Weather Forecast

Stable weather for the next few days with progressively warmer temperatures over the next 48 hours especially east of the Divide.

Snowpack Summary

Hard slabs under ridge tops in isolated areas warrant careful consideration. As alpine temperatures increase over the next 48 hours, the possibility of triggering these may also increase.

Avalanche Summary

Human triggering of hard slabs up to 50 cm is a possibility.  Radiation on steep southerly aspects may result in loose snow avalanche that can be a factor in confined features such as waterfall ice routes.
