Avalanche Summary

A late day road patrol had a few loose wet avalanches reported. All aspects and up to sz2. Yesterday afternoon saw a large avalanche in the second EEOR bowl. Sz 3, cornice triggered, ran on the deep persistent layer and wide propagation.

Snowpack Summary

Freezing levels were well above mountaintop today. The Burstall Pass weather station had +11 by 2pm. Moist snow on all aspects today. It's very much a spring snowpack up to about 2300m. Above that there are still layers, including the Feb persistent layer and the deep basal layers.

Weather Summary

Building cloud and increasingly gusty winds for tomorrow. Temperatures will still be above zero, but not by much. Overnight low of -5, high of +2. There may be a few flurries late in the day, but the bulk of the snow will be on Tuesday. It's a ways off, but we could get up to 15cm by Tuesday night.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • The more the snowpack warms-up and weakens, the more conservative you`ll want to be with your terrain selection.
  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
