Reply to "Comments on'Flash Flood Veri?cation: Pondering Precipitation Proxies'".

SCHUMACHER, RUSS S.; HERMAN, GREGORY R.

We applaud Gourley and Vergara for their thorough investigation of the relationship between precipitation and flash flood reports, as well as their inclusion of information from advanced hydrologic model output. We conducted some additional analysis to identify the reasons for the substantial differences between their findings and ours. The primary reason for the differences was found to be temporal sampling. The high temporal resolution of the MRMS dataset, as well as their use of "rolling" accumulation periods, explains most of the discrepancies. For guidance related to real-time warning decisions for flash flooding, Gourley and Vergara's analyses provide an important new guide and we recommend the use of their results for this purpose. For other applications, including model post processing and for precipitation datasets with lower temporal resolution, our results will continue to prove useful.
