WorseningBottom Line
I toured in the Snowbowl backcountry today. Winds were moderate out of the northwest early in the morning but calmed after approximately 10 am. We found reactive storm slabs breaking in the top 4 to 6 inches (10-15 cm) of fresh snow on slopes steeper than 35 degrees. These would turn to sluff after a few feet of sliding. There has been 6 to 10 inches (15-25 cm) of fresh snow since Monday night (2/14).
