Snow Characteristics Comments
The mid and low elevations have damp snow underneath the new snow and at upper elevations mostly cold dry snow. Was surprised to find a rain crust below the new snow, nothing reactive while digging around, but might be something to keep an eye on?
Red Flags
Red Flags Comments
No red flags observed, but there has been lots of wind the last few days, but things seem to have settled out and are kind of glued in place. Some stubborn soft wind slabs that were very manageable today along the ridge lines.
Avalanche Problem #1
Loose Wet Snow
Increasing Danger
Problem #1 Comments
Would anticipate the new snow to get a little active once it sees direct sun for the first time and starts to develop into more of a slab.
Avalanche Problem #2
Increasing Danger
Problem #2 Comments
With warmer temperatures forecasted, the large cornices out there will become more tender and possibly breaking from the ridge lines.
This was the conditions yesterday at the trailhead, with rain, standing water and tough going just to get around. What a difference 12 hrs can make with colder temperatures and 8" of snow.
Nice and cool with some frosty trees up on the higher ridge lines and calm to light winds.
Mostly stable conditions today and riders were testing some steeper slopes.
About 8" new snow in the Double Hill area and it is sitting on a rain crust from the warm and rainy day on Friday. Will need to watch and see how this crust plays out with warmer temps and the new snow developing into more of a slab?
