8 am update: Be cautious of fresh pockets of wind slab in isolated terrain features at upper elevations.
Avalanche activity over the past week has been limited to small wet loose avalanches and cornice falls during periods of warm sunny weather.
A dusting of new snow is falling on moist or crusty snow layers, except shaded terrain above roughly 1400 m where the snow has remained dry over the past week. The middle of the snowpack is strong and contains numerous hard crusts. The lower snowpack is composed of weak basal facets. There hasn't been avalanche activity on it recently, but it will remain on our radar this spring as it may become active with abrupt changes to the snowpack, such as rapid loading (heavy snowfall or rain) or prolonged warming.
Cloudy, light flurries with 3 to 5 cm of snow, 30 km/h southwest wind, treeline temperatures drop to -8 °C with freezing level dropping to valley bottom.
