Red Flags
Red Flags: 
Wind Loading
Red Flags Comments: 
Winds were moving snow along the upper elevation ridgelines, but few wind slabs (see below).
Avalanche Problem #1
Type: 
Wind Slab
Problem #1 Comments: 

Despite wind and snow, was only finding shallow wind slabs right below cornices, and even these didn't want to crack out and move very much. That said, there was one observation of a shallow natural during a break in the weather in very exposed, steep terrain. In short, no doubt there are some wind slabs out there, but they were not as widespread as I expected. Tomorrows' hazard depends on what the winds do. If they stay strong, I would expect wind slabs to be a bit more connected and reactive tomorrow.

Avalanche Problem #2
Type: 
Persistent Slab
Problem #2 Comments: 

Two test pits in upper elevation northerly terrain indicated that the 0.6" of water added to the snowpack was not enough to reactivate our persistent weak layers. However, there is probably a slope out there that has been wind loaded enough to reactivate old weak layers.
