...BEACH HAZARDS STATEMENT REMAINS IN EFFECT FROM 7 PM CDT THIS
EVENING THROUGH LATE FRIDAY NIGHT...

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

* HIGH WAVE ACTION AND DANGEROUS SWIMMING CONDITIONS EXPECTED.

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

* STRONG RIP CURRENTS AND STRUCTURAL CURRENTS EXPECTED.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH FRIDAY MORNING...

The Flash Flood Watch continues 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 morning

* Several rounds of heavy rain producing showers and some
thunderstorms will continue through tonight. These storms have
the potential to produce localized flash flooding as many
locations have received significant rainfall in the past week,
including additional rain this morning. 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.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.
