* A cold front will drop southward into the area today. This front
  will become the focus for slow moving thunderstorms this afternoon
  and evening. Because of the slow motion and ample moisture in the
  atmosphere, storms may drop 2 to 4 inches of rain in a short
  period of time, resulting in flash flooding.

* Heavy rainfall in a short amount of time can result in rapid rises
  of water in streams, creeks, and urban areas.


A Flash Flood Watch means that conditions may develop that lead to
Flash Flooding. Flash Flooding is a very dangerous situation. You
should monitor later forecasts and be prepared to take action should
Flash Flood Warnings be issued.
