Hurricane's effect on the Great Lakes

Mitch Smith, reporting for the Chicago Tribune:

Despite a four-state buffer between Chicago and the Atlantic Ocean, Sandy will affect weather patterns in Chicago. The National Weather Service issued a lakeshore flood warning for Lake Michigan that will be in effect from 1 a.m. Tuesday until 4 p.m. Wednesday. Waves fueled by Sandy’s winds could increase in size quickly by Monday night, National Weather Service meteorologist Richard Castro warned.

The Cook County coastline will likely see waves of 16 to 22 feet. A typical windy day in Chicago might bring waves of 4 to 6 feet, Castro said.
