Beach Hazard Statement
Lake IL-Cook-Lake IN-
1105 AM CDT Thu Jun 21 2018


* LOCATION...Lake Michigan beaches in Illinois and Lake County


* FORECAST WAVE HEIGHTS...Building to 4 to 7 feet tonight.



Life threatening waves and currents are expected at the beaches.
People visiting the beaches should stay out of the water.

Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in
sandbars. Rip currents can sweep you into deeper water.

Structural currents form along piers where longshore currents and
wave action flow into the structure. Structural currents can
sweep you into deeper water along the pier structure.

Exposed beaches are more likely to experience the most
significant wave and current impacts. Impacts at beaches with
protective breakwalls or jetties will be subject to the
orientation of structures as well as wind and wave direction.

The National Weather Service in Chicago has issued a

* Flash Flood Watch for portions of north central Illinois and
northeast Illinois, including the following areas, in north
central Illinois, Boone, DeKalb, La Salle, Lee, Ogle, and
Winnebago. In northeast Illinois, Cook, DuPage, Grundy, Kane,
Kendall, Lake IL, McHenry, and Will.

* Through Friday mid morning

* Several rounds of heavy rain producing showers and thunderstorms
will move into the area both this morning into the mid
afternoon, then again overnight. These storms have the potential
to produce localized flash flooding as many locations across
these areas have received significant rainfall in the past week.
Rainfall amounts of 1 and a half inches up to 3 inches are
expected, with localized areas up to 4 inches.

* Area rivers and streams are running high, which will mean
rainfall will more quickly go into runoff. Urban and small
stream flooding is likely.


A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
