The alpine rating is Storm Slabs and Wet Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeSpring conditions. Plan to travel when the snow surface is frozen and strong.
Summary
Weather Forecast
Mainly cloudy weather with a few convective showers are expected over the next few days. The daytime freezing level stays around 1200 m until Wednesday, when it begins to climb again. Winds rise to strong from the south for a time late Monday/early Tuesday.
Avalanche Summary
No recent avalanches have been reported. A couple of large wet slab avalanches were observed in the NW Inland area. Most operators have shut down for the season. Please continue to share your backcountry observations through the Mountain Information Network.
Snowpack Summary
Isolated storm slabs may be found in the alpine. At lower elevations, monitor the overnight freeze of the snow surface. If the snow surface does not freeze overnight or if the crust is only a few cm thick, the effect of daytime heating or rain will weaken the snowpack much more quickly than it would if there is a well frozen thick crust. Low elevation and thin snowpack areas are likely to be isothermal.
Problems
Storm Slabs
Isolated storm slabs may exist at high elevations.
Be cautious as you transition into wind affected terrain.>Choose well supported terrain without convexities.>
Aspects: All aspects.
Elevations: Alpine, Treeline.

Expected Size
Wet Slabs
Wet slabs are more likely at low elevations. Glide slabs are also possible, especially where the snowpack overlies a smooth ground surface.
Avoid slopes with glide cracks.>Watch for clues, like sluffing off of cliffs, that the snowpack is warming up. >
Aspects: All aspects.
