JACKSON, Wyo. — The avalanche danger is expected to increase throughout the day in the Teton Range, from moderate at mid and upper elevations in the morning to considerable in the upper elevations later in the day, according to Bridger-Teton Avalanche Center (BTAC).
In the lower elevations, avalanches are unlikely and the avalanche danger will remain at low.
New snow amounts over the last 24 hours range from 6-10”. Snow densities are light, in the 6-8% range. With temperatures expected to warm, the new snow will be higher in density, heavier than the light snow below it. This creates an “upside down” snowpack, making avalanches more likely to trigger as the new snowfalls. Another 3-5 inches of snow is expected to fall today, with 8-10 expected in the next 24 hours.
“New snow and wind has formed slabs that will become increasingly sensitive to human triggers. With more snow expected along with increasing temperatures, expect slabs to become easily triggered in steep terrain,” said BTAC in this morning’s avalanche report.
The wind will also play a role in creating more dangerous conditions. Moderate south and southwest winds will help to build slabs up to 2 feet in depth in the upper elevations.
BTAC says natural avalanches will be less likely but it will be important to pay attention to changing conditions and assess the new snow for signs of instability.
“Be on the lookout for signs of recent loading and expect avalanche activity to be on the increase as the day progresses,” said BTAC.
Grand Targhee Resort will be closed to all uphill traffic until Thursday, April 14, as the resort performs end-of-season operations.
