Lo esencial

LOW avalanche danger exists for all elevations. Isolated loose wet avalanches may occur today.

    Loose wet avalanche activity is unlikely today in most areas, but there are issues to keep an eye out for that could lead to isolated instability. Conditions were not ideal for snow surface refreeze last night with above freezing air temperatures and some cloud cover. The snow surface in heavily treed areas may have a refreeze that is weak to nonexistent. Open slopes may have a weak to moderate strength superficial refreeze. Increasing cloud cover today is expected to limit snow surface warming from solar radiation, but light rain on snow below 8,500' will provide a small amount of melt and free water. Use caution if encountering surface wet snow in avalanche terrain. Steep NW-N-NE aspects that receive rain on lingering unconsolidated recent storm snow may be where the most problematic instability occurs today.

    Move to low angle terrain if encountering roller balls, pinwheels, or unsupportable wet snow.

Avalanche Discussion

* Unconsolidated recent storm snow, yet to be affected by melt lingers on steeper N aspects at the mid and upper elevations.

* Breakable to supportable melt-freeze crust exists on the snow surface in sun exposed areas, including on low angle northerly aspects.

* The deeper snowpack remains well bonded with instabilities occurring relatively close to the snow surface.

* No new avalanche activity was reported during the last 24 hours.

Forecast new snow amounts today above 8,500' are insufficient to create new problematic wind slabs. If forecast snowfall amounts are exceeded today, consider the presence of this problem in lee areas along ridgelines and below cornice features. This avalanche problem may form by sunrise tomorrow.
