Regions
Northwest Inland.
Sunshine and rising temperatures will elevate the avalanche danger throughout the week. Be aware of changing conditions throughout the day and avoid overhead hazards. This is our final daily forecast for the season which will expire on April 25th.
Confidence
Low - Due to the number of field observations
Weather Forecast
TUESDAY: Mix of sun and cloud. Light to moderate west wind. Alpine temperature +1. Freezing level 1500 m. WEDNESDAY: Sunny. Light northwest wind. Alpine temperature +6. Freezing level rapidly rising to 3000 m. THURSDAY: Sunny. Light southwest wind. Alpine temperature +10. Freezing level 2800 m.
Avalanche Summary
Avalanche reports have been limited due to very few information sources this time of year. If you have been out, please post your observations on the Mountain Information Network (MIN).
Snowpack Summary
Cornices are large and when they fail there is the potential to trigger large avalanches on deeply buried weak layers. Around 40 cm down (up to 100 cm in deeper snowpack areas) there is a weak layer of surface hoar on shaded aspects at high elevations and hard crusts on sun-exposed slopes and below treeline.Sugary facets exist near the base of the snowpack in shallow, rocky snowpack areas.
Problems
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.
Cornices
Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
