The Illinois Environmental Protection Agency has issued an Air
Pollution Action Day for Sunday August 25th for the greater Chicago
Metropolitan Area through Sunday night.

A Chicago area Air Pollution Action Day is declared when weather
conditions are such that widespread ozone and or particulate levels
are expected to be at or above the Unhealthy for Sensitive Groups
category of the Air Quality Index for multiple days.

Active children and adults, especially people with pulmonary or
respiratory disease such as asthma, should limit prolonged outdoor
activity.

Area residents are urged to reduce pollution levels. Air quality
forecasts, current air quality, and tips on how you can reduce your
emissions can be found at www.airnow.gov.

Flooding of rivers, creeks, ditches, and poor drainage areas
possible across northeastern Illinois and northwestern Indiana later
this week. Significant river rises and renewed flooding possible
along the Iroquois, Kankakee, Des Plaines, Fox, and Illinois rivers.

Rainfall is expected to develop and move into the Midwest during the
day on Wednesday and continue through Thursday night. Widespread
rainfall of at least half an inch is likely, with localized totals
near 2 to 3 inches possible. Runoff from this rainfall will be
increased due to high soil moisture values across the region due to
recent wet weather. Significant rises are possible on area streams
and rivers, including the possibility of renewed flooding on the
Iroquois, Kankakee, Des Plaines, Fox, and Illinois rivers and their
tributaries. In addition to flooding of larger rivers, flooding of
fields, ditches, and poor drainage areas may also occur. Confidence
in the exact placement of rainfall and the exact rainfall totals
remains low at this time, which prevents more specific forecasts.

This outlook means that elevated water levels and potential impacts
are possible, but not yet certain. Persons with interests along area
rivers should closely monitor the latest forecasts including the
possibility of flood watches, warnings, and advisories.

This product may be updated tomorrow if the possibility of heavy
rainfall and flooding continues.

Flooding of rivers, creeks, ditches, and poor drainage areas
possible across portions of eastern Illinois and northwestern
Indiana later this week. Significant river rises and renewed
flooding possible along the Iroquois, Kankakee, Des Plaines, Fox,
and Illinois rivers.

Rainfall is expected to begin tonight and continue into Thursday and
Thursday night. Widespread rainfall totals of at least half an inch
are likely. Rainfall totals of 1 to locally over 2 inches are
possible east of I-55, and especially across northwest Indiana.

Runoff from this rainfall will be increased due to high soil
moisture values across the region due to recent wet weather.
Significant rises are possible on area streams and rivers, including
the possibility of renewed flooding on the Iroquois, Kankakee, Des
Plaines, Fox, and Illinois rivers and their tributaries. In addition
to flooding of larger rivers, some minor flooding of fields,
ditches, and poor drainage areas may also occur. Confidence in the
exact placement of rainfall and the exact rainfall totals remains
low at this time, which prevents more specific forecasts.

This outlook means that elevated water levels and potential impacts
are possible, but not yet certain. Persons with interests along area
rivers should closely monitor the latest forecasts including the
possibility of flood watches, warnings, and advisories.

rainfall and flooding continues.

Strong west to southwest winds gusting to 40 mph, dry vegetation,
and low relative humidity will result in a period of elevated
fire danger this afternoon. Any grass or brush fires that ignite
will likely become difficult to control. Exercise extreme caution
with any outdoor burning or open flames and with the disposal of
smoking materials.

Strong south winds are expected to gust to 40 mph at times this
afternoon. Winds of this magnitude in combination with very warm
and dry weather will create conditions favorable for the
uncontrolled spread of wildfires. Consider postponing any outdoor
burning today.

A fall storm system will move through the Great Lakes leading to
multiple rounds of soaking rain over the next few days. The first
round of soaking rain is expected tonight followed by the next
round Friday into Saturday. Repeated rounds of rain over the same
area with limited time for runoff and infiltration into the soil
may lead to localized flooding of low-lying and urban areas, as
well as streams and creeks. Rises in river levels may occur into
this weekend, as well.

Stay up to date on the forecast and heed any Watches, Advisories,
or Warnings issued for your area.
