Highlights

Triggering an avalanche up to 1-2 feet thick is possible in wind-loaded terrain at all elevations. Recent snow and wind continue to stress weak layers buried 3-5 feet deep, increasing the chances of triggering a very large avalanche. Evaluate steep terrain carefully, and use extra caution near steep wind-loaded features.

    New snow and strong west/southwest winds have formed fresh wind slabs up to 1 foot deep at all elevations. These slabs will continue to grow as winds continue to transport snow today. Slabs could be sensitive to the weight of a rider in very steep terrain. While becoming less likely, older wind slabs with depths up to 2 feet could be triggered in heavily loaded areas along ridgelines and near the base of cliffs. Fresh wind slabs also have the potential to step down to buried weak layers, creating a larger, more dangerous avalanche. Pillows, fresh cornices, and stiffened surfaces are all indicators that winds have recently loaded slopes. Stay alert for signs of instability such as recent avalanches and shooting cracks near exposed ridgelines, and cross-loaded terrain features. If these signs are present, move to lower-angle slopes. Giving very steep and wind-loaded features a wide margin is the best way to manage this problem today.

    Weak layers of sugary facets exist in the middle of the snowpack and near the ground on most slopes. Avalanches involving these layers will be 2-3 feet deep, and up to 5 feet deep on heavily wind-affected slopes. Triggering one of these dangerous avalanches is possible on very steep slopes over 35 degrees. Signs of instability such as cracking, collapsing, or recent avalanches may not be present before triggering a large avalanche capable of propagating long distances. Multiple tracks on a slope do not indicate stability with this problem type. Suspect terrain includes very steep, rocky, and/or wind-affected slopes where thin spots exist, making it possible for humans to impact buried weak layers.

    Recent snow and wind are stressing these buried weak layers and increasing the likelihood of triggering a persistent slab avalanche. Wind slabs triggered on the surface could step down to deeper weak layers resulting in a larger avalanche than expected.

    The last human triggered persistent slab avalanche occurred on March 2nd in terrain similar to this.
