Red Flags
Red Flags: 
Heavy Snowfall
Avalanche Problem #1
Type: 
Wind Drifted Snow
Problem #1 Comments: 

Was noticing very shallow wind slabs in terrain above 10K this morning, 3-4" deep. They were quite sensitive, but not running really far and were very soft and shallow. Expect these will settle out fairly quickly, but there is tons more light density snow out there to form shallow slabs if the winds pick up again.

Avalanche Problem #2
Type: 
New Snow
Problem #2 Comments: 

Lots of shallow soft slabs in the afternoon during the high PI rates, both human triggered and natural. Mostly 4-6" deep. Very manageable in the right terrain. See photos below.

Would say in the morning we had a mostly moderate hazard, bumping up to considerable for a period during the high PI rates in the afternoon.

Today's Observed Danger Rating:

Moderate
