre-storm layer.  S-SW winds have drifted recent storm snow onto W-N-E aspects.  About 2' of snow accumulated in the Hurricane Ridge area over the weekend. 

The Hurricane Ridge area went in and out of clouds and showers on Monday, with enough sunbreaks that a few small wet loose avalanches likely occurred on steep southerly slopes.  Think about wet loose avalanches again if the sun comes out Tuesday.  Watch for rollerballs or pinwheels that release naturally on very steep sunny slopes or below rock faces, or if you find yourself sinking into wet surface snow more than ankle deep, it's time to change aspect or move to lower angle terrain.  There's a chance that high clouds could dampen the sun's impact, so keep an eye on how sky conditions change throughout the day.   Loose dry avalanches are possible on very steep slopes in northerly or shaded terrain.  Don't let either type of loose avalanche catch you by surprise around terrain traps.   

Recently formed wind slabs are likely to be found at upper elevations and on the lee side of ridgelines and below cliffs bands where spindrifts have deposited recent snowfall.  As you travel, feel for textured wind-affected snow as you change aspect and elevation.   Wind slabs may be easier to trigger on northerly aspects where they built over weaker, older snow.  If traveling along ridgelines with large cornices make sure to stay well back from the edge.  Travelers are surprised every season when cornices break further back than they expect.  Cornice fall could trigger an avalanche on the slope below.

During the ongoing Covid-19 pandemic, continue to follow the latest guidance from local, state, and federal health officials. Avoid unnecessary risks that could impact first responders and stress medical resources.  Wear a mask when appropriate, practice social distancing, and consider recreating closer to home.
