...Significant rain this week will bring a threat of flooding...

Much of the southern half of Missouri and southwest Illinois is
expected to see periods of heavy rainfall early this week. This
additional rainfall coupled with the rain that has fallen since
Friday night will lead to a potential for flooding.

The heaviest rainfall totals will likely be found south of a line
from Columbia, Missouri to Pittsfield, Illinois, and north of a
line from Fredericktown, Missouri to Salem, Illinois. These areas
will likely see between 2 and 3 inches of rainfall between now
and Wednesday. There is the potential flooding of area streams and
rivers with this amount of rainfall. In particular, people along
the Illinois, Kaskaskia, and Cuivre Rivers could see minor
flooding from this rainfall. Significant rises may be possible
along the Meramec, Big, Bourbeuse, Maries, and the Moreau Rivers.

Locally heavy rainfall can be expected Monday night and Tuesday.
This could lead to localized flooding of roadways and poor
drainage areas.

People in central and east central Missouri and southwestern
Illinois should stay abreast of the latest forecasts and be
prepared for flooding throughout the week. Remember when driving,
do not attempt to cross a flooded roadway. The water depth is
often unknown, and the roadway may be washed out. Play it safe.
Turn around, don`t drown.
