Lake Michigan dual waterspouts put on a show

Two tornado-like water spouts formed on Lake Michigan Thursday, posing little danger but prompting questions from curious onlookers. The waterspouts, funnel clouds that often form on the Great Lakes in the fall when cold air blows over warmer lakewater, are usually much weaker than land tornadoes. 

Thursday's, which appeared off the western coast of Lake Michigan, north of Chicago, lasted about 15 minutes and caused no damage. "We did get a number of calls from people who wanted to know what was going on," said Kenosha, Wisc., Police Capt. Tom Hansche. Students in Kenosha Unified School District began emergency weather precautions but returned to class after about 20 minutes.
