Weather Forecast
We'll see little change in the weather pattern: valley cloud and cool temperatures down low but sunny and warm up high. SUNDAY: Cloudy with sunny breaks. Light to moderate south-west winds. Freezing level near 1500 m.MONDAY: Sunny with cloudy periods. Light southerly wind. Freezing level near 1500m with an above freezing layer at 3000 m. Alpine high temperatures near +3.TUESDAY: Sunny with increasing cloud in the afternoon. Light wind. Freezing level near 2000 m with a colder air layer in the valleys.
Avalanche Summary
Some small loose natural avalanches were reported on Wednesday in the south of the region with the start of the warming. Overall, we have very limited data. Please submit your observations to the Mountain Information Network (MIN).
Snowpack Summary
Daytime warming is melting upper snowpack layers, particularly on steep sunny slopes. Warming also has the potential to wake up more deeply buried weak layers which formed during November's rainfall. We have limited information about the nature of these buried crusts, but tests in the south of the region suggest they are bonding reasonably well there.Below treeline, the snowpack is shallow--look out for early season hazards like open creeks and tree stumps.
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.
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
