Avalanche Summary

Nothing was seen or reported today.

Snowpack Summary

Some new snow will help refresh the skiing. Solar aspects will have a melt freeze crust to mountain top and North aspects are well settled. There may be some fresh windslabs from the recent intense winds on Sunday, so caution when transitioning into wind affected terrain. Remember the bottom of the snowpack is weak, faceted and full of depth hoar, this will remain with us until it melts away.

Weather Summary

Tuesday will be a nice sunny day with cloudy periods. A reasonable overnight freeze of -4° with day time highs of 0° and light winds out of the SW.

Freezing levels to rise to 2600m

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
