• Uncertainty is due to how the snowpack will react to the forecast weather.
• Forecast precipitation (either snow or rain) amounts are uncertain.

It's expected that natural avalanches will occur on Sunday as snow piles up, then turns to rain in the afternoon.

There have been no recent reports of avalanches.

Incoming snow and rain falls on 60 cm of snow from earlier in the week, which overlies a melt-freeze crust from the beginning of the year.

The mid and lower snowpack has two crusts that are between 50 and 150 cm deep. These crusts are not currently a concern.

The snowpack is generally well settled and dense.
