Weather Forecast

Cooler temperatures are forecast through the weekend, with freezing levels remaining at valley bottom and alpine lows down to -20.  Little in the way of precipitation is forecast until the middle of next week.  Winds are expected to be light to moderate from the SW, swinging briefly N Friday morning.

Snowpack Summary

An early season shallow snowpack has accumulated over the course of several brief but intense storms. Wind speeds of over 100km/h had been observed prior to and at the onset of the most recent snowfall, as a result snowpack distribution is highly variable.

Avalanche Summary

Several size 1-1.5 slab avalanches have been observed in the past 48hrs from wind loaded alpine start zones near ridge top.

Confidence
