The National Weather Service Forecasts-

Last night we received about 13mm of precipitation which added up to about 9cm of new snow at tram summit elevations. There could be several inches more at higher elevations.

Eaglecrest received about the same mid-mountain at the UAS Site.

Winds averaged over 20mph during the precipitation event from the South adding additional stress to the North facing slopes.

With less than .4\" of precipitation in the forecast for today avalanche danger is Moderate at this time.

There may be heightened avalanche conditions on specific terrain features. Be sure to evaluate snow and terrain carefully and identify those features of concern.

Natural avalanches are unlikely, yet human triggered avalanches remain possible in areas.

The snowpack is mostly stable. Be cautious of steep open faces with long runouts.... Be aware of possible windloading... Check to see how this new snow is bonding to the old snow surface in the areas YOU choose to ride...

Tip:

Special Thanks to SLF the Swiss Snow Institute...

They are town this week working on new urban avalanche mitigation studies...

We look forward to seeing what the world experts have to say about how to better our avalanche mitigation practices!

THANK YOU FOR YOUR HELP!
