A band of strong "derecho" storms swept across the Midwest on Monday evening, killing at least three people including a teenager who was swept away in a Cedar Rapids, Iowa, storm drain.

Logan Blake, 17, disappeared in the drain at an elementary school around 7:20 p.m. Monday, said city public safety communications coordinator Greg Buelow. He did not explain how the teenager ended up in the drain. The boy's body was found around 4 p.m. Tuesday more than a mile away in Cedar Lake.

David Bliss, 17, tried to save Blake but was also dragged into the drain and swept into Cedar Lake, Buelow said. The boy walked to a hospital and was treated for non-life-threatening injuries, Buelow said.

Buelow said the storm drain feeds into an underground concrete pipe about 4 1/2 feet wide at the school's culvert entrance. It is 10 feet in diameter where it empties into Cedar Lake.

Police said a man in northern Indiana was killed when a tree fell onto a trailer home and another died when strong winds caused a building to collapse in eastern Iowa. The raging storms left hundreds of thousands of people without power across Michigan, Indiana and Wisconsin.

Derecho windstorms occur once every year or two across the central and northeastern U.S. in a band from Texas to New England. They pack hazardous winds of at least 75 mph or more and maintain their intensity for hours as they sweep across vast distances.

In some cases a derecho will spawn tornados and accompany storms that produce hail the size of golf balls.
