The National Weather Service Forecasts-

TODAY...PERIODS OF LIGHT SNOW NEAR JUNEAU DIMINISHING IN THE MORNING. SNOW ACCUMULATION LESS THAN 1 INCH. OTHERWISE... DECREASING CLOUDS THROUGH THE DAY. BREEZY. HIGHS AROUND 27. NORTHEAST WIND INCREASING TO 15 TO 25 MPH IN THE AFTERNOON.

TONIGHT...MOSTLY CLEAR. BREEZY. LOWS 11 TO 21. EAST WIND 15 TO 25 MPH.

FRIDAY...PARTLY CLOUDY. HIGHS AROUND 29. SOUTHEAST WIND 10 TO 15 MPH.

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 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 danger should remain moderate and is not predicted to rise.

We are seeing continued wind transport that needs to be taken into account. This could create very sensative weak layers in places and even has the possibility to trigger natural avalanches.

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!
