Lo esencial
It feels like spring in the valley bottoms but it is still winter up high and avalanche hazard still exists.

Treat cornices with extreme caution. They are growing with the new snow and winds and becoming fragile with the warming temperatures.

Expect loose wet avalanches to start running from steep slopes when temps warm up. Watch out for terrain traps where these small avalanches could have severe consequences.
Avalanche Summary
Wet avalanches have been observed in Waterton running up to 250m from steep aspects from the alpine on all aspects. Cornices have also be failing in the areas around Waterton running far.
Confidence
Due to the number and quality of field observations
Snowpack Summary
Warm temperatures and sunny skies will be triggering wet avalanches in the new snow at all elevations. The snowpack at higher elevation, including cornices, are still large and demand respect. Watch out for new windslabs.

Warm temperatures and no overnight freeze forecast for this weekend with daytime highs of 10C in the townsite. This will be accompanied with strong to extreme WSW winds and freezing levels to 2000m. More precipitation looks like its on its way Sunday night into early next week.
