Jasper.
Spring is coming, but with minimal effect thus far, as much of the snowpack remains cold and dry.A weak surface crust may be present on solar aspects at TL and below.
Weather Forecast
Clear and cold overnight Saturday, low of -15°C. Sunday, expecting clouds with sunny periods, forecasted high between -4°C and -8°C, with a notable temperature inversion expected. Light, westerly ridge winds. Mountain weather forecast available at Avalanche Canada.
Snowpack Summary
While much of the upper snowpack remains dry and faceted, dramatic seasonal temperature swings have begun a diurnal melt-freeze cycle to surface snow, especially steep southern aspects, BTL; but possible on all solar aspects and elevations. The mid pack remains strong enough to support a rider, but may be weak underfoot.
Timing, track, or intensity of incoming weather system is uncertain on Monday
Problems
Loose Dry
Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
