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

The bi-state region is bracing for heavy rainfall early this
week, and this will bring with it a potential of 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 Vandalia, Illinois. These areas
will likely see between 2 and 3 inches of rainfall between now and
Wednesday. This amount of rainfall will likely bring the
potential of some local flooding of area streams. In particular,
people along the Illinois, Kaskaskia, and Cuivre Rivers could see
minor flooding from this rainfall. Significant rises can also be
expected along the Meramec, the Big, the Bourbeuse, the Maries,
and the Moreau rivers.

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

People in east central Missouri and southwestern Illinois need to
stay alert to the latest conditions over the next several days
and realize the high flooding potential that will persist
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
