Rain has ravaged the snowpack, especially on the east side of the park. Snow is completely melted in many areas. Hiking boots might be the best mode of travel while the snowpack rebuilds. Snow is forecast for tomorrow however this will only hide early-season hazards such as stumps and rocks. If you try and ski use caution.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
