Stay alert to wind direction, as shifting easterly winds may form fresh wind slabs on new aspects.
Snow has been redistributed by strong south wind, and may continue to move as winds shift to the northeast. WInd slabs are likely found along ridges.
On Wednesday a natural wet loose cycle occurred on steep solar terrain as temperatures warmed and the strong sun came into play.
A few size 1 to 2 wind slab avalanches were observed around White Pass on Monday, along with significant wind transport. Small dry loose avalanches were also seen around Haines Pass.
Wind has redistributed 20 to 30 cm of recent snow, likely forming a mix of soft and hard wind slabs in open terrain while leaving some soft snow in sheltered areas.
A buried surface hoar or crust layer, 40 to 60 cm deep, is variable in distribution and has produced some test results but no recent avalanches. Similarly, a December crust with facets, 100 to 150 cm deep on all aspects up to 1750 m, has shown no recent activity or significant test results.
Snow depth ranges from 100 cm at highway elevations to over 300 cm in the alpine.
