Flash Flood Guidance Maps

 
Operational County-based FFG Graphics
(The images can be seen in more detail by clicking on the images or their labels.)  These products indicate the rainfall needed in the number of hours specified to begin flooding.  They are usually available daily by 19Z or within an hour after CRWFFGxxx products are sent out.  Blues and white on the color scale are relatively more serious and mean that it will take less rainfall to start flooding than the yellow and greens which indicate relatively drier conditions.
