Avalanche Advisory
Advisory: Abajo Area Mountains Issued by Eric Trenbeath for Monday - November 23, 2015 - 6:44am
bottom line

Weak layers of faceted, sugary snow exist in the snowpack providing an unstable base for future snow to land on. These layers can remain for some time and are called persistent weak layers An isolated danger exists for triggering an avalanche on of these buried weak layers, primarily on mid to upper elevation slopes steeper than 35 degrees that face the north half of the compass. this danger will increase with the addition of more snow.
