Primary Problem: Wet Snow
Bottom Line: Warm temperatures, wind-loading, and the possibility of rain and snow later in the week will drive avalanche problems. Wet snow avalanches will be the primary concern on most slopes. Get on to the snow early in the day when surface-level crusts are supportable and get off when the crust breaks down and more than the upper few inches of snow become slushy and wet. Relatively small wind-slab avalanches are possible on upper-elevation slopes that remain shady and cool. If the upper snowpack is dry, dig down and back off steep objectives if you find instability in your tests, observe shooting cracks or indications of fresh wind-loading. Reevaluate conditions when a mix of rain and snow moves into the area on Thursday and Friday.

The Last Word

We began our daily forecasts on December 7. 130 daily forecasts and 464 reported avalanches later, we wrapped up our daily forecasting season on April 14th. While avalanches remain a concern until the snow is in the rivers, read our SEASON SUMMARY to look back at the heart of the 2023-24 avalanche year.
