Forecast rain to mountaintops may trigger wet loose avalanches on all aspects.

On Friday, numerous naturally triggered wet loose avalanches up to size 1.5 were reported.

NOTE: Observations are currently very limited in this region.

Forecast 5 to 15 mm of rain to mountain tops on Sunday will create wet snow surfaces.

An old persistent weak layer may still be present 100 to 150 cm below the surface on high north-facing slopes.

Treeline elevations still hold over 200 cm of snow, but coverage is rapidly thinning at lower elevations.

• A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
• Back off slopes as the surface becomes moist or wet with rising temperatures.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
