If you live in Chicago, today is probably a bad day to go sailing. For the second straight day, Lake Michigan is being bombarded by winds gusting at up to 60mph, which are conjuring up waves up to 25 feet high. Wipeout conditions and some low-level flooding are expected along the lakefront, and the National Weather Service estimates the waves will sink to mere 15- to 20-foot levels by afternoon. The storm ripped more than a dozen boats from their moorings overnight and dashed them against a sea wall, the Chicago Sun-Times reports. (More Chicago stories.)
