CHICAGO (CBS) — A high wind advisory that had been in place for parts of the Chicago area for much of the day has been cancelled, but a lakeshore flood warning remains in effect until early Wednesday, due to the effects of Hurricane Sandy.

The lake shore flood warning remains in effect along Lake Michigan until 4 a.m. on Wednesday. Originally, that warning had been scheduled to last until 4 p.m. Wednesday.

Huge waves, some as high as 22 feet, will develop through the day and tonight. The waves will create erosion that could lead to flooding along Lake Shore Drive and parts of Northwest Indiana.

Damage from wind was also a concern earlier in the day, with a high wind warning in effect for Cook County, and Lake and Porter counties in northwest Indiana. Those advisories were cancelled Tuesday afternoon, when winds began dying down a bit.

The chaos on Lake Michigan has been created by high winds, with gusts up to 55 miles per hour, created by the western edge of Hurricane Sandy, which pummeled the East Coast on Monday and Tuesday.

The winds are pushing Lake Michigan waters from north to south, creating the huge swells along the Chicago and Northwest Indiana shores.

A flood Warning means that flooding is occurring or imminent along the lake. Residents on or near the shore in the warned area should be alert for rising water.
