- Red Flags Comment
- <p>Lots of red flags out there today. Two inches of water weight and high winds should tip the scales in some locations with weak snow underneath. Natural class 2 avalanche on Superior along with other recent avalanches occuring. </p>
This is a good storm for up high but some low and mid elevation sites are getting a beating from the rain and warm temps. NRCS numbers for median SWE...

Snowpack
- Instability Comment
- <p>For tomorrow Persistant Slabs would be my number one concern. I would expect to be able to get propagation on ECT's still on N/NE aspects above 9500 in areas with a poor snowpack structure. </p> <p>Winds are currently cranking in the 30's on top of Baldy from the WNW. Lots of available snow for transport out there now. There is a possibility of wind slabs stepping down into weak layers out there in places. </p>
Since 1/6 Alta reported 2.03" of water with 14.5" of snow which gave us 14% density. Height of snow ranged from 70cm on south aspects at 8500 to 140cm on East aspects at 9600 where I traveled today.
