A premature and bonechilling shower for some morning joggers and bikers in the U.S. Midwest. Some unlucky residents of Chicago -- known as the "Windy City" -- got a dousing from the frigid waters of Lake Michigan on Friday morning. Strong winds caused 15 to 20 foot waves to slam over a retaining wall onto the city's famed Lake Shore Drive. Weather forecasters have issued severe wind and flood warnings for the region. No injuries were reported. Deborah Lutterbeck, Reuters.
