Lo esencial

Avalanche danger is LOW for all elevations. On a regional scale, triggering an avalanche is unlikely. Signs of isolated, difficult to trigger instability linger near and above treeline. Normal caution is advised.

    Isolated areas of difficult to trigger (stubborn) instability do exist near and above treeline on WNW to NW aspects within the forecast area. That said, on a regional scale triggering an avalanche is an unlikely event. Use normal caution to help improve the outcome in the unlikely event of a hard wind slab avalanche.

    In utilizing best travel practices for moving around and through avalanche terrain, make sure your partner is competent and in position to perform a companion rescue in the unlikely event of an avalanche. If you and your partner are exposed to hazard at the same time, your partner is not ready, or is out of position, you are "effectively solo", even though you technically have a partner.

    Common mistakes include:

    *Skiing/riding directly above your exposed partner even though you are technically moving one at at time. This is an easy way to create multiple burials.

    *Having a partner who is too far below to get up to a burial location in a short time (transitioning to skinning is not quick for most folks). Snowmobiles have an advantage and can get uphill quickly, but the partner must be at the ready (not helmet off with engine off).

     

     

Avalanche Discussion

* Snowpit test results targeting the isolated hard wind slabs that linger on a few WNW to NW aspects are highly variable. Isolated indications of stubborn to trigger instability remain.

* Widespread firm, wind scoured snow surfaces exist on most aspects near and above treeline.

* Variable snow surfaces with some areas of softer snow exist near and below treeline in shaded, wind protected areas.

* Areas north of Emerald Bay above 8,000', hold decent snow coverage. Below 8,000' snow coverage remains patchy and shallow.

* South of Emerald Bay, less snow exists. Areas below 8,500' hold very little snow. A deeper but highly variable snowpack exists in areas above 8,500'.

* Snow coverage continues to decrease due to melt on southerly aspects throughout the forecast area.
