We have received quite a bit of new snow up high in the last several days. Temperatures have been good but we are seeing a fair amount of wind transport that often leads to slab instability.

Recent field work before this storm cycle showed sensative weak layers that were being easily triggered in places.

This new snow may have triggered some natural avalanche activity already. But in places that have not seen activity there is a possibility the mousetrap has been set.

With not much new snow in the forecast and temperatures holding or falling after today danger should remain moderate and is not predicted to rise greatly.

We are seeing continued wind transport that needs to be taken into account and could create very sensative weak layers in places.

It is still early season and we do not have a tremendous amount of snow yet so if avalanches were to occur we do not expect them to be of a size that would affect the urban areas of the city.

Danger is Moderate in the Urban Avalanche Zones. This is partially due to the lack of a human trigger for the avalanche. Remember in the backcountry danger levels may be more Considerable as you add the trigger (YOU).

Tip:

Please remember this is an avalanche forecast for the urban areas in the city of Juneau Only.

If you are a backcountry traveler please make sure you have the education and the tools to make good decisions and travel safely.

Remember, No Partner, No Tranceiver, No Probe, No Shovel, No Training??? NO TRAVELING IN AVALANCHE TERRAIN!
