Avalanche Advisory Archive 2016 – 2018

Date Issued:2017-02-01 07:06:10
Primary Trend:3
Primary Probability:3
Primary Likelihood:1
Primary Size:1
Primary Description:

We had significant winds last week from 20-70mph andd during both rain and snowfall event.
The lower mountain saw mostly rain and yet the upper mountain regions saw some new snow and significant windloading. Early in the storm there were multiple weak layers... Have those stabilized in the areas you choose to recreate?

At the end of the storm we picked up some cooler drier snow during considerable winds. This event also built windslabs. This newest slab is the most in question. It shoule be stronger now in most places.

Check the areas where you recreate... how many layers fromt he wind and last weeks events are you still seeing in your pits? Have those consolidated enough to now call them fully stable? or will they remain in question as additional load is placed.

Recognize that tonight into tomorrow we will see increased winds from a different direction. This will start the loading process all over again and danger will remain present although in different locations.

Secondary Trend:1
Secondary Probability:9
Secondary Likelihood:1
Secondary Size:2
Secondary Description:

The avalanche conditions are stable for the most part.

Glide avalanches always remain a concern if you have glide cracks in your region.

Best to always aviod slopes with glide cracks visible.


The National Weather Service- NEEDS TO PREDICT MORE SNOW>>> Ok... its a joke... work with me... COME BACK OLD MAN WINTER>>> WE MISS YOU>

Today- Clear early in the morning then becoming partly cloudy. highs around 32. Light winds.

Tonight- Mostly cloudy. Lows 16 to 22. Light winds. Northeast wind increasing to 10 to 20 mph near downtown juneau and douglas.

Thursday- Mostly cloudy in the morning then becoming sunny. Locally windy. Highs around 32. North wind 10 to 15 mph increasing to 15 to 25 mph in the afternoon. Near downtown juneau and douglas, northeast wind 20 to 30 mph, wind gusts to 60 mph possible in the afternoon.

We have not seen any real snow in the last few days after a week of rain and warm temps. The winds have been quite calm over the last few days as well. The little new snow we have has had several days to settle and bond. Temperatures cooled during the event and remain cool.

For the most part after the rains of last week the snowpack is stable in place. With no new snow in the forecast, and continued cold temps avalanche danger is LOW at this time. Natural Avalanches are not likely.

At the tail end of the rain we did pick up a little new snow during considerable winds. Recognize this windloaded areas with weak shallow slabs. Keep an eye out for these areas. Although stronger now their stability remains in question.
