Osage MO...Pike MO...Ralls MO...Reynolds MO...Saint Charles
MO...Saint Francois MO...Saint Louis City MO...Saint Louis
MO...Sainte Genevieve MO...Warren MO and Washington MO.

* through late Sunday night

* Recent rainfall has set the stage for a significant flooding
event this weekend. A slow moving and potent storm system will
interact with a very moist airmass to produce heavy rainfall
over the weekend. Rainfall totals of 3 to 5 inches are likely
with locally higher amounts possible along the Interstate 44
corridor in Missouri and Interstate 55 corridor in Illinois.

* Heavy rainfall will result in flooding of low lying or poor
drainage areas...and ultimately dangerous flash flooding on
smaller creeks and streams. Moderate to major flooding is also
possible on larger streams and rivers.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch is advanced notice that conditions are
favorable that may lead to flash flooding. People in the Watch
area, especially in flood prone areas, should use this time to
make preparations just in case. Stay informed, and be ready for
quick action if flooding is observed or if a Flash Flood Warning
is issued.
