Evaluation of precipitation in mountainous terrain has posed a vexing problem to many water-resources investigations due to the sparse and spotty network of reporting stations and gages. The creative application of convective cloud model precipitation model output can provide significant input in data sparse areas of mountainous terrain. Model application of the estimation of Probable Maximum Precipitation (PMP) for local storms related to summer thunderstorm activity can be used to assist in the calculation of Probable Maximum Flood (PMF) calculations. Model precipitation output can be used in the re-constitution of historical flash flooding events when integrated with radar observations and stream gage runoff data. Finally, convective cloud model precipitation output can be used operationally to provide quantitative convective precipitation forecasts (QCPF) as guidance in flash flood potential prediction.
