"The Sierra Avalanche Center, a nonprofit avalanche forecasting organization conducted in partnership with the U.S. Forest Service, issues a daily forecast with a five-point avalanche danger scale. The center monitors the conditions of the Sierra Nevada region of California to warn the public about the chances of upcoming avalanches."
"The center's forecast discussion said 'weak snow' layers that were one to two feet below the surface were 'the most problematic layers' in the area snowpack before Wednesday's storm hit the region."
