Lake IL-Cook-
321 AM CST Wed Feb 26 2020

...LAKESHORE FLOOD WARNING REMAINS IN EFFECT UNTIL 3 PM CST THIS
AFTERNOON...

* LAKE SHORE FLOODING...North wind gusts of 40 mph and waves of 8
  to 12 feet will produce lakeshore flooding on the Illinois shore
  of Lake Michigan. Winds are expected to turn northwest this
  afternoon.

* TIMING...Through Wednesday afternoon.

* IMPACTS...The winds and large battering waves combined with
  record high lake levels will exacerbate already significant
  beach and shoreline erosion sustained in the past several
  months. Vulnerable structures along the shore may be heavily
  damaged. The water will likely threaten some roads and low-
  lying parks along the lake, as well. Large waves may sweep
  onlookers into the lake.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Lakeshore 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...and take
appropriate action to protect life and property.
