Avalanche Forecast
Regions: Little Yoho.
Expect poor isothermal conditions below tree line. Better overnight recovery is expected on Monday night.
Weather Forecast
On Monday, freezing levels should remain below surface, which will contribute to improving conditions and making triggering less likely. On Tuesday, a clearing pattern will provide opportunity for the sun to come out which will raise temperatures during the day and provide solar input to South and West aspects late in the day increasing the danger.
Snowpack Summary
Up to 20cm of moist snow sits over top of a crust that was formed last week. Many places below 2000m expect to find an isothermal snowpack.
Avalanche Summary
Today 3 size 2 avalanches were observed in the Vernillion Slide paths in Kootenay. The recent moist storm snow likely slid on a crust that was formed last week.
Confidence
Timing, track, or intensity of incoming weather system is uncertain on Wednesday
Avalanche Problems
Loose Wet
Below treeline expect near isothermal conditions with little freeze. At treeline and above, natural loose wet avalanches will occur if the sun comes out and the day heats up.
- Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Possible
Expected Size: 1 - 3
Wet Slabs
The highest likelihood for deep wet slabs is from daytime warming on solar aspects, or from periods of rain, especially from thin areas where slabs overly facets or depth hoar.
- Minimize exposure to sun exposed slopes when the solar radiation is strong.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Possible
Expected Size: 1 - 3
