A police Marine Unit boat was sent out to rescue him and towed the boat into the harbor safely, the officer said. No one was hurt.
On the Southwest Side near Midway Airport, Chicago Fire Department authorities reported several wires down and some small fires from lightning strikes, but nothing major.
Area damage from the storm included the roof being blown off a retirement home in Aurora, displacing about 48 residents.
Wind apparently tore off the rubber membrane roof at the Constitution House, 401 N. Constitution on Aurora's west side, said city spokesman Dan Ferrelli.
No injuries were reported and the Red Cross was assisting in relocating the residents, he said.
Lightning struck the roof of a home in the 500 block of Hartford on the southwest side of Aurora, causing a small fire but no injuries. There also were numerous calls of wires down and tree damage, Ferrelli said.
The weather also temporarily halted Metra service on all Union Pacific-operated lines, which includes the UP North, the UP Northwest and the UP West, said Metra spokeswoman Meg Reile.
Reile said UP’s operating policy calls to stop trains when high winds are expected to exceed 50 m.p.h.
"High winds and trains can create blow overs, so it's a safety precaution," Reile said.
As the worst of the fast-moving storm started to move out over Lake Michigan, it left in its wake reports of winds as high as 80 m.p.h. and rains that delivered 1.65 inches of rain within 30 minutes in Yorkville. Midway reported 1.43 inches of rain in 30 minutes.
