NOTE: Observations are currently very limited in this region.
Snowpack Summary
Forecast snow and southerly wind may form fresh storm slabs above 1000 m, rain below. Below the new snow is a thick crust at upper elevations and a rain soaked snowpack at lower elevations.
The snowpack is strong and well-bonded, but melting quickly at lower elevations.

- Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
- Use small, low consequence slopes to test the bond of the new snow.
