Regions
Northwest Inland.
South winds have likely formed fresh slabs that rest on a widespread crust. The best riding and highest danger are expected to overlap on high elevation north facing features. Even a brief appearance of the sun may initiate loose wet activity too.

Weather Forecast
The weather models continue to have a tough time with the current pattern and the region has been receiving less precipitation than forecasted over the last few days. Unfortunately there is still quite a bit of uncertainty, so take the following precipitation and wind speed values with a grain of salt. SUNDAY NIGHT: Freezing level around 1000 m, strong southwest wind, trace of snow possible.MONDAY: Broken cloud cover, freezing level holding around 1300 m, moderate southwest wind, a trace of snow possible.TUESDAY: Broken cloud cover, freezing level holding around 1300 m, moderate west/southwest wind, trace of snow possible.WEDNESDAY: Broken cloud cover in the morning with potential for some clearing in the afternoon, freezing level holding around 1200 m, light southwest wind, trace of snow possible.
Avalanche Summary
No significant recent avalanche activity to report. If you're out we'd love it if you would submit what you're seeing to the Mountain Information Network.
Snowpack Summary
5 to 20 cm of storm snow now rests on a weak layer buried April 4th which consists of crust, surface hoar and facets. The crust is widespread and up to 4 cm thick. Spotty surface hoar and facets have been reported on top of the crust on high elevation north facing slopes. Light to moderate wind generally out of the south over the weekend may have formed shallow storm slabs that may remain sensitive to human triggering.North facing alpine terrain also has a layer of facets down 30 to 50 cm below the surface, but this layer has not been recently active and is likely trending towards dormancy.Below treeline the snowpack is isothermal throughout much of the forecast region.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Loose Wet
Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
