In sintesi

The avalanche danger is generally LOW this morning. As the day heats up the danger for loose wet and wet slab avalanches could rise to MODERATE by afternoon. Signs of instability include rollerballs, pinwheels, and punchy or sloppy unsupportable snow. Work slopes according to their aspect and get off of and out from under steep slopes as they become wet and sloppy. With water moving through the snowpack, slopes do not have to be in the sun to be dangerous. Thin shallow rocky areas and terrain under cliffs should be avoided.

    Loose Wet Avalanches:

    Be on the lookout for loose wet avalanches as the day heats up. Signs of instability include rollerballs, pinwheels, and "point release" sluffs that fan out and gather more snow as they travel down the slope. Timing is everything this time of year. Work slopes according to their aspect in relation to the sun and get off of steep slopes as they become wet and sloppy.

    Wet Slabs:

    Record temps and light to no overnight re-freezes a few days ago produced wet slab avalanches. This type of wet snow avalanche is harder to predict than loose wet it but can be invariably more dangerous. Wet slabs release when melt water saturates a layer in the snowpack and the over riding slab fails as a cohesive layer. Outward signs of this type of problem are not obvious but sloppy, wet, or punchy snow indicates that the pack is trending towards unstable. With water moving through the snowpack, slopes do not have to be in the sun to be dangerous. Thin shallow rocky areas and terrain under cliffs should be avoided.

Kevin Dressel spotted this wet slab avalanche from his back porch. This is a large avalanche failing to the ground.

Snowpack Discussion

Several nights with a solid refreeze and overall cool temps yesterday have helped to lock up the snowpack and we're moving into what looks to be an extended corn cycle. This morning we'll see a solid, supportable crust that will gradually soften with the sun. The problem is finding a south aspect that hasn't melted out. Work the aspects starting with SE around 10:00 and end up on W around noon. North aspects remain in transition. Once the crust becomes unsupportable and the snow starts to get sloppy, it's time to call it a day as the danger for loose wet, or even wet slab avalanches will start to develop.
