Rare Weather Phenomenon Cuts Destructive Path Across Iowa

A major storm left a large swath across Iowa without power Monday. National Weather Service meteorlogist Jeff Zogg, says it was a phenomenon known as a derecho .

This storm got going before the noon hour and made its way across the state.

Winds were reported as high as 100 miles-an-hour and they knocked down trees, blew over vehicles, and left thousands without power. He says derecho doesn’t happen that often — but they leave an impression.

At one point more than 250-thousand people were without power across the state. The Iowa D-O-T warned that many roads, highways and interstates are impassable.
