Snow, wind, and warming are on the menu this week. Expect slabs to build and avalanche danger to rise.
Summary
Confidence
Fair - Forecast snowfall amounts are uncertain
Weather Forecast
Synopsis: The storm track looks like it will be aimed squarely at the Northwest for the next few days bringing a series of frontal systems. Expect 5-15 cm of snow on Tuesday, another 15-30 cm (or mm) Tuesday night through Wednesday, and it keeps coming down on Thursday. We should see a warming trend with freezing levels around 500-1000 m on Tuesday, and 1500-1700 m on Wednesday/Thursday. Winds should be consistently moderate or strong from the SW.
Avalanche Summary
A couple size natural size 2 wind slabs were reported from steep wind loaded terrain (northeast facing) on Sunday.
Snowpack Summary
Strong southerly winds are building wind slabs, generally depositing snow on N and NE aspects (other aspects may be getting cross-loaded or variable local wind effects too, so keep your eyes open). A surface hoar layer was reported to have been buried at the start of January in the northern part of the region. In the mid-pack, a crust weakness buried in mid-December seems to have fallen off most operators' radar for now. Near the base of the snowpack is a November crust-facet combination that could remain problematic, especially in shallower snowpack areas.
