Avalanche Summary

2 avalanches up to size 2 have occurred in the Buller Creek area in the last 24 hours.

2 avalanches size 2 occurred on the south face of Mt. Nestor in the last 24 hours.

On Monday, there was a size 1 slab that was triggered by the forecasters in an open glade in the forest near the Dogleg area.

Travel in avalanche terrain requires cautious route-finding and conservative decision making.

Snowpack Summary

This last storm has deposited between 10-25cm snow (10cm to the North of the Spray and 25cm near the Dogleg area). Expect another 5-10cm by Tuesday morning. The milder temperatures along with strong winds have settled most of this snow into some sort of slab at all elevations. Recent strong/extreme winds in the Alpine have most likely left some widespread wind slabs, especially in lee features and cross loaded gullies. All of this is sitting on top of the Jan 30 interface (mostly a denser layer) and then below this is all facets. The forecasters do not trust the snowpack at the moment and are staying clear of avalanche terrain.

Weather Summary

Tuesday will be mostly cloudy with up to 7cm by morning. Temperatures in the alpine are expected to climb to -4c along with moderate West winds.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Wind slabs are most reactive during their formation.
  • Avoid steep terrain, including convex rolls, or areas with a thin, rocky, or variable snowpack.
  • Be careful as you transition into wind-affected terrain.
