Highlights

A MODERATE danger exists for triggering a 1-2 foot thick slab avalanche in steep northwest to easterly facing terrain of the mid and upper elevations. Heightened avalanche conditions exist on specific terrain features.

Pay attention to the warming temperatures as WET LOOSE AVALANCHES will become possible on steep solar terrain.

It's been a dry early season and this naturally leads to a thin, weak snowpack and an overall poor structure. In wind loaded areas, it may be possible to trigger a soft or hard slab avalanche that fails on this early season weak faceted snow. This weak faceted snow is known as a PWL (persistent weak layer) for a reason - that it takes a very long time to heal. These avalanches may be 12-18 inches deep and up to 100 feet wide and most likely found in the mid and upper elevations.

Look for pockets of hard and soft wind slab around terrain features of the mid and upper elevations. While stubborn, these can crack out on you, even while you may be out on the teardrop of the plate of cohesive snow.
