Avalanche Summary
No new avalanches were reported on Monday at the time of publishing.
There are several reports of small dry loose avalanches across the region on Sunday.
Snowpack Summary
20 to 30 cm of recent storm snow sits on surface hoar which has been seen on all aspects and elevations. A thick rain crust now buried 30 to 40 cm deep seems well-bonded at lower elevations, but may need more time to bond in the alpine.
Crusts and facets in the mid and lower snowpack can still be found in isolated pockets.
