8-14 day outlooks are for above normal temps and precip, temps should slowly come down to normal through the 2 week period
. Snow should accumulate in the higher elevations, the only problem will be is getting to it with marginal snow in the sno-parks. Rain amounts mid-week at the lower elevations could be significant
. Should be fairly windy also the next week. The conditions after next weekend should drastically improve for a more regular season, I hope.
Please be aware of high avalanche hazard with the long snow-less period and weak layers due to hoar frost formation. There is an increased probability of slab avalanches.
Grooming
As of now, still not enough snow for berm up or grooming. Grooming can
normally not start without at least a foot at the sno-parks, the berm up can start with less. I am hoping for enough to maybe get the berms up Tuesday night, we don't want to put them up and trap people up above them.
Chipping operations should be completed and the machinery gone from the Middle Fork by Tuesday night (I have been told, confirm before heading up), the lack of snow has enabled the operation to complete earlier than planned
.
I will update to the best of my abilities any new snow accumulations, with all my kids home for the weekend, my bandwidth is now severely limited...
