Tetons

Overnight temperatures were the warmest of the year, with only a few mountain and summit locations dropping to just below the freezing point. As temperatures quickly rise today at the mid and high elevations, the snowpack will weaken providing for the possibility of wet slides as well as the increased chance for human triggered slab avalanches to three foot depths in very steep terrain near cliff and rocky areas. Avalanches at low elevations are not expected today in the shallow to non-existent snowpack. Recent slab avalanches have occurred on Cody Bowl and an open slope near Wolf Peak. Note: The last forecast for the season will be issued tomorrow morning. Snowpack summaries and avalanche event data and mapping will continue to be updated periodically. Weather stations will continue to operate and attributes such as snowfall amounts, temperatures, and wind information can be monitored through the weather and snow link on our website. Thank you for your support this season.

Sunday morning looks to be dry followed by a chance of rain and mountain snow showers during the afternoon and evening. Isolated thunderstorms are also possible. Following overnight lows in the upper twenties, temperatures are to rise into the upper forties and winds are expected to have averages of less than ten miles per hour. The general avalanche hazard is expected to be MODERATE in steep wind loaded avalanche terrain where recent snow storms have deposited snow upon the older snowpack. Generally this hazard exists above 9000 feet although it does reach into lower elevations in the Southwest Trails area and isolated areas of the Tetons. As temperatures quickly rise Sunday morning, the snow surface will weaken providing for the possibility of wet slides as well as the increased chance for human triggered slab avalanches to three foot depths in very steep terrain near cliff and rocky areas.
