bottom line

Even though the northern panhandle hasn't see snow in a couple days don't get tricked into thinking the snowpack is healed! The problem layers under the surface are alive and well... just waiting for the right trigger. Keep your guard up- Dangerous avalanche conditions still exist! Thank you everyone for the awesome observations recently! They've been really helpful!

There are a couple faceted layers  in the upper 1/3 of the snowpack that continue to be weak and show the likelihood to produce an avalanche. The rain and warm temperatures recently haven't affected these layers quite yet.

That November crust layer continues to hang out and show signs of weakness. There have been many avalanches in southern British Columbia stepping down to this layer. Be especially heads up if we get more rain in the next couple weeks. More rain = more weight = closer to the tipping point.

Disclaimer

Avalanche conditions change for better or worse continually. Backcountry travelers should be prepared to assess current conditions for themselves, plan their routes of travel accordingly, and never travel alone. Backcountry travelers can reduce their exposure to avalanche hazards by utilizing timbered trails and ridge routes and by avoiding open and exposed terrain with slope angles of 30 degrees or more. Backcountry travelers should carry the necessary avalanche rescue equipment such as a shovel, avalanche probe or probe ski poles, a rescue beacon and a well-equipped first aid kit.  For a recorded version of the Avalanche Advisory call (208)765-7323.
