High
Avalanche Summary
No recent avalanches have been reported in the region.
Widespread natural avalanche activity is expected to begin on Wednesday as snow and wind develop sensitive storm slabs.
Snowpack Summary
New snow accumulates over a crust at lower elevations and wind-affected surfaces in the alpine and exposed treeline.
The mid and lower snowpack are generally well consolidated, and likely still moist from the recent rain. Conditions remain rugged at lower elevations, with a shallow snowpack.

- Storm slab size and sensitivity to triggering will likely increase through the day.
- Closely monitor how the new snow is bonding to the old surface.
Problems
Storm Slabs
Storm slabs will build over the day as new snow accumulates. Reactivity will increase as slabs become more cohesive. Deeper deposits are expected in north and east facing terrain around ridgelines.
