Snowpack Summary
Above around 1800 m, 5 to 15 cm of recent snow overlies a melt-freeze crust on all aspects except for north, where the snow may overly weak faceted snow or surface hoar. The snow has been redistributed by strong southerly wind. Another 5 cm is expected to accumulate during Friday. Below 1800 m, the snowpack is wet. Snow is melting rapidly at lower elevations.
Problems
Wind Slabs
Strong southwest wind has blown recent snow into lee terrain features, forming wind slabs. Use added caution above the rain-snow line, where these deposits may be reactive to human traffic.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Expect conditions to change rapidly with elevation.Watch for quickly changing conditions during periods of heavy loading from new snow, wind, or rain.
