Chicago Could See 23-foot Waves:
"Hurricane Sandy is so intense that it's expected to do a sort of victory tour of the United States after thrashing the Atlantic coast, and its ferocious winds are likely to push waves on the Great Lakes up to insane heights," reported the Atlantic Cities. The National Weather Service is warning Chicago and its suburbs of shoreline flooding from Lake Michigan as Hurricane Sandy could blow waves across the Great Lakes as high as 23 feet. The lake assault is expected to begin around 1 a.m. Tuesday morning and continue throughout the day.
