This document discusses using FFMP (Flash Flood Monitoring and Prediction) basins in AWIPS and Google Earth. It notes that while the FFMP program has worked well, the basins in AWIPS have some limitations like lacking topographical reference. The document suggests modifying the basins using county DEM data to better understand areas with rugged terrain, limited observations, and flood intensity issues. It provides examples of how modified basins could represent low water crossings, burn scars, high risk dams, and problem creeks/arroyos. The remainder demonstrates using ArcGIS to modify FFMP basins and export them to Google Earth to analyze past flood events.

1. Using FFMP Basins in AWIPS
and Google Earth

2. Aren’t FFMP basins already in AWIPS?
 FFMP program has worked well
• Program came out of
NWS Pittsburgh via Bob Davis
• Basins from NSSL via Ami Arthur
• Created basin centric thinking
 But there are some limitations
• No topo reference
• Fills in the whole basin

3. We do things different out West
 Rugged terrain
 Limited observation points
 Intensity more important than how much

4. What can you do with
modified basins
 Get to know your area better
 Low Water Crossings
 Burn Scars
 High Risk Dams
 Problem Creeks/Arroyos
