...More significant rainfall for the St. Louis region...

South central Missouri and Illinois are bracing for another round
of heavy rainfall developing late Tuesday night and continuing
into Thursday. This is coming on the heels of last weekend`s
historic rainfall event that dropped between 5 and 10 inches of
rainfall over the southern half of the St. Louis warning area,
triggering record flooding along the Meramec and Big Rivers.

With grounds still saturated from last weekend`s rainfall, runoff
from this week`s rain will develop quickly. Expect 2 to 3 inches
of rainfall south of a line from Hillsboro, Illinois to Troy,
Missouri, to Jefferson City, Missouri. This will likely trigger
additional flooding of small streams throughout the area and
prolong major flooding on the larger rivers.

People in this area 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 drown.
