Snow Characteristics Comments

Pick your poison today- deep, sticky glop or breakable crust. Wasn't expecting much but conditions were especially under-whelming. Have to wait for a lengthy melt-freeze cycle to settle the snow and allow for corn to redevelop.

Rapid Warming
Red Flags Comments
Signs of rapid warming were evident by 10:45 am even on north east facing shaded terrain. Had to abandon my intended route because of rapidly increasing instability. Rollerballs and treebombs were going off and loose wet triggered slides were happening by 11am. Temps peaked around noon to 1pm. With temps dropping throughout the afternoon I imagine loose wet activity decreased.

RAPIDLY warming temps this morning caused RAPIDLY  increasing instability. New snow from last weekends storm is now mostly damp except for MAYBE isolated shaded N facing pockets at upper elevations. Tomorrow's even warmer temps should affect all elevations and aspects.
