* Slow moving thunderstorms capable of producing localized heavy
  rainfall are possible across the watch area today. Heavy rain in
  excess of two to three inches falling on already saturated
  soils could produce localized flash flooding.

* 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.
