begin shortly. The heavy rain will fall across areas that have
already experienced extremely high rainfall totals of 4 to 8
inches over the last 24 hours or so.

Portions of southern Illinois in particular could see flash flooding
develop quickly once again. We are concerned about flash flooding
from Greenville to Perryville in southeast Missouri as well.

Carbondale, Marion, Jackson, Herrin, Perryville, West Frankfort,

dangers of flooding.

* Flood Warning for...
Perry County in south central Illinois...
Williamson County in southern Illinois...
Saline County in southern Illinois...
Jackson County in southern Illinois...
Franklin County in south central Illinois...
Hamilton County in south central Illinois...

* until 1130 PM CDT Saturday

* at 513 PM CDT, thunderstorms are forecast to move back across the
warned area through the evening. Even though several hours have
passed since the rains have ended, flooding in some areas remains
likely. New rainfall will only serve to redevelop flooding across
the region this evening as grounds are saturated and water levels
elevated.

If a Flash Flood Warning is issued for your area this evening,
move to higher ground and seek shelter immediately. Do not drive
across a water covered Road, period.

Precautionary/preparedness actions...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Stay away or be swept away. River banks and culverts can become
unstable and unsafe.

Flooding is occurring or is imminent. It is important to know where
you are relative to streams, rivers, or creeks which can become
killers in heavy rains. Campers and hikers should avoid streams or
creeks.

Please report flooding to your local law enforcement agency when you
can do so safely.

A Flood Warning means that flooding is imminent or occurring. All
interested parties should take necessary precautions immediately.

Flash Flood Watch
Issued: 4:40 PM CDT Apr. 29, 2017 – National Weather Service

... Flash Flood Watch remains in effect through late Sunday
night...

The Flash Flood Watch continues for

* portions of southern Illinois, southwest Indiana, western
Kentucky, and southeast Missouri, including the following
areas, in southern Illinois, Alexander, Edwards, Franklin,
Gallatin, Hamilton, Hardin, Jackson, Jefferson, Johnson,
Massac, Perry IL, Pope, Pulaski, Saline, Union, Wabash, Wayne
IL, white, and Williamson. In southwest Indiana, Gibson, Pike,
Posey, Spencer, Vanderburgh, and Warrick. In western Kentucky,
Ballard, Carlisle, Daviess, Fulton, Henderson, Hickman,
McCracken, and Union KY. In southeast Missouri, Bollinger,
Butler, Cape Girardeau, Carter, Mississippi, New Madrid, Perry
MO, Ripley, Scott, Stoddard, and Wayne MO.

* Through late Sunday night

* the Flash Flood Watch remains in effect for all of southeastern
Missouri, southern Illinois, southwestern Indiana, and a few
border counties of western Kentucky along the Ohio and
Mississippi rivers. Numerous thunderstorms with very heavy rain
are expected to spread eastward across mainly southeastern
Missouri and parts of southern Illinois this evening, and
develop there again overnight. This will only worsen an already
serious situation in this part of the region. Meanwhile, areas
further east may not see much precipitation tonight. However,
thunderstorms with very heavy rainfall are expected to expand
eastward into the rest of the region throughout the day Sunday.
Radar estimates of as much as eight inches of rain have already
fallen over parts of the watch area. An additional two to six
inches of rain is expected to occur before the storm system
exits the area Sunday night, with the heaviest rainfall expected
in the Missouri Ozark foothills. Locally higher amounts are
also possible where numerous thunderstorms move across the same
area.


* In addition to the possibility of flash flooding of some
roadways and streams, the heavy rainfall is expected to cause
further rises on many of the area rivers, particularly the
smaller rivers in southeast Missouri, such as the Saint Francis,
black, and current rivers. Given the widespread rainfall across
the region, other larger river systems, such as the Mississippi
and Ohio rivers will see rises in water levels occur in early
may. Due to the prolonged period of rain, some of the flash
flood warnings that are issued may be transitioned to overland
flood warnings.

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.
