33-foot waves on Lake Michigan

Severe weather bearing down on the Eastern Seaboard could lead to waves as high as 33 feet on parts of Lake Michigan and dangerous conditions on other Great Lakes.  The National Weather Service has issued Great Lakes gale and storm warnings in effect through Wednesday. It says waves on Lake Michigan could be 10 to 18 feet by Monday afternoon, then build to 20 to 33 feet on Tuesday before subsiding. Waves on parts of Lake Superior and Lake Huron could top 20 feet.  Dangerous conditions are expected along piers and breakwalls in areas including southwestern Michigan. Snow linked to the storm could fall in parts of Michigan.  Hurricane Sandy strengthened early Monday, putting it on a collision course with two other weather systems that would create a superstorm.   (AP)
