Kernpunkte

The avalanche danger will rise as the day warms and unstable conditions develop on steep slopes facing the sun. Natural and human-triggered wet snow avalanches will become likely later in the day. Deeper avalanches involving weak layers of snow buried 3-5 feet deep are still possible in very steep terrain. Conservative terrain selection and avoiding very steep, sunny slopes is recommended today.

Several bear sightings have been reported this spring. When planning for the day, bear spray, group travel, and appropriate food storage should be considered.

    Above-average temperatures for the third day in a row and a lack of overnight freezing will make natural and human-triggered wet avalanches likely on steep slopes that face the sun today. The majority of these avalanches will be on the smaller side however it’s possible that some could entrain enough snow to injure or bury you. These avalanches are most likely to begin around rocks or trees and can entrain large amounts of snow as they move downhill. Temperatures climbed to the high 50s F on the pass yesterday and did not drop below freezing overnight. Any surface crusts will break down quickly as the day warms, leading to unstable conditions on sunny slopes. Look for signs of warming, such as natural wet avalanches or slushy unconsolidated snow. Consider moving to shaded, low-angle terrain if these signs are present. Minimize time spent under large, sunny slopes.

    Cornices are sensitive right now with current warm temperatures and a lack of overnight freezing. Minimize time spent on slopes with large cornices looming overhead. They can break unexpectedly and act as very large triggers.

    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.

    Above-freezing temperatures could increase the likelihood of triggering a persistent slab avalanche. Surface slabs could step down to deeper, weaker layers, resulting in a larger avalanche than expected.

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