Storm slabs could be about 1 foot deep by the end of the day Wednesday. You may be able to trigger avalanches big enough to injure or kill you near and above treeline. Expect drifts to form at upper elevations with gusty southwest wind Tuesday night. Below treeline, avalanches will be smaller. The likelihood that you'll be able to trigger these avalanches will be determined by the bond between new and old snow. Snow will fall on a variety of old snow surfaces, including moist snow and a recent crust buried around MLK weekend. Dig below the new snow to check for a possible poor bond.
Use small test slopes and quick snowpack tests to see if the snow slides easily on the old surface. Watch for fresh avalanches and cracks shooting through the snow. If you see these red flag warning signs, use caution on steep roll-overs and slopes steeper than 35 degrees. Avoid terrain traps where even a small avalanche could have serious consequences.
