Loose snow avalanche
Loose snow avalanches (also called sluffs or point releases) vary in size, depending on how much snow is entrained and on the size of the terrain feature where they occur. Loose snow avalanches release immediately below their trigger point and are typically smaller and more predictable than slab avalanches.
Loose snow avalanche - Wikipedia
A loose snow avalanche is an avalanche formed in snow with little internal cohesion among individual snow crystals.
Avalanche types - SLF
Loose snow avalanches fan out from a point of triggering as they plummet downhill and sweep along more and more snow. This type of avalanche often occurs during or shortly after snowfall, or when significant warming occurs.
Loose Snow Avalanche - Avalanche Center Glossary
In warm conditions, or with rain, snow grains may have low cohesion due to an excess of water in the snow and wet loose snow avalanches (or sluffs) can occur. Metamorphism can also result in surface layers of snow faceting and loosing cohesion between the grains.
Types, Causes and Effects of Snow Avalanches
1. Loose Snow Avalanches. Frequent on steep slopes, these avalanches often follow fresh snowfall. The snow, lacking time to settle or loosened by sunlight, results in an unstable snowpack. These avalanches typically originate from a single point and gradually widen as they descend the slope. 2. Slab Avalanches
Recognize and distinguish types of avalanche| LAB SNOW - Ortovox Lab Snow
Loose snow avalanches, also known as point release avalanches, can be either dry or wet. They characteristically start from a single point and have a pear-shaped fall path. These avalanches are most often relatively small and hardly have the potential to bury someone.
7j - Avalanche Types - University of British Columbia
Loose-snow avalanches, also called sluffs, are made up of surface and/or near-surface snow that is not well-bonded. They begin at a single point, gathering more loosely-bonded snow crystals from the surface of the snowpack as they descend, gradually fanning out.
Anticipate Conditions - Sierra Avalanche Center
Loose Snow avalanches are the release of weak snow at the surface. They start at a trigger point and entrain more snow as they move downhill, forming a fan-shaped avalanche. Slab avalanches are the release of a cohesive layer of snow, or slab, with a weak layer below it.
Avalanche Problem Defintions - Sierra Avalanche Center
Dry loose avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs. Dry loose avalanches can trigger slab avalanches that break into deeper snow layers.
Loose Snow Avalanches · Safeback | Avalanche Survival Gear
A loose snow avalanche is an avalanche that releases from a single point and spreads downwards in a cone shape. The snow which first started moving at the top of the slope gradually picks up more and more snow on its way down, and the avalanche spreads out and becomes gradually bigger.
