Rip Current Sensor GRAND HAVEN, MICH. (AP) (wgvu) - Researchers say they hope technology
used to predict dangerous weather conditions will help them warn
Lake Michigan swimmers about dangerous rip currents.
An Acoustic Doppler Profiler was recently installed near the
south pier at Grand Haven State Park. The device uses sonar to
measure the strength of currents along the beach and pier.
Grand Haven is the first location where the Doppler device is
being used to measure the strength of currents along Great Lakes
beaches.
Rip currents draw water near beaches away from the shore and
into deeper areas of the lake. They're blamed for the weekend
drownings of four swimmers, and the disappearances of three others,
in New York and Long Island.
