Seiche Warning on Southern Lake Michigan
a Lakeshore Flood Warning... also known as a seiche warning... which is in
effect until 9 PM CDT this evening.
A 2 foot drop in lake water near Chicago this afternoon indicates
that a seiche is in progress across Southern Lake Michigan. This
is a very dangerous situation for waders along the Chicago
Lakeshore. Water levels may fluctuate rapidly... taking
unsuspecting waders out to more open waters.
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. Evacuate docks...
piers... and breakwalls now.
