* from Friday evening through Sunday evening

* Rainfall totals of 1 to 3 inches over the past 24 hours has set
  the stage for a significant flooding event this weekend. A slow
  moving potent storm system will interact with a very moist
  airmass to produce heavy rainfall over the weekend. Forecast
  rainfall totals of 2 to 5 inches are likely with higher amounts
  possible across southeastern Missouri and southern Illinois.

* Heavy rainfall will result in flooding of low lying or poor
  drainage areas...and ultimately dangerous flash flooding on
  smaller creeks and streams. Significant rises on larger
  streams and rivers will also be possible.


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.
