Wet snow avalanches are possible today. GNFAC is warning us of possible increased avalanche danger due to the recent mild weather.
Wet avalanches were observed near Cooke City and near West Yellowstone by Hebgen and Quake Lake even on North facing slopes.
Because of the first major warm up of the season the snowpack is experiencing rapid change and dangerous avalanche conditions exit. For this reason the avalanche danger is rated CONSIDERABLE.
Wet snow avalanches are especially dangerous because they act like fast moving slugs of cement.
Here is link to the advisory.
