Forecasting for dry and wet avalanches during mixed rain and snow storm events
Abstract
Professionals in coastal and some inland mountain ranges regularly face mixed rain-snow events. Professionals in inland ranges frequently deal with persistent slab avalanches failing on old faceted layers buried deep within the snowpack. What happens when you combine these snowpack and weather events? Widespread avalanching involving faceted layers during mixed rain-snow events is rarely observed and is not as well-understood. Last March, USFS Sawtooth Avalanche Center (SAC) staff observed this scenario.
