Some minor flooding along the Illinois/northwest Indiana Lake Michigan Shoreline today

Update 6AM CDT…

The Lakeshore Flood Advisory continues until early this Monday afternoon along the Illinois and Lake County, Indiana Lake Michigan shoreline. Strong northeast winds gusting over 30 miles per hour will continue to generate 7 to 10-foot waves on the already higher than normal lake, causing minor flooding on flood-prone areas along the Illinois and Lake County, Indiana shoreline. (green-shaded counties on the headlined map).  The pressure gradient will weaken with winds/waves slowly diminishing/subsiding later this afternoon into the overnight hours.

A Lakeshore Flood Advisory is in effect for later tonight until Monday afternoon along the Illinois and Lake County, Indiana Lake Michigan shoreline. With lake levels already some 3-feet above normal, strong east to northeast winds gusting over 30 miles per hour are expected to produce waves 7 to 10 feet, driving up lake levels and causing minor flooding along the Illinois and Lake County, Indiana Lake Michigan shoreline (green-shaded counties on highlighted map).

As a cold front moves south through northern Illinois and southern Lake Michigan this afternoon, winds are forecast to shift east-northeasterly. The pressure gradient will tighten, as cold high pressure presses in from the north behind the advancing frontal boundary, strengthening the easterly winds into gusts over  30 miles per hour and building waves with subsequent possible flooding in flood-prone areas later tonight into Monday.
