BOISE--A violent wind storm moved through the Boisearea Friday. The storm producedat least one funnel cloud,uprooted trees, damaged homes, and knocked out power in some communities.

Several eyewitnesses capturedthe funnel cloud on digital cameras and cell phone video as it moved through Boise around 3 p.m., when the National Weather Service issued a tornado warning for parts of Ada, Elmore and Boise counties. The warning expired about one hour later.
