JACKSON, Wyo. — With the arrival of new snow, avalanche danger has increased in the Tetons, according to a Friday, Feb. 14, forecast by the Bridger-Teton Avalanche Center (BTAC).
“Dangerous avalanche conditions have developed as new snow and wind will stress weak layers buried 2-3 feet deep above 7,500 feet,” BTAC wrote. “Large human-triggered avalanches will be most likely on north through east aspects where wind slabs can break on buried weak layers. Warming temperatures during the storm will create new snow instability at all elevations. Conservative terrain choices away from avalanche-prone terrain is advised, especially wind loaded slopes.”
BTAC rates the avalanche danger as “considerable” (level 3) above 7,500 feet and “moderate” above 6,000 feet. A Winter Storm Warning is in effect in Jackson Hole and Star Valley until 11 a.m. on Saturday, Feb. 15.
