National Weather Service meteorologist John Taylor said the buoy is floating just south of the line separating Indiana from Michigan. It is the third such device providing real-time information on Lake Michigan.
"There is very little data over Lake Michigan," Taylor told The Times of Munster. "One was halfway between Milwaukee and Holland, Mich. There was another one north of there. There is a lot of real estate out there and we really don't have many reports. This just helps us understand things better."
Taylor said the information on waves and winds could help forecast rip currents.
The buoy is owned and operated by Illinois-Indiana Sea Grant and the Purdue University Department of Civil Engineering. Also using the buoy will be the National Oceanic and Atmospheric Administration's Great Lakes Environmental Research Laboratory in Ann Arbor, the Indiana Department of Natural Resources and researchers from Purdue.
