ross campbell,
The avalanche hazard will be elevated today with no overnight freeze, warm temperatures, and rain!
Bears are waking up too, and have been observed at lower elevations.
Summary
Weather Forecast
Conditions will be warm, wet, and probably windy today as a warm front pushes past Rogers Pass on a NE trajectory. Freezing levels are forecast to reach 3000m today, winds will moderate from the SW gusting strong, and we could see up to 5mm of rain at lower elevations. Temperatures will decrease to 2000m overnight, and stay there for a few days.
Snowpack Summary
The snowpack has undergone numerous melt-freeze cycles resulting in several crusts in the upper snowpack on all but high (>2400m) N aspects, where one can still find loose, dry snow. Check out this link for more info on spring conditions. Expect the forecasted rain and warm temperatures to continue to destabilize the snowpack.
Avalanche Summary
Natural avalanche activity will increase today with rising temperatures, no overnight refreeze, and rain penetrating the snowpack. Cornices and Glide avalanches have been a common occurrence recently; however, we'll likely see some loose wet avalanches at lower elevations in steep unsupported terrain features.
Confidence
Problems
Loose Wet
Loose wet avalanches are possible today in steep unsupported terrain features. Glides and Cornices are also sporadically failing. It is best practice to avoid these features as much as possible with the current conditions.
- Avoid terrain traps, such as gullies, where the consequences of a small avalanche could be serious.
- Avoid slopes with glide cracks.
Aspects: All aspects.
Elevations: All elevations.
