Decreasing Danger
Problem #1 Comments

Loose wet affecting all the leftover dry snow above the March 22 crust, most particularly yesterday's couple-few inches. All aspects at mid and upper elevations. Should potentially lock up with cold front but much depends on the weather for tonight and tomorrow.

Wet Snow
Problem #2 Comments

No wet slabs noted today; however did see pooling in upper 40cm at 3/22 crust and at a couple interfaces above. 3/22 event greatly strengthened our snowpack otherwise. Can not rule wet slabs out for thinner snowpack areas, repeaters; etc. Again, much depends on overnight weather. Refreeze may only be superficial in nature.


On southerly terrain, might expect better plumbing as evidenced by stream flows adjacent to SR 210 (LCC).
