The National Weather Service in Chicago issued a Lakeshore Flood Warning on Monday, because remnants of Hurricane Sandy are expected to move across the eastern Great Lakes by Wednesday.

Gusts of wind could reach 50-60 miles per hour and waves could rise 15 to 20 feet on the Cook County shoreline.

And while the Chicago area will not be experiencing a hurricane, the National Weather Service is advising residents to stay away from Lake Michigan during that time and not operate any watercraft.

Meantime, the Red Cross of Greater Chicago has deployed nine volunteers to the east coast, in case there is a need to open shelters.

Gentry Lassiter, Red Cross volunteer spokesperson, said the volunteers will help people prepare for the storm by teaching them what they need to do in case of an emergency. That includes stocking up on a three-day water supply for each person, keeping alert and listening to various communications, and keeping a supply of non-perishable foods and a first aid kit.

ComEd is also deploying 240 ComEd and contractor crews.

Spokesperson John Schoen said those crews will participate in any restoration efforts with their sister utilities. Half of the crews will go to Baltimore and half will go to Philadelphia.

Schoen said that it’s common for ComEd to deploy its units to areas that can potentially experience a disaster after a large storm.
