Very gusty conditions should be expected from this line of storms as well.

This fresh snow has added an avalanche danger to the area. As of 10 AM, an avalanche has already occurred north of Hailey between Trail Lane and Empty Saddle Road, according to the Blaine County Sheriff. The avalanche is estimated to be 10-15 feet deep, and is blocking the Big Wood River.

Officials are concerned about flooding, given the blockage of flow.

An Avalanche Warning remains in effect for this area, as avalanche danger remains high. Please be cautious traveling up in this area.

On top of snow and avalanche danger, blowing snow and strong winds are also a concern. Multiple roads are closed due to whiteout conditions, including State Highway 75 over Galena Summit, US-93/26/20 from Carey to Arco, and State Highway 46 from Gooding to the Camas county line.
