AVALANCHE DANGER MORNING AFTERNOON
Teton Area avalanche hazard rating for 04/19/2019
General Avalanche Advisory
Clear skies overnight and near freezing temperatures have frozen snow surfaces, and mostly stable conditions exist in the early morning hours. Mountain temperatures are starting out around 10 degrees warmer than yesterday morning, and the general avalanche hazard will quickly rise to Considerable above 7,500 feet as crusts break down and snow surfaces become saturated. As this happens, dangerous avalanche conditions will develop, and naturally releasing wet loose slides and large to very large wet slabs will become likely. Get a very early start, be prepared for the rapid development of wet slides, and get off of and out from under avalanche prone terrain before conditions become unstable. While the snowpack below 7,500 feet has undergone numerous melt freeze cycles, wet slides may still be possible where the snowpack remains. The final morning avalanche hazard bulletin of the season will be issued on Sunday, April 21st.

DESCRIPTION

Yesterday, abundant sunshine and warm temperatures resulted in significant avalanche activity as the April snowfall was substantially heated for the first time. Temperatures will be warmer today, and large to very large wet slab avalanches will quickly become likely at the mid and upper elevations. These slabs could be one to three feet deep and may be significantly deeper above 10,500 feet in the Central Tetons. Smaller wet loose slides will also become likely on very steep terrain features. These wet slides could travel long distances into low elevation terrain and may gouge down to the ground in areas where the snowpack is isothermal.
