The spring and summer of 2007 brought an extended period of heavy rainfall to north Texas. Flash flooding resulted in over a dozen deaths and millions of dollars in property damage. Runoff from the heavy rains eventually led to significant mainstream river flooding. Tools such as real-time rainfall networks with high temporal resolution, traditional rainfall networks, flooded roadway sensor data, and radar rainfall estimates were used by National Weather Service forecasters. Data from several events in June 2007 will be used to illustrate the marriage of in situ and remote sensing data. This paper will discuss how the integration of these tools improved the warning process.
