An intense snow squall crossed Star Valley Monday afternoon. White out conditions accompanied the snow squall resulting in several accidents along Hiway 89 from Alpine to Thayne. A multiple vehicle accident occurred over the Snake River bridge in Alpine blocking traffic for over an hour.
Here are a couple videos from the Web Cams located north of the Snake River Bridge. The visibilities dropped to near zero very quickly with the squall.
